The U.S. government may finally mandate safer table saws

Amazed at the amount of people here who would clearly be against seatbelts if they were to be made a legal requirement today. So many people are certain it won't happen to them. Accidents happen, even to experts.

My dad had a table saw he'd been using for over a decade when he had an accident. Luckily they were able to stitch up the finger and he missed the bone, allowing the finger tip to regrow. But my family friend who's a professional carpenter isn't as lucky and is missing the tips of three fingers from a jointer.

These tools are dangerous and table saws cause upwards of 30k injures a year. Everyone's talking about how this will kill the industry. Are businesses not innovative around costs, new technology, and regulations? Seems like everything from cars to energy have all improved with regulatory pressure

And to all the people saying this will keep hobbyists away. Ever think of how many more people would be willing to buy a table saw if they knew they weren't going to cut their fingers off?

I think there are lots of people who would like to see this technology expanded. The issues going back more than a decade has been over the licensing of the patents. SawStop spent a lot of years aggressively suing over its IP and/or pushing for this legislation so that they could have regulatory capture. That's the problem, not the concept of safety. Maybe things have changed by now and we'll be able to see greater innovation in this space.

They offered to relinquish one important patent, but they have a huge portfolio of patents covering blade breaks specifically applied to table saws. If you go look at the actual testimony instead of a summarized article, SawStop's representative very explicitly will not even discuss relinquishment of their other patents including their patent on "using electrical signals to detect contact with arbor mounted saws" which does not expire until 2037.

A large part of the testimony was companies such as Grizzly complaining that SawStop is unwilling to engage with them in good faith on licensing their technology. Given SawStop's history, I'm unfortunately inclined to believe them.

And this right here is the key bit. SawStop was started by patent attorney Steve Gass. He has spent years claiming that other vendors won't talk to him while leaving out the actual terms of his licensing (which, by some rumors, was somwhere around "extortionate"). Bosch released a saw with similar tech in the US and then SawStop sued the product off of the market.

Every step of the way Glass has not acted in good faith and instead acted like a patent attorney. We have little reason to believe that he has all of a sudden found goodwill toward man in his heart when there's a dollar somewhere he could instead put into his wallet.

He also has a PhD in physics and was the person who designed and engineered the product: https://www.machinepix.com/p/machinepix-weekly-30-dr-steve-g...

Gass: I was out in my shop one day, and I looked over at my table saw, and the idea kind of came to me. I wondered if one could stop the blade fast enough if you ran your hand into it to prevent serious injury.

I started puttering around on how to stop things quickly. The simplest would have been a solenoid, but that would have been too slow and weak. I had come from RC airplanes—so I used the nose landing gear torsion spring from an RC airplane for an early experiment, that spring provided the force and I held it back with a fuse wire, a maybe 10 thou diameter fuse wire. I set up some capacitors to discharge through the wire and melt it in a few milliseconds, and I was able to generate maybe 20 lbs of force against a blade.

So this isn't one of those cases of a patent attorney taking over an existing invention/company.

Gass: Now that SawStop is established, any royalties Grizzly might pay would be less than what SawStop could earn by selling the same number of saws itself, and therefore, as I have explained, a license at the present time is far more challenging because of the risk it creates to SawStop’s business. This, of course, changes should the CPSC implement a requirement for table saws to include active injury mitigation systems. Should that happen, we have said we would offer non-discriminatory licenses to all manufacturers.

Insightful quote:

The fundamental question came down to economics. Almost a societal economic structure question. The CPSC says table saws result in about $4B in damage annually. The market for table saws is about $200-400M. This is a product that does almost 10x in damage as the market size. There's a disconnect—these costs are borne by individuals, the medical system, workers comp—and not paid by the power tools company. Because of that, there’s not that much incentive to improve the safety of these tools. Societally if there was an opportunity to spend $5 to save $10, we’d want to do that. But in this chain there's a break in people that can make those changes and people that are affected, so it’s not done.

This means seizing the ruling class gets to seize anyone's inventions. Nobody writing these rules intends that. But while we can forgive the first dozen attempts out of naivety and, later, stupidity, I'm not sure how we similarly excuse modern performances.

Patent expiration into the public domain is already “the ruling class seizing inventions” in the same sense (in the sense that it isn’t — in both cases, the goal is to make nobody profit from the patent any longer; not to transfer the profits to the government.)

Patents only exist as a concept, as a way to construct an equitable compensation for invention, to incentivize invention, that allows the market to determine what the total compensation over the legal lifetime of the patent should be, by licensing it or refusing to at given prices.

Insofar as an equitable compensation / patent “value” can be determined analytically on a one-off basis, you don’t need the patent system; the government can just buy out at that price, and the same goal will have been achieved.

Theoretically I agree completely. However in practice, analytically figuring out a dollar amount that isn't over or under paying seems nearly impossible. I fear that the gov would be buying out a lot of useless patents. That would also create an even bigger incentive to get BS patents through, because you don't even have to prove the value in the market, you just gotta convince a bureaucrat that it could be beneficial to humanity.

Why do you expect this? This doesn't happen with existing uses of eminent domain — lobbyist landholders aren't going around convincing the government to buy out useless land to their profit.

Eminent domain on real estate is only used as a last resort — it's invoked to buy out real estate where the government has some pre-existing plan that requires the use of the land; and there's no reasonable alternative to using that specific land; but the owner of the land doesn't want to sell it to them on the open market for a reasonable price (i.e. the price that they'd charge an arbitrary private buyer.)

I would assume eminent domain on patents would be the same: it would only be used if the government has a top-down plan that works out to require licensing a specific patent; with no reasonable alternative; but the patent owner is being obstructionist to licensing the patent for a reasonable price.

Exactly. Ideally we wouldn't have patents, but would have a "Star Trek" luxury space communism economy. Until then, if an invention proves to be highly beneficial to society after a few years, I would entirely support governments buying out patents early. In the end, information is a public good (non-rival, non-excludable), so let's start treating it that way.

That's clearly a false analysis - the size of a commodity market is determined as much by the equilibrium cost of making the goods as it is by the demand side. The cost of banning an inexpensive but essential part of your car would be far greater than the total number of dollars changing hands every year to purchase them.

It's not false, it's just ignoring the additional dimensions. In the same way that the societal cost of banning cars would be much higher than the value of the car (because cars enable commuting, leisure, cargo transport etc), the societal value of table saws in creating furniture, houses, whatever is much higher than the retail price of the table saw.

That’s a terrible analysis.

I assume the “cost” were injuries added up through remaining lifespan through lost work, etc.

But you can’t do a cost-benefit analysis without counting benefits.

So let’s add up all the benefits and value created by table saws.

True, it's not apples to apples to extrapolate downstream costs of accidents while not doing the same for the benefits. All manner of housing and construction would be much more expensive and slow without ubiquitous affordable on-site powered saws - not just reducing everyone's spending power, but also median quality of life with everyone's daily spaces severely limited by design/build potential.

Yes, there's an argument that society should be willing to pay up to the amount of the damage to prevent it. It's okay as far as it goes. However, that's equivalent to saying that if a safety improvement costs $1 to manufacture and saves $10 in damage, then the supplier should get the entire profit ($9). Although, he's just asking for $5. How generous!

This is a form of value-based pricing - figure out how much the customer values a thing and use that to persuade them to pay a higher price. Salespeople really like value-based pricing arguments.

Some safety measures are cheap, and suppliers can be bargained down. In the presence of robust competition, they could be bargained down to near the the cost of goods. But patents can result in a monopoly, along with monopoly pricing.

How much should you pay for tires? How about brakes? A vaccine?

In this case, I think he deserves to get rich from coming up with the idea, but there's still a lot of room for negotiation about how rich.

The Bosch design wasn't just similar, it was much better, by being non-destructive. Bosch instantly retracts the blade into the table using a $5 gas cartridge. Replace that cartridge and get back to work. By contrast, SawStop destroys a $100+ brake module PLUS your $$ saw blade every time it triggers (including false positives due to damp wood). To this day, I wish I could buy the Bosch design in the US.

Nitpick: It doesn't destroy your blade. You just have to get it resharpened and possibly get some new teeth brazed on.

Have you had a SawStop? It really doesn’t seem like it, because if you did you wouldn’t be so stuck on this line of argument.

Just getting saw blade out of the stop is a major effort with a vice and engineers hammer. The way it brakes is an extremely violent process.

It definitely warps the blades in weird ways, and fixing them to actually be true is unlikely to be economic.

Yes I have the industrial grade Sawstop. I ran a professional carpentry business for years using it as our main saw. I probably bought it around 2012 or 2013, I can't remember exactly.

I don't know what to tell you. I ran a professional shop, I'm not a hobbyist. I couldn't tell you how many feet of lumber I've shoved through my table saw. I've never personally had the Sawstop pop due to a safety issue, but every single time it happened in the shop I was able to remove the blade and get it serviced for around $30-40 depending on how many teeth were lost. Most of my saw blades are greater then $100 new so this cost is worth it.

In these cases no. It was stupidity of a different kind on my part, but never where I was in danger. For example I added a flexible ruler to one of my jigs without thinking about the fact that it was metal. The ruler (which I happened to be touching at the other end) touched the blade, so in essence the saw thought I was touching the blade.

Prior to owning the SawStop though I have had some close calls that would have been much less painful and dangerous had I been using a SawStop.

That goodwill is not warranted, nothing about Glass' or SawStop's behavior suggests that they're doing anything other than trying to force people to license their product by way of regulation. If they want to claim they are giving the license away, then do the whole patent portfolio (required for a functioning system), not just one of them.

They've already sued their competitors to keep similar products off of the market and there is zero reason for us, the regulators, or the competition to trust this organization.

It's certainly an interesting problem to examine... my understanding was always that patents were designed to foster innovation by giving an inventor a way to make money on their IP so long as they gave the idea to the world. Somewhere along the way that got weaponized. So is the solution that we need to reform patents, or do we need some other way to both allow innovators to make money but in a way that doesn't exploit other parties trying to expand the footprint of a good idea?

Likewise even assuming every injury were treatable, every person getting their thumb reattached or whatever because of a preventable injury means a doctor's time isn't available to treat other injuries that couldn't be prevented. uninsured individuals with these injuries also increase the cost of insurance (one of multiple reasons why our medical costs in the US are higher per capita). Nor is every injury treatable to that extent.

Bet setting that aside, if you really want the freedom to cut off your own fingers accidentally, I bet all the dangerous tablesaws that currently exist will become available at garage sales or whatever very cheaply, so the frugal consumer still wins.

Arguably gives a whole new meaning to five finger discount.

When public services are offered on balance, neither infringement can be considered in isolation. You have to compare the two infringements (in this case seatbelt regulation vs hospital responsibilities). Fighting each absolutely can often result in more total infringement!

I don’t think that’s why we mandated seatbelts. I don’t see any particular reason to believe either way, that seatbelts save money or cost it—if people die quickly they don’t cost the medical system much at all.

I think we mandated seatbelts because they prevent tragic deaths and cost almost nothing to manufacture. Sometimes we actually do impose on people’s liberty in the interest of preventing them from doing something stupid, and there’s no reason to pretend otherwise.

I mean, if we did look up the data and found that they actually do end up costing more, would you be in favor of banning seatbelts? I certainly wouldn’t!

I think it’s more about mandates from a government vs looking out for each other.

The original fear of mandating seatbelts was it becoming a slippery slope, and the government continuing to mandate other aspects of citizens lives.

A similar fear happened when drunk driving was outlawed, but obviously its implications in harming others was a good justification for it.

With seatbelts, it’s less harm on others if I don’t wear it, more so a strain on society as a whole (first responders, more serious medical attention)

In general though I agree that governments shouldn’t be mandating what individuals can do to themselves. The argument lies in how much those actions effect others in a tertiary sense (doing drugs only effects me, but if I go into a coma that’s a strain on society and a blurry line. If become violent because of those drugs, it’s more concrete)

Meanwhile alcohol is legal, and is involved in more murders and domestic violence than any other substance.

However, one key patent — the "840" patent — is not set to expire until 2033. To stave off potential competitors, it describes the AIM technology very broadly. In a surprise move at February's CPSC hearing, TTS Tooltechnic Systems North America CEO Matt Howard announced that the company would "dedicate the 840 patent to the public" if a new safety standard were adopted. Howard says that this would free up rivals to pursue their own safety devices or simply copy SawStop's. At the hearing, he challenged them "to get in the game."

Yes it can.

Sawstop, like a lot of other companies, abuse the patent process by filing multiple continuations with the exact same specification. They then let the patent office take its time granting some of them, and claim a 'patent term extension' due to the patent office delays.

So if they filed in 2001, but one of their patents wasn't granted for over 14 years due to the patent office taking 10 years in total to respond to the many arguments over patentability, it may expire in 2031. This seems absurd, but is totally legal. Being run by a patent attorney means they (a) are ninja level at drawing these arguments out and constantly filing appeals to continue examination after a denial by a patent examiner and (b) it doesn't cost them much to do so.

It's really not analogous to seatbelts.

It's really simple to use a table saw safely: don't ever get physically close enough (by far!) for the spinning blade to cut you, or stand where it can fling something at you.

Then even if there's no riving knife and blade guard it's not going to ruin your day.

This means that you'll sometimes need to build a small jig to push wood into the saw, but usually you can just use a long stick to push the wood into it.

Every single table saw accident video you'll see is people who've clearly become way too complacent with them, or are trying to save themselves a few minutes of setup time.

I disagree. If I'm going to be forced to collectively absorb risk, then I have a right to decide what risks people can take. The main issue is that it's not just the risk of death like you're suggesting, they usually just get severely injured and it's a drain on public health infrastructure, my insurance costs, and everyone else gets shafted when their serious injury gets moved to the front of the line. I've only been to the urgent care once, but a particularly bad car crash made us wait several hours. I've had appointments delayed because of risks other people take with their own life.

We're too closely connected in modern society to just let people exclusively decide what risks they want to take, because their risks are also our risks. I wish our collective wellbeing wasn't tied to the guy who wants to drive without a seatbelt, but that's the world right now.

Well written. I don't know why responsibility is so scary.

I've never used a table saw but I rock climb regularly which has plenty of risk. Are table saw accidents purely due to your own actions? Or is it like a motorbike where there are factors out of your control and someone could crash into you.

If losing your fingers on a table saw is 100% due to your own actions and there are no externalities, I would call that negligence not accident.

Sure! I'm withyou!

People who buy table saws with a failsafe mechanism should not be fined for not using the failsafe or disabling it.

...selling the table saw without that mechanism should be, however, banned - just like cars without seatbelts or airbags aren't legal to sell in New Hampshire (or any other US state).

I grew up as a proud resident of New Hampshire which has no such law on the books despite being one of the safest states to drive in the USA.

Last time I checked, you couldn't legally sell a car in New Hampshire which did not have seatbelts.

You're comparing apples to cardboard boxes here.

Motorcycles are legal so why shouldn’t driving alone without a seatbelt?

Irrelevant. The question you need to ask for a fair comparison is:

Motorcycles are legal so why shouldn’t SELLING A CAR without a seatbelt?

The answer is: because these are different vehicles with different use cases (and adoption levels) that require different kinds of licenses to operate and have different kind of negative externalities.

Same reason motorcycles aren't required to have airbags.

In the jargon of philosophy this a friction point between Deontology (rules-based ethics) and Consequentialism (outcome-based ethics).

Deontologically there is a strong case against seatbelt laws, but the consequentialist perspective is rather compelling.

I’m generally a deontologist but find myself supporting the seatbelt law. It’s just such a small price to pay when stacked up against the consequences. I guess that means I’m not really a deontologist.

A seatbelt is a small fraction of the total cost of a car. I wouldn't be surprised if a table saw with this feature is 10x the cost of one without it or more. It adds a ton of complexity to a fairly simple tool.

At scale the cost will come down. The actual tech is remarkably simple (which is a compliment to the design and engineering). The saw blade is wired up in such a way that it becomes a capactive touch sensor. When tripped a sacrifical brake is blasted into the blade that causes it stop and drop into the table.

It isn't going to cost 10x.

A table saw is a fixed position blade you feed wood into. A radial arm saw is a moving blade and the wood is stationary. Some of the cuts can involve pointing the blade directly at parts of your body, and then moving it without cutting yourself. A fixed blade is safer since you can try to avoid being in the blade area, but if the blade area is dynamic that becomes much more difficult.

A good video with examples (of pictures of recommended cuts, not injuries) is here: https://www.youtube.com/watch?app=desktop&v=Zeg8fHVrJBk

A good example is at 1:20 of the video.

I think bandsaws are much safer than table saws. The band saw naturally forces the work against the work surface instead of towards the user. You should give bandsaws another chance.

If I had a small hobbyist shop I think I would spend extra to get a big bandsaw and make do with a circular saw and a nice track. A circular saw and a router (for dados) can substitute for a table saw. You can't resaw without a bandsaw.

Mischaracterizing the issue, which is people handing over (or having taken from them) responsibility, to the state, for something they should be taking responsibility for.

No chance your father or your joiner friend hadn't seen those ads of the saws which automatically stop on contact. But they chose not to buy one, because they decided they didn't need one. They had that choice. Or if before those existed, to use a hand saw.

Regulation is nothing more than saying "we're superior to you in making choices for you, so we'll do so". And it's made not by efficient innovative geniuses, but by the same people who run the DMV. And it's not imposed on children by parents, it's on grown adults by other grown adults with no legal accountability. And it ossifies technology by locking in certain measures which will quickly drift out of date. And, as we've seen with the FDA and Opioids, it gives a get out of jail free card to wrongdoers who game the rules, because they can point to their compliance and say "so look, we followed the rules, we shouldn't be liable".

which is people handing over (or having taken from them) responsibility, to the state, for something they should be taking responsibility for.

It's just unbelievable people think regulation is in any way a good thing.

In general, there are many cases that most people cannot really take responsibility for. For example, if you hit a person with a car that can mean they’ll lose their income and need specialized care for decades. Such costs can run in the millions.

Now, you can argue people should take insurance against that risk. Problem is: some people won’t, and victims won’t be compensated,. If, then, you think the state should take on those costs, doesn’t the state have a say in what kinds of cars you can drive, for example that they have various safety features?

Also, this doesn’t only apply to cases where you injury others. If people get into an accident that leaves them with health costs they can’t afford to pay, we expect society to, at least partly pay up.

I think that argument applies here, too. Saw accidents can and do make lots of persons lose health and future income. In many cases, it’s the state that will have to pay up to cover that.

"These tools are dangerous and table saws cause upwards of 30k injures a year."

Right. I hate the damn things and they've always scared the shit out of me whenever I use them. I've not been seriously injured yet but I've come damn close.

Fortunately, I don't have one at present as someone stole my one during a factory move. I view this as good fortune for eventually I'll have to replace it and I'll do so with one with SawStop-like safety features.

I cannot understand what all the fuss and objections are about, yes SawStop-type saws are more expensive but their cost simply pales into insignificace the moment one's fingers go walkabout.

People are mad to say one can always use table saws safely. That may be the case for 99.99% of the time but it's the unexpected rare event that bites even the most seasoned professionals.

Table saws and their related brethren table routers are by design intrinsically unsafe, and this ought to be damn obvious to both Blind Freddy and the Village Idiot.

Frankly there's something perverse about those who consider table saws safe to use, alternatively they've misguided bravado and or they lack common sense.

Redesigning them to be intrinsically save just makes common sense, and in the long run will cost society much less (as amputations are enormously expensive per capita and it all adds up).

Edit: to those down-voters, I've a longtime friend who is one of the most meticulous and careful workers that I know (much more so than I am). Moreover, that planned thinking extends to the work he turns out, it's nothing but the finest quality.

He's been around power tools all his life and I first observed him using table saws and routers over 40 years ago. That said, about four years ago he was seriously injured when using a table router. Injuries to his hand were so severe that he has lost almost all of the dexterity in his hand, even now after many operations and ongoing professional physiotherapy, he has only regained partial use of his hand.

Perhaps the skeptics need to meet people like him and just see the negative impact such injuries have had on their lives.

It depends what the item is. Its intrinsic dangers and whether they're obvious or not to (a), the untrained and unskilled; (b), novices with little training and experience; (c), trained users but who are irregular uses and get out of practice; (d), trained users with regular/daily experience, (e), specialist users without experience or with little regular experience who take particular care in dangerous one-off situations; (f) specialist users who've regular/daily experience of dangerous situations; (g), any or all of the above under specialist/controlled conditions or in special environments and (h) any or of the above in emergency situations—who is selected and or authorized to take charge under under adverse/dangerous situations.

That list might seem like a lot of twaddle, but I'll illustrate with a few examples. Case (e) may involve an industrial chemist who is put in the unusual situation of having to deal with a dangerous, toxic and explosive chemical that's not normally found in common use—for example, pentaborane which comes to mind because it's a HN news item today. He knows what it is and its dangers but he hasn't dealt with it before so he goes to inordinate lengths to handle it safely. On the other hand, case (f) is a Similarly trained chemist with special training in the handling of pentaborane and he applies a regulated set of procedures to handle the substance.

Table saws are both intrinsically unsafe and have high impact when things go wrong which is borne out by statistics no matter the jurisdiction, country etc. Unfortunately, like motor bikes, they've been historically grandfathered into common use from an era when safety was hardly considered important.

Had motorbikes been suddenly invented today they wouldn't be allowed on public roadways. Same goes for table saws, they can be bought freely and anyone can use them without any training whatsoever. If invented today one would have to be trained and or licensed to use them.

We've seen how regulations change over time and how they are becoming tighter every day just about everywhere. When I was a kid, where I live anyone could buy fireworks including yours truly at the age of six. Now fireworks have been banned altogether here, not even adults such as I am who've (a) been trained in chemistry and (b) had military training and who was trained in handling things much more dangerous than fireworks for domestic consumption can do so either. I find this both irritating and irksome and an over intrusion of the nanny state into my affairs.

I'd suggest that those who voted down my original post also felt this way when they read my post, and I don't blame them one bit. The trouble is multifold, the State regulates, say fireworks after irresponsible use and after kids have become blinded. Regulations are introduced more from emotional reasons than based on actual harm to large numbers of people. The law now makes no exception for experience, nor does it allow exceptions for those with demonstrable experience (the only exception here is those with special training for public displays such as for new year's eve).

We've seen this progressive tightening of regulations in just about every country on the planet and in every field of endeavor—from drug regulations, to vehicle licenses, to firearm licenses and regulations, to restrictions on purchasing what the State perceives to be dangerous chemicals (when I was a kid local pharmacists sold thallium and strychnine for rat poison to anyone but they've long since been banned (I'd doubt if these highly toxic chemicals can still be purchased anywhere in the Western world).

The trouble is that laws and regulations are horribly uneven and often they extend into overregulation.

Now look at the facts: both thallium and strychnine were banned in many places decades ago because of a small number of accidental poisonings and an even much smaller number of deliberate ones. On the other hand, table saws—according to statistics—have maimed and ruined the lives of orders of magnitude more people than those poisons have ever done but it's only now that we are just trying to make them safer.

Unlike motor vehicles and forklifts, there's still no talk of training people before they can use table saws—nor is there any talk of requiring users to be licensed to use them.

When looked at objectively and in comparison with similar regulations elsewhere, this tightening of regulations in respect of table saws really isn't that unreasonable, and by other comparable standards it's long overdue.

I would recommend learning only one new tool at a time, rather than a suite of tools. It will be less onerous and scary learning the safety practices, and you will be far less likely to slip up. (Plus, it's more affordable to only buy a new tool as you need it.)

Also, some tools are a whole lot safer than others. Tools that carry a risk of flinging your project (such as table saws and lathes) are risky, but a lot of other tools (such as jig saws and tracks saws) are very unlikely to cause serious injury.

And, of course, you can do without power tools altogether. People have used hand tools exclusively for the vast majority of the history of woodworking, and many people today still primarily use hand tools because they are more precise, safer, and often easier to use (albeit slower).

I don't think seatbelts are an honest comparison, nor are you representing the arguments of others fairly here. Seatbelts are a strap you add to a chair. They don't significantly affect the function of a car, don't add much to the maintenance overhead or up-front cost, they are easily removable/replaceable, etc. This is a much more invasive legislation.

I actually love sawstops. In fact I don't use table saws that don't include that functionality. But I would never, ever push for this kind of legislation. I'm not sure if you (or anyone commenting here) have ever used one of these saws personally, but the added expense and ongoing operating cost is not negligible. It's about $150 to fix it every time it triggers. People love to say 'cheaper than a trip to the hospital!' and while that's true it's also pithy and hand-wavy given how often these things trigger.

There are a ton of edge cases that can make these trigger (including mysterious triggers that seemingly have no cause), and there are whole classes of people who don't make enough to deal with that regularly but still operate saws safely for entire careers. Those are the people that are upset, not hypothetical hobbyists, who are the most likely to be able to afford the extra cost and be able to always operate in pristine conditions.

Powertools in a site setting need to operate in all kinds of conditions, and for a jobsite saw the money spent installing sensors and gadgets to meet regulations would be better spent on literally anything else for such a tool. People working in those settings are just going to turn this feature off and will strictly be hurt by this. (There's no way they can force these features to be always-on as that would prevent tons of materials from ever being able to be run through a table saw again.) To make it literally illegal to produce the right tool for site workers is an overreach coming from out of touch people.

Woodworking is an interesting space where people generally accept the risks they take and in return are more or less trusted to make that assessment by regulatory bodies at least in the US. A better comparison than seatbelts would be the european regulations around dado blades, which as I understand are fairly unpopular. Sawstops are great for HN types. That doesn't mean it should be illegal to produce sensorless saws.

FWIW, I supervised in one of the safest industrial environments in the US, and also one with incredibly robust workman comp. The 18-25 year olds I supervised typically just found ever stupider ways to get themselves hurt or accumulate improper- or over-use injuries... Arguably we would just fire them before they got us in trouble, which we didn't, but neither do people in much riskier settings I've heard from ("get these stupid safety railings uninstalled once the inspector is gone, they just waste time and get in the way").

My suspicion is that the better analogy for these things is airbags rather than seatbelts. Because people don't use seatbelts (guards), install something expensive that can't be easily defeated, airbags (sawstops), which are touchy and known to brick the car (saw). Do sawstops, when not engaging, inhibit the function of the saw as badly as airbags inhibit visibility around A pillars?

SawStop saws work like any other table saw while you're cutting. The only difference is that you won't cut your finger off, though you are still vulnerable to kickback which is also dangerous. When I swap my regular 10" blade for an 8" dado stack I have to change the brake cartridge which only takes an additional minute. I don't change blades often so it's not a big deal. I've had my SawStop contractor saw for years and have never triggered the brake. On the other hand, blade guards, which are clear plastic things that go over the saw blade, do make using the saw more difficult imo. Lots of saws come with them now but basically no one, myself included, uses them as they obstruct what you're doing and are incompatible with certain types of cuts. I feel safe with a riving knife installed and using push blocks like the Grrr-ripper 3D to keep my hands far away from the blade at all times.

Opposition to a law mandating the use of certain safety equipment is not the same thing as opposition to the safety equipment.

Here in Seattle, there used to be a bicycle helmet law. Helmets reduce the severity of injury in a crash, less severe injuries are obviously better, forcing people to run less risk is therefore justifiable: it seemed to make sense, and it was a popular law.

And yet, it was repealed. Why? Disproportional enforcement, partially - tickets were inevitably handed out primarily to poorer and more marginalized people - but the law actually made things worse for everyone by reducing the total number of riders on the road. There is safety in numbers for bicyclists, who are less likely to be hit by motorists when they are a more common sight - but the health benefit expected from riding a bicycle at all, helmet or no, is actually greater than the health benefit expected by adding a helmet. It is therefore better, both collectively and individually, if we remove every possible barrier to bicycle riding, even though some people will choose not to ride as safely as we wish they might.

Unintended consequences are a real thing, so a person can quite reasonably believe that the SawStop is a great invention which everyone should use, and that a law mandating the use of SawStop would be a bad idea.

And then we run into forces bigger than us, and some people continue to defend their sovereignty. They want their freedom and they don't want to be told what to do.

I am a hobbyist carpenter and woodworker. My current project is probably the last one I will ever do without a table saw with these kinds of safety features. I have already changed over to using other tools like track saws and pull saws as much as I can for safety, but it is still hard to replace a well-calibrated table saw for certain tasks. My table saw is the only power tool I have that truly frightens me. Router tables and jointers can cause some nasty injuries as well, and I treat them with much respect, but total digit and limb loss is rarer with them.

The patent situation and much higher price are unfortunate, but it’s still a cost I am willing to bear. It’s cheap insurance compared to an ER visit and extended amounts of time spent feeling pain.

I am constantly amazed at the number of foreigners from first world countries who don't wear seatbelts or helmets the moment there is no Big Brother forcing them to.

If we're going to do a cost benefit analysis, we need to be pretty certain that the costs do in fact outweigh the benefits. We have hobbled Nuclear power over safety concerns and it's pretty clear we got that one completely wrong with huge negative consequences for society. This is obviously not on the same scale, but it's easy to get these things wrong and never revisit them. From the federal register notice on this, 70% of the supposed societal cost is pain and suffering, which frankly, individuals can decide on for themselves about the risks.

If you take out the pain and suffering values from these costs, you actually find that the cost benefit analysis doesn't pass at all, coming in at 0.5bn to 3.4bn in the red depending on the cost of the regulation on consumers, per the agency's own analysis.

If you got and read what people think about these regulations about people who use the tools, e.g. on /r/tools, they are unanimously opposed to them. Many people have complaints about the proposed products not working as advertised and generally wanting to bypass the system entirely: https://www.reddit.com/r/Tools/comments/19fmzko/are_you_in_f...

And that gets to the other part of this issue, if the regulation passes, what is the actual behavior change that will happen? Will people buy these saws and use them in the intended manner, or will they switch to alternatives that are just as dangerous, or will they simply turn off the safety features because the false positives are expensive ($100+ in direct costs without counting productivity losses). And note: all the SawStop products have off switches for the safety because they have false positives on wet wood and conductive materials like aluminum.

The headlines for these regulations are always great since nobody likes losing fingers, but there are always trade-offs, and it is extremely easy to make mistakes in these calculations and not foresee the actual knock on effects of them.

Particularly in this case where costs are largely internalized, rather than externalized.

Woodworker here. The equivalent SawStop to my basic table saw is 3X the price.

Your analogy wouldn’t make sense unless seatbelts tripled the price of cars.

SawStop has a huge patent portfolio and they’ve been cagey about actually letting other people use the full system. This is more of a regulatory capture play, not a safety play with consumers in mind.

floatrock

Key point here is the SawStop CEO is promising to open up the patent and make it available for anyone, so it's a bit more complicated than the typical regulatory-capture lawyer success story.

The 3-point seat belt is another time this happened and probably one of the few feel-good "this should be available to everyone" patent stories: Volvo designed it, decided the safety-for-humanity* benefits outweighed patent protections, and made the patent open for anyone. https://en.wikipedia.org/wiki/Nils_Bohlin (*: at least the segment of humanity that drives cars)

I'd be curious to hear the cynical take here. If I was to wargame it, I would guess something like: SawStop doesn't want to compete with Harbor Freight and cheap chinese tool manufacturers -- that's a race to the bottom, and power tools have turned into ecosystem lock-in plays which makes it difficult for a niche manufacturer to win in. So they'd rather compete on just the safety mechanism since they have a decade head start on it. They're too niche to succeed on SawStop(TM) workbenches, and they forsee bigger profits in a "[DeWalt|Milwaukee|EGo|...], Protected by SawStop(TM)" world.

The cynical take is more that it's crappy blade guards that nobody uses that really should be improved, and it's not necessary to mandate SawStop-style blade breaking technology.

I tend to agree with Jim Hamilton, Stumpy Nubs on youtube, who was quoted in this article: https://www.youtube.com/watch?v=nxKkuDduYLk

Bascially, mandating the more expensive blade brakes instead of standards around blade guards will eliminate cheap table saws from the market. And yes, this has happened before with radial arm saws - they are now basically non-existent in the US.

So it definitely benefits SawStop to give away this patent, as their saws will look a hell of a lot "cheaper" than competition.

SawStop often breaks the saw itself, not just the blade. There's alot of energy being put into the saw all at once, and I've seen examples where it fractured the mounts of the saw itself when it engaged.

I do it so seldom and am so careful not to put my fingers within 3 inches of the blade that this is a non-issue for me. This is another one of those "let's put 6 extra buttons that all need to be pressed to start the saw!" kinda situations that doesn't do anything to improve safety because the stop is the first thing you disconnect if it throws a false positive.

If we're concerned about job site injuries then let's address the real problem, which is that a lot of people using these things do so as fast as humanly possible with little regard for set up, site safety, or body positioning because the amount of money they will lose by doing that eats so much margin out of their piecework that it's not worth it. As usual we don't want to solve the hard problem of reducing throughput to improve safety, but we're perfectly happy to throw a part that is as expensive as the sawblade on the unit just to say we're doing something.

No, I mean they had table saw rigs that would bring the saw up/down into the floor with an actuator as a 'ring hazard', ie, your robot could be subject to sawing at any moment if they happened to be there.

The question is, how fast does it need to be? Likely not that fast really, certainly not microseconds, and an actuator could easily yank the saw down without damaging it if it detected you were about to lose a finger.

There's also no reason you couldn't use the same actuator to do fancy things, like vary cut depth on the fly, or precisely set the cut depth in the first place. Can't do any of that with a soft aluminum pad that gets yeeted into the sawblade when it detects a problem.

Basically, SawStop exists to sell saws. Those saws happen to be safer, but that's a marketing point, it's not what ultimately makes them money. Look at the incentives, you'll find the truth.

nemothekid

The question is, how fast does it need to be?

I don't know - the marketing material actually says 5 milliseconds. That's the crux of the problem and I don't believe you can actually move the saw fast enough to not cause serious damage to the human without damaging the saw. The problem, as I understand it, is stopping the saw. The saw actuator only makes sense if it moves fast enough and given the saw stop works on detection, I'm not convinced you have that much time.

I'm considering the physical reality here - if the saw must be yanked down quickly, how much force must be applied to the saw to move it, and then can that equal and opposite force be applied to stop it without damaging the saw?

Look at the incentives, you'll find the truth.

This is true of any safety device? The SawStop inventor created his company after trying to license it and eventually won in the marketplace after nearly 30 years. Surely his competitors would have released an actuator based solution if it is was possible rather than ceding marketshare of high end saws?

I think the other key variable is how fast is your finger being advanced towards the saw blade and how much total depth of contact are you willing to accept and claim a victory. In an aggressive ripping the material you're holding towards the blade that might be 10 mph (~15 feet per second), if you're willing to tolerate a 1/16" depth of injury, you have about a half a millisecond.

If the rate of advancement is much slower (like a normal pace of feeding the stock into the saw accident), you have several milliseconds before reaching a 1/16" depth of injury from first contact to last contact.

An entry-level Dado blade can run about $100. The $10-12 sawblades can't make finish cuts that are worth a damn, because they chew through the work and tear splinters out rather than making precise nips at the front and back of each grain of the wood. For a saw blade an entry level blade that doesn't do this to your work can run you more like $60.

I know this because I've had to buy a table saw blade to replace a $10-12 one on my wife's table saw that someone threw on there because they were doing framing work.

I have been associated with four hackerspaces that have SawStop's.

I have seen an average of about one false firing a month--generally moisture but sometimes a jig gets close enough to cause something. I have seen 4 "genuine" firings of which 2 would have been an extremely serious injury. This is over about 8 years--call it 10 years.

So, 4 spaces * 10 years * 12 months * $100 replacement = $48,000 paid in false firings vs 4 life changing injuries over 10 years. That's a pretty good tradeoff.

Professional settings should be way better than a bunch of rank amateurs. Yeah, we all know they aren't because everybody is being shoved to finish as quickly as possible, but proper procedures would minimize the false firings.

Part of the problem with false firing is that SawStop are the only people collecting any data and that's a very small number of incidents relative to the total number of incidents from all table saws. SawStop wants the data bad enough that if you get a "real" firing, SawStop will send you a new brake back when you send them the old one just so they can look at the data.

I have a beast of a radial arm saw, and I set it up to rip out of curiosity, and it would be insane to ever do it that way. It will cut your guts wide upon if you so much as slip.

I've seen all of the talking points, but a regulation probably is required simply to force liability.

The biggest "excuse" I have seen from the saw manufacturers is that if they put this kind of blade stop on their system that they are now liable for injuries that occur in spite of the blade stop or because of a non-firing blade stop. And that is probably true!

Even if this specific regulation doesn't pass, it's time that the saw manufacturers have to eat the liability from injuries from using these saws to incentivize making them safer.

As for cost, the blade stops are extremely low volume right now, I can easily see the price coming down if the volume is a couple of orders of magnitude larger.

I have a feeling these will be as ineffective. From SawStop FAQ:

"You can operate the saw in Bypass Mode which deactivates the safety system’s braking feature, allowing you to cut aluminum, very wet/green wood (see above) and other known conductive materials. If you are unsure whether the material you need to cut is conductive, you can make test cuts using Bypass Mode to determine if it will activate the safety system’s brake."

I have a feeling that you have never used a sawstop. You can not "turn on the bypass and never turn it off." As soon as you hit the stop paddle the bypass mode is disabled. You must reenable the bypass mode every time you want to pull the paddle. If someone is dead set on getting stuff done the bypass procedure gets old quickly.

Have you ever used a sawstop? How did you turn on bypass mode forever?

Table saws, in spite of being used far less than kitchen knives, account for far more digit amputations and more serious ones.

It is pretty uncommon and rather difficult to cause yourself a digit injury that cannot be recovered from with a kitchen knife. Bad technique is most likely to lop off the end of the fingertip which can fully regrow so long as the cut isn’t very deep.

Mandolines and meat slicers (guards are bypassed when cleaning which happens every 4hr, they also tend to be used by 16 year olds) are much much more dangerous but they tend to be dialed in quite shallowly which limits the damage.

Table saws are THE most dangerous thing for your fingers because of where people tend to put their hands when using the tool and how they can go right through your digits and how they’re dialled in to make thick cuts. The logic that well if we accept kitchen knives we shouldn’t have safety regulations on table saws doesn’t make sense because table saws are far more dangerous and unlike with kitchen knives it’s actually possible to enforce the default use of an effective safety mechanism which ensures a cut will usually be shallow enough to be recovered from. Of course some people will disable the brake excessively but the average person will likely keep it on most of the time.

You can argue we shouldn’t have this safety regulation because it will add costs to consumers, and point out that other safety approaches already exist, the safety paradox, but the comparison to kitchen knives doesn’t really make all that much sense. I’d argue adding saw brakes as a standard feature makes a ton of sense due to the high social cost of digit amputation and the inconvenient and frequently ignored use of other safety approaches.

More experienced customers are likely using the saw more often so I wouldn’t presume this only or primarily benefits the inexperienced.

First digit amputation (100% recoverable) I caused myself happened after spending most of my life using a knife because I just got complacent and was cooking when I knew I was extremely fatigued. Wood is also a natural product where natural variance can cause a table saw to operate in unexpected ways that catch people off guard.

My understanding is that the excess cost isn't so much the safety device itself but that cheap, flimsy table saws can't handle the extreme torque created by stopping the saw more-or-less instantly, so the device is limited to higher end equipment that's heavier and has better build quality.

If it costs 200$ to add the device and modify the saw to accept it and the original saw cost 300$ you've got a pretty massive increase.

I’m paying about $50 service fees for the two blades currently out for repair. The 10” replacements cost over $200, and the 8” dado would require buying a new stack… around $250. The same folks who sharpen and true my blades do the repairs. They’re local to me here in Maine.

Ruminating a bit:

Cheaper blades are replaced more often with use and can’t generally be sharpened; SawStop tech doesn’t change the lifetime of a blade unless an activation happens. So, if you’re already willing to run to the box store for another blade semi-regularly, whether one survives activation perhaps isn’t material?

On the other hand, somebody who doesn’t regularly use their saw is probably both more price conscious and less likely to need sharpening/replacement often. I assume they care most about whether an activation forces them to buy a new blade (and a $100 brake). I suspect those are the people who propagate “SawStop = trashed blade”. For them, it’s true.

I'm actually kind of surprised that any implementation destroyed the blade. Like I don't actually care that the blade is moving, I care where the blade is moving. It seems like a trigger to yank the blade under the table would be the easier and more obvious way to do it.

So we're somewhat lucky from an engineering standpoint. Because the blade is circular the only interval of time that really matters is from detection to first movement away. Because it triggers on touch the difference between getting sawed and not is millimeters. The time from first movement to full retraction only needs to be fast on human scale time in case the person's hand is still moving into the blade. Name brand SawStop is actually fairly slow on the retraction because it uses the blade's momentum to drive it and that's plenty of speed.

However, the blade-preserving system puts the explosive between the table and the pivot that's already there for retracting the blade. The full explosion force is there to force the blade down and it ends up being faster than the SawStop. Which while cool the SawStop was already fast enough so it's all the same.

So I don't know, I guess to me I'm surprised that the solution we jumped to first was a brake when the action of moving it out of the way takes far far less energy. It's only the energy to move the weight of the blade and bar down at the requisite speed, instead of needing to absorb the full energy of the spinning blade.

Do you mean in a system with both moving it away and a break?

The only time my fingers hit the blade of a table saw they were moving with a fair amount of momentum and hit first low on the blade - dropping the blade at the speed of gravity wouldn't have been enough.

I haven't seen an explosive system like you mention - is that what Bosch had for a bit? - so I don't know just how fast that is, though dropping a spinning-towards-you blade also seems to have some other potential risks of grabbing shit with it, too. If it's fast enough I wouldn't be concerned as much, but at relatively slow speed it seems maybe nasty.

It took the better part of a decade to get close to the light quality that incandescent bulbs produced, and we're still not really 1:1.

For alot of things, that's fine, but I distinctly remember having to bring clothing over to a window because the bulbs I had would not render the color of it accurately enough to put an outfit together. That's partly the clothing manufacturer's fault for using cheap dyes that are prone to metameric failure, but still, annoying.

I'm still in the process of purging the early gen LED bulbs that I have with nicer, high CRI, High Ra, variants, and getting dimmable bulbs in the places where it matters, because around me, the incandescent rollout was more of a rugpull when LED's first came out, and I snagged a couple bulk cases of cheap LED bulbs to use that were... not great.

I do keep a few decorative 'eddison' bulbs, aka squirrel cage bulbs, for reading use, as they are very warm, like 2300k, and the light they produce is very comfortable to be in at night. They use a ton of power, but, because they're not running their filaments as hard as they could, they tend to last forever. I've had one go out in ~10 years because I had removed it for cleaning and dropped it while it was hot (and also because it was hot), the envelope survived but upon being turned back on it ran for about a second before failure.

All of that to say, yes, there were downsides, mostly short/mid term downsides, some that persist to this day if you're not clever or don't know what to care about.

If you go listen to their CEO's testimony, he clearly states that the one single original patent behind the idea is now open but was expiring anyway. He brags about them spending a lot of money on R&D and needing to recoup that, reiterating that they have many other patents that aren't being opened that cover the exact implementation. He talked about them exploring those other methods, choosing not to patent them, and only patenting the best solution.

All his words. He's trying to explain that sure, the patent is open, but companies are still going to have to work harder than Sawstop because they have many more patents they refuse to open that cover the best and most logical implementation of this idea.

You're asking for a "cynical" take, but it's not really cynical! The CEO is trying to tell everyone, openly, and they're not listening. They are NOT altruistic, otherwise they would have opened the entire suite of patents. They are openly saying this singular patent is open, because it doesn't matter and that they will doggedly defend their other patents. Now, every other manufacturer will now need to navigate a minefield of patent litigation, and follow the path of subpar implementations that Sawstop ruled out during their R&D.

You need to improve upon it and have a new claim.

If I was to patent A and make it, and then patent B which improves upon A at some point in the future, when A's patent expires someone else can make A and if they show that they're making A and not B, there's nothing I can do about it.

The issue is that often B is better than A (why make a 223,898 light bulb when you can make a 425,761 light bulb?) so while you could make A, its not commercially viable to do so.

The thing is that I've got a research line looking at making improvements on B and patenting C later which is a further improvement on B. The investment of time, knowledge, and resources to be able to do refinements of A to make B, C, and later D - that's where it's hard to get into it.

Someone else could improve on A to make B' and if it was different than how I did B, they could patent that. Though in the real world, this often involves in hiring away people who are familiar with A and investing a lot of time / money into making a B' that might get interpreted by the courts as too similar to B.

Yeah, i looked at the proposal in more depth and it proposes 36 months from publication until the rule takes effect [1]. That does seem like a lot of time (the proposal itself notes that this is longer than usual).

I guess the benefit to SawStop is that they sell a better product, but turns out most people won't pay 2-3x the price for the added benefit. If they can make everyone implement the same feature, then they still probably won't compete on price, but the price difference will go down, and perhaps people will pay a low to medium premium for a slightly better safety mechanism.

As far as regulatory capture goes, it doesn't sound particularly nefarious. I do believe that the folks at SawStop genuinely believe this is necessary regulation.

How about SawStop open their patent up first? They've already sued to prevent other tool manufacturers from making their own solutions to the problem, because they want theirs to be licensed. So even though they claim they will open their patent once the feature is enforced, what have they done in good faith to make us believe they won't move the goalposts to opening it, once they have captured the market?

SawStop was never against licensing the technology, and from what I'm reading about FRAND, it doesn't force the patent holder to open their patents, only to negotiate in a good faith manner that does not discriminate between licensees, meaning they cannot license the tech to DeWalt for $10/saw and try to make Bosch or Ryobi pay $100 per saw. It doesn't say they are forced to give away their IP for free.

afaik the patent was basically expiring in the next couple years anyway, even the small ancillary ones. They've been making and selling SawStop saws for the last 20 years and already made their bag. So, since SawStop has the experience designing and building the systems they want to wring out some good will and see which Big Saw manufacturer wants to pay them to get ahead of their competition.

Compare the difference in effect between having a copyright on iOS and having a patent on "mobile device with a touchscreen display". In one case you can do a comparable amount of work to make a competitor, in the other competition is entirely prohibited.

The patent[0] is over 20 years old so it should have expired regardless - except it got 11 years of extensions. That's a bit of an odd situation because SawStop was selling "patent-pending" saws since the very early 2000's...I'm not sure the extension guidelines were intended to give companies 30 years of exclusivity and protection - it would make more sense in a situation where they couldn't start profiting on the patent until the patent was finally granted. There's a reason they're supposed to be 20 years from "date of file" instead of "date of approval". The current system could encourage companies to try to get their patent applications tied up in appeals for as many decades as possible.

Regardless, it would have made sense for them to agree to FRAND [1] licensing >5 years ago which might have accelerated standards adoption.

From https://toolguyd.com/sawstop-patent-promise/ :

I am a patent agent and I just took a look at the patent office history of the 9,724,840 patent. It is very interesting because it spent a long time (about 8 years) being appealed in the court system before it was allowed. While patents are provided with a 20 year life from their initial filing date (Mar 13, 2002 for this patent) there are laws that extend the life of the patent to compensate the inventor for delays that took place during prosecution. The patent office initially stated that the patent was entitled to 305 days of Patent Term Adjustment (PTA) and that is what is printed on the face of the patent. But the law also allows for adjustment due to delays in the courts, which the patent office didn’t initially include. So SawStop petitioned to have the delays due to the court appeal added and their petition was granted indicating that it was proper to add those court delays to the PTA. So the PTA was extended to 4044 days, meaning that this patent doesn’t expire until 4/8/2033!

The other interesting thing about this patent, is that its claims are very broad. Claim 1 basically covers ANY type of saw with a circular blade that stops within 10 ms of detecting contact with a human as long as the stop mechanism is “electronically triggerable.” It would be VERY difficult to work around this patent and meet the CPSC rules. So the fact that SawStop has promised to dedicate this to the public is at least somewhat meaningful.

BUT, SawStop has many other patents that it has not dedicated to the public. I have not analyzed their overall portfolio, but is is very likely that the other patents create an environment that still makes it difficult to design a saw in compliance with CPSC rules. So it is entirely possible that the dedication of the one broad patent was done to provide PR cover while still not creating a competitive market.

"curious to hear the cynical take here"

My first cynical reaction is to ask which politicians will benefit handsomely from stock trading with SawStop stock (assuming it's a publicly traded company) or through kickbacks of one kind or another.

I think SawStop table saws are terrific for woodworkers who work in their own shop. Less so for workers who have to bring their tools to the job site. Yes, I know that SawStop makes a portable table saw. When you're working at a job site, you have less control over the materials you're working with (as compared to the cabinet maker in his/her own shop). SawStop technology isn't compatible with all materials that need to be cut at a job site. A common example mentioned is treated lumber, but I don't recall ever having cut treated lumber on a table saw. When I need to cut treated lumber it's with a hand held circular saw. I'm a part-time handyman (some evenings and weekends).

You can turn the tech off to make it work as a regular table saw, but it does require pre-existing knowledge about what may false-trip the saw. Having a job site saw fail on site without cartridges and blades in supply, or a newbie on the saw could be pretty bad.

Not overly prohibitive with training though, and is something that everyone will face if this becomes mandated.

It's idiotic that health insurance companies aren't clamoring to buy out SawStops and hand-deliver them to everyone with a table saw, asking them to install them at no cost in exchange for an insurance discount.

It's idiotic that health insurance companies don't pay for gym memberships and reduce your premiums if you deliver them screenshots of your workouts and pictures of making healthy food at home.

That's what a sane insurance company that wants to increase profit margins would do. Get out there in the field and reduce the number of times they need to pay.

One thing I don't see mentioned with any of these discussions is that this massively increases the cost of using different kinds of blades on the saw. If you need to use a specialty blade that's a smaller diameter, it requires a matching special size safety cartridge. Dado stack? Another, even more expensive cartridge. I know most people typically have one blade on the saw and never change it or if they do, it's just another of the same size, but for those of us who do regularly swap out blades that aren't the standard 10" x 1/8", these types of regulations add both significant cost and time/frustration.

I'm all for safety and would love for there to be more options for this kind of tech from other saw makers, but I personally don't think regulation is necessarily the right way to do it. Just like there are legitimate cases for removing the blade guard, there are legitimate cases for running without this safety feature, especially one that would require several hundred dollars more investment even if the safety feature is disabled (On SawStop, you physically can't mount a dado stack unless you buy a special dado stack cartridge).

And if SawStop really wanted to improve safety for everyone... well I find it rather telling that they'll only open their patent if the regulation becomes law. Since they're effectively the only ones with the tech, with the regulation passed, buyers instantly have only one option for however long it takes for competitors to come to market with their own (which they'll be hesitant to do based only on a spoken promise by the patent holder). Instant pseudo-monopoly.

It takes 3 minutes to swap out the normal saw stop cartridge and put the one in for dado blades. Setting up the thickness and putting the dado stack on takes twice as long. If you are doing enough woodworking that you have a dado stack and specialty blades the saw stop cartridge is not that big of a deal.

That really is the crux here.

If the technology is allowed under free-use or a free limited license, that'll change things.

Right now, no one can put it on their saws without having to either risk the patent fight or pay whatever Sawstop wants, with the later probably being so high, there is a reason other brands don't have "Equipped with sawstop technology!" badged on them.

If I had 3 years to implement a safety feature based on a patent to meet new legal requirements I would be concerned about getting sued for edge cases the patent holder worked out.. Injurues are reduced but buyer beware may no longer apply to the remaining injuries especially if even other new implementations avoid edge case largely by accident, I.e. slightly different materials and other factors not considered when only one manufacturer was attempting the feature.

My cynical take is:

1. Many of SawStop’s patents either expired or about to expire.

2. Bosch already has a similar tech but was prohibited to sell their saws with it in the US. I think soon all the patents that were basis for this ruling going to expire.

3. SawStop already by acquired by TTS(same company that owns Festool). They may have plans to integrate it in their line up somehow and safety tech becomes less of a differentiator.

And my even more cynical take is that FTC only considered requiring safety tech after a nod from the industry leaders.

He is opposed to this but expects it to pass. His best argument is that it would effectively outlaw affordable low end "contractor" portable job-site style table saws. I have one of those, a cheap $150 Ryobi. It would be more like $450 with the SawStop feature and I would not have been able to afford it.

I'd be using a circular saw instead. Maybe that is a bit safer, and at least it's more affordable until they require the same tech in circular saws. But shouldn't I be the one to weigh the value of a risk to only myself against the value of my fingers?

"He is opposed to this but expects it to pass. His best argument is that it would effectively outlaw affordable low end "contractor" portable job-site style table saws"

"job site saws" account for 18% of the market, just to put this in perspective.

It is also totally wrong. The submitted comments to the CPSC suggest an increase of $50-100 per saw, even with an 8% royalty (which will no longer exist).

That is from PTI, who is the corporate lobbying organization of the tool saw manufacturers and plays games with the numbers.

In the discovery of the numerous lawsuits around design defects in table saws, it turns out most of the manufacturers had already done the R&D and come to a cost of about $40-50 per saw.

Everything else is profit.

We already have riving knives and you name it, and injury cost is still 4x the entire tablesaw market.

It's worse if you weight it by where injuries come from.

For every dollar in job site saws sold, you cause ~$20 in injuries.

The one dollar goes to profit, the $20 is paid by society, for the most part (since they are also statistically uninsured).

Let's make it not regulation - which seems to get people up in arms.

Here's a deal i'd be happy to make (as i'm sure would the CPSC) - nobody has to include any safety technology.

Instead manufacturers are 100% responsible for their weighted share of blade injury costs (whether the user is insured or not).

If the whole thing was profitable, this would not be a problem.

Suddenly you will discover their problem isn't that there is technology being mandated, but they don't want to pay the cost of what they cause.

(In other, like say cars, you will find the yearly profit well outweighs the yearly cost of injuries)

That $50 number seems incredibly optimistic. Just the rebuild cartridge is selling for $99 right now: https://www.sawstop.com/product/standard-brake-cartridge-tsb...

And the saw frame has to be much stronger to handle the force of stopping that blade. Throwing $50 of new parts on an existing frame just means you throw the whole saw away after it triggers.

Every time this triggers, you need a new cartridge and blade ($40+) and time to swap them in. If I was sure this was saving a finger (as the dramatic stories in the press state), then I wouldn't think twice. But it probably just wet wood or something else conductive causing a false trigger. Show me the false rate data please.

"That $50 number seems incredibly optimistic."

It's not.

"Just the rebuild cartridge is selling for $99 right now: https://www.sawstop.com/product/standard-brake-cartridge-tsb..."

The BOM on this cartridge is not $99 or even close :) Sawstop has said this themselves.

"And the saw frame has to be much stronger to handle the force of stopping that blade. Throwing $50 of new parts on an existing frame just means you throw the whole saw away after it triggers."

First, you are assuming sawstop mechanism. Most alternative mechanisms are closer to https://www.altendorfgroup.com/en-us/machines/altendorf-hand...

or

https://www.felder-group.com/en-us/pcs

or similar.

None of them required significant saw frame changes, and none of them require blade replacement. All have been tested repeatedly to respond and prevent injuries in the saem time (or even faster) than sawsotop.

The saw frames can already handle stopping the blade, even in job site saws (and definitely in any cast iron trunnion table saw). Please give any data that suggests it can't?

Again, i'm also telling you what the manufacturers said. Go read the discovery yourself, don't argue with me about what their own data said.

"But it probably just wet wood or something else conductive causing a false trigger."

This is wrong.

"Show me the false rate data please."

I cited it in another post, and honestly, i'm not going to spend my time trying to convince you your particular set of opinions is wrong. There are lots of people with lots of them

Why don't you do the opposite - this data is easy to find and there is a ton of it - discovery in table saw design defect lawsuits, tons of submissions and hearings in the CPSC, etc. Why don't you read a bunch of it, preferrably prior to forming and asserting strong opinions.

That's a good way to become better informed.

This thread already has plenty of misinfo in it (job site saws are a small fraction of the market, for example, despite people thinking it's the majority), it doesn't need more.

what the manufacturers said You expect me to believe that? Really now. And the BOM is not the only cost, but +$50 on the BOM is probably +$100 retail.

What will the manufactures try to extract is the better question? Answer: As much as they can.

The only other saw with similar technology (Bosch) to hit the US market cost 50% more than the similar SawStop product. They had to pull it due to patent issues (despite attempting a different approach), so we don't have good market data on how well it sold.

This just reeks of regulation forcing everything to be more expensive. I'd rather just see the patent go away and see what the market really does. I really can't image this technology being added to low end saws for less than $150 retail and then you have the per activation costs. It really kills the low end market, when a minimal saw is $500.

So, basically, your opinion is both more right and more valuable than the manufacturers own emails, R&D costs, BOM's, and retail costs produced in discovery.

Why? Because otherwise you might have to admit that you actually have zero data to back the opinion you offer in the last sentence.

As for Bosch, they have admitted they priced the Reaxx very high on purpose hoping to capture a premium user and avoid regulation. They knew they were going to get sued off the market. In fact, they were later granted patent rights for free and once that happened, suddenly, well, you know, we don't wanna. Because it was (as discovered later) literally intended to stave off regulation through game playing, not do something real. Of course, you would know this if you would bother to read any of the actual data i pointed you at

I'm remarkably aware of what happened here - i attended the CPSC hearings and also have read all the lawsuit data.

But please, continue to just not produce any real data to back up your view because then you might actually have to change it.

I'm not going to respond further unless we are going to have a real conversation here that doesn't consist of me producing data and facts and you just saying "yeah well i like my view better".

Product market fit is a real thing. I'm a typical low end table saw user. You can ignore me at your peril, but many people will have similar values.

I just finished a flooring project that made use of the table saw. My low end $350 saw was perfect for the rip cuts. There isn't another tool that would do it as well, but I might be tempted to try if a low end table saw starts at $500 (which is already way lower than the cheapest SawStop sold today). Do you have data on safety of alternate ways to solve a problem when the obvious solution has been priced out of reach?

As far as what manufacturers promise, I want to see the contract. We been promised "it will be so cheap you won't even notice" so many times that I just assume is marketing bluster from the get go. They will charge what the market will bear and they will exit if there isn't enough profit. Things they said in a committee room are meaningless. The only thing we know for sure is that what has worked so far is about to get banned.

Obviously I don't have time to do all the research you have done. I'm just a typical low end user who is looking at what it will cost me and what options are likely to disappear.

But what does this even mean? You don't injure yourself with existing saws if you follow safety protocols. Then people don't and get hurt, which is entirely from not following safety protocols.

The manufacturers can already be sued if they make a product which is dangerous even when used appropriately.

Suddenly you will discover their problem isn't that there is technology being mandated, but they don't want to pay the cost of what they cause.

Or each manufacturer will file a patent on their own minor variant of the technology such that no one else can make a replacement cartridge for their saws, then sell cartridges for $100+ while using a hair trigger that both reduces their liability and increases their cartridge sales from false positives.

Meanwhile cheap foreign manufacturers will do no such thing, provide cheaper saws and just have their asset-free US distributor file bankruptcy if anybody sues them. Which is probably better than making affordable saws unavailable, but "only US companies are prohibited from making affordable saws" seems like a dumb law.

Having safety protocols doesn't matter if it's something deployed in situations where people are under a lot of stress or tired from working a lot and are still required to work.

Some products are extremely dangerous, like construction explosives, or cars. And yet many people operate them safely for years without incident. Other people get themselves killed. That doesn't mean it's the manufacturer's fault if one of their customers decides to go to a bar and then get behind the wheel.

Conversely, some products are dangerous when used as directed, for example certain poisonous plants that herbal sociopaths will advise you to eat, which provides an obvious distinction with sharp objects whose manufacturers explicitly advise you not to stick your fingers in.

Having safety protocols doesn't matter if it's something deployed in situations where people are under a lot of stress or tired from working a lot and are still required to work.

It isn't the manufacturer that caused you to be stressed or tired or created any obligation for you to work under those conditions.

Ensuring safety requires us going beyond 'you should have followed the rules', you have to consider the whole context and all the facts.

Because that was the context of the post you replied to.

To turn your car example around, a ton of regulations exist for safety features in cars. Why not for table saws?

Regulation of this type generally falls into two categories.

The first is sensible new safety technologies that are in the process of being adopted by the market anyway. Legislators then race to mandate them so they can try to take credit for the resulting safety improvement that would have happened regardless.

The second is incumbents who have invented something weak and then discover that their "feature" is failing in the market because it's burdensome to use or isn't worth the cost, so they try to have it mandated.

Both of these are dumb. The second one is more dumb, but we can get a better understanding of how by noticing the problem with the first: It's mandating a particular technology. Now nobody can invent something better because better is different and different is prohibited.

It also eliminates nuance and context. For example, package delivery trucks are required to have seat belts like anything else. But the drivers don't use them, because they'd be getting in the truck, putting on the seat belt, driving ten feet to the next house and then taking it back off again. It would be better to design the vehicle to be driven while standing up and then use some alternate mechanism to restrain the driver in the event of a crash, like a padded barrier at the level of the driver's chest and waist which would still be in place even when the driver only expects to be in the vehicle for ten seconds. But that's not allowed, so the mandate precludes a passive safety feature in favor of a manual one that the drivers often don't use.

"The manufacturers can already be sued if they make a product which is dangerous even when used appropriately."

In most states they will get comparative negligence, if they get sued at all.

The traditional way of doing what i suggest is paying into a fund that people make claims against without having to sue.

As for the rest, yes, you can game it, but that's easy to fix as well - you can require they have sufficient assets/surety to cover if you sell in the US. This is done all the time.

It is quite easy to ensure a level playing field, and we know, because this is not the first situation something like this has occurred in.

Also note they already can't sell saws this dangerous in europe. Between losing the european market and the US market, there isn't a lot of market left.

Which only trades one cost for another, because now there is less checking going into ensuring that the person responsible is the person paying the claim. Why should innocent people have to pay more for tools to cover claims by other careless customers who injure themselves through their own negligence and no fault of the manufacturer?

you can require they have sufficient assets/surety to cover if you sell in the US.

And now nobody can start a small company making tools because they can't afford to post the bond.

this is not the first situation something like this has occurred in.

I've long been of the opinion that mandatory underwriting is superior to regulation for most things. At least: housing, medicine, and consumer products. Maybe not airplanes, but then again, maybe.

If a manufacturer of table saws was required to be underwritten for claims of injury, they'd find it in their best interest to make those saws as safe as practical.

This itself requires regulation: no skating out of it by having customers sign bullshit waivers, and of course some department would have to audit businesses to see to it that they're complying. But the sum of that is much less costly to taxpayers, and also avoids all the cost-disease which results from a regulatory regime whose interest is in producing paperwork, and which has no incentive to change, streamline, or remove a regulation, once it's in place.

My internal cyncism says we may as well end up with a regime similar to healthcare insurance in the US which puts a lot of the costs on consumers ahead of time, and is otherwise hidden – a scheme where, in theory, people often get compensated for horrific accidents, but where (a) the better the compensation you want, the higher the upfront cost (of the saw), and (b) the more horrific the (saw-related) accident and the higher the potential cost to the insurer (manufacturer), the more hoops the consumer will have to jump through to prove that their injuries were due to unavoidable injury/whatever the standard is for non-frivolous claims. There's "ideal" insurance, and there's insurance in pattern, practice, and procedure, and the US is the worst example of that.

There's every incentive for a jobsite to use the cheapest saws, and cross their fingers; there's every incentive for a manufacturer to make it as painful as possible to ask for compensation. Either way, if you're working for an el cheapo contractor on an entry-level wage, you're probably screwed.

It's a fair comment, but I want to note that insurance in business and insurance for individuals operate on a rather different basis. Insurance companies are better behaved when they know they have to be, and businesses as a class are able and willing to pursue their interests in court.

The great success story for underwriting is consumer electrical devices, where Underwriters Labs was responsible for many decades in which such devices didn't burn people's houses down. That's been undermined by lax global trade policies, I no longer even trust that a UL logo on something means UL was involved, it might easily have been added in China.

It's worth reading up on the organization if one hasn't already. It makes a good case that we need less regulation and mandatory, ubiquitous underwriting. https://en.wikipedia.org/wiki/UL_(safety_organization)

It's understandable that many people hear "we need less regulation" as "corporations should have more carte blanche to screw everyone over", but I sincerely believe this would both reduce friction and cost for business, and maintain or even improve the standards for safety and the environment which regulation is intended to provide.

For every dollar in job site saws sold, you cause ~$20 in injuries.

Fine.. but for every dollar in job site saws sold how much useful output do they produce? My suspicion is it's something like:

$1 for the saw. $20 for the injuries. $500 of added project value.

In which case, it's not at all clear that sawstop is a useful addition.

"Fine.. but for every dollar in job site saws sold how much useful output do they produce"

This is accounted for in the economic benefit calculation, and is estimated at somewhere around 650million-1billion total.

Even if you add sales + economic benefits, it's less than cost injuries.

The CPSC has done this analysis (3 times now), as have others, as part of the breakeven analysis.

Provided no new error modes are revealed, like overall reduction in safety due to over reliance on safety systems and their perceived infallibility even under prolonged conditions of zero maintenance.

Not that this has _ever_ happened before.

I would love if someone could chime in with actual statistics here, but I've always heard that table saws are the most dangerous common power tool in the US by raw injury count alone. I have a weak assumption that more people have circular saws than have table saws. This seems unsurprising to me, because both track and circular saws are used with the blades faced away from the person. I can't speak to track saws, but I've never had a board launched at me by a circular saw. People also tend to over-extend themselves over tablesaws, and have their hands inches from the blades.

I would love if someone could chime in with actual statistics here, but I've always heard that table saws are the most dangerous common power tool in the US by raw injury count alone.

I don't have data, but there are various threats with a table saw.

1. Overconfidence / complacency. Things like reaching across the blade, not using push sticks, etc.

2. Kickback. It happens because you pinch the workpiece between the blade and the fence. Knowing how to properly configure a fench, featherboards, and how to use the kerf and ribbing knife is important.

3. Shop clutter. People tripping and/or slipping around their saw.

SawStop style tech vastly improves most of these scenarios. Kickback, though, turns a workpiece into a very large projectile. Where you stand matters a lot.

To be clear: I was asking for data about relative frequencies of accidents with varying tools, not about risks from table saws.

But yes, those are all risks. Additionally, like most tools a poorly maintained table saw is more dangerous.

The table saw I grew up using was from the 1940s, so was about 50 years old by the time I started using it in the late 90s. Its fence was always around 1-3° out of alignment. Absolutely no safety features whatsoever. The motor was fairly weak too, and the surface was rough, so you needed to use a bit of force while cutting, which obviously increases the risk of slipping into the blade.

I got a SawStop last year for my new house's shop and was pleasantly surprised by how little force I needed to use to guide workpieces along it while cutting.

Sawstop prevents one specific mode of improper use, and it's not even the most common danger present with table saws: kickback.

No matter how good or experienced you are with a table saw, you will have it launch material like a projectile backwards at some point (kickback.) Don't be standing behind it when it happens - instead, be on the other side of the fence.

If you're on the safe side of the fence, you likely don't have enough arm length to comfortably cut your fingers off anyway. (And why weren't you using a push stick?)

and https://www.cpsc.gov/cgibin/neissquery/Data/Highlights/2022/...

for general data

For table saw vs band saw, NEISS tries to track table saw vs hand saw vs radial arm saw vs band saw vs powered hack saw vs ...

It's hard, obviously, since it depends on effective coding of at point of injury.

As of about a decade ago (i don't have access to later data):

78% of injuries are table saw

9% band saw

8% miter saw

5% radial arm saw

Circular saws and track saws would be in the "other powered saw" category, and accounts for less than 1% of injuries.

blade contact was 86% of the injuries

While this data is a decade old, the data trends have been relatively stable (even the track saw one)

The simple reason that track saws don't show up meaningfully is there aren't enough sold - these aren't sale-normalized numbers, and the number of track saws vs table saws sold appears to be about 100x difference.

The main trend is that radial arm saw decreases and goes to miter saw and table saw.

This happens naturally since there are not a lot of sales of radial arm saws anymore. (But also shows you how dangerous RAS are - despite them not really being sold, they are highly overrepresented in percent injuries)

I'm actually for this change, though normally I'm not a fan of trying to mandate the use of technology to solve social problems (like vehicles installing distraction sensors). The table saw manufactures are caught in a stalemate legally speaking, where adding a massive safety feature like this can be seen as a tacit admission that previous generations of saws are unsafe. This could lead to a massive (expensive) recall, like what happened with radial saws. This seems like the perfect example of when a government should step in and brake the local maxima to ensure better safety for its citizens.

If all this legislation does is push more people to use low-end track saws on foam, I think that's a huge safety win. In the shop, the only woodworking tool I'm more weary of than a table saw is a jointer. Interestingly both have large spinning blades on the surface of a large flat surface. I wonder if that design in general needs to go by the wayside?

Intuitively, the table saw seems more dangerous to me (and I'm typing this with a finger with three pins in it from a table saw injury) because you're manipulating the circular saw directly, and thus more consciously. With a table saw you're manipulating the workpiece into the blade, which is indirectly a threat--in my case, the wood kicked, knocking my finger into the blade.

I've seen jointer near-miss videos and the adult education woodworking class I took is even more terrifying in retrospect. I knew table saws were dangerous and assumed they were the most dangerous. At least with a table saw the fingers can often be reattached. Jointers and router tables just make hamburger.

I'm becoming a much bigger fan of mounting an uneven piece of wood to plywood and running it through the table saw to get that first edge.

The common theme is that when the blades catch the wood and the hand is gripping it, the hand tries to follow the wood. If you get very unlucky the wood escapes about the time your hand is nearing the blade and momentum carries you in. For routing tables it’s the curved pieces that’ll get ya. Snag, spin, bzzzt.

I believe my instructor suggested but didn’t mandate a two pusher technique with the jointer, where the left hand pushes the wood against the back plate and forward while the right helps stabilize. Less pressure on the hand with a vector toward the blade. Seemed safer to me.

I don’t understand how you can hurt yourself with a jointer (presuming you’re using a push stick and pad to push the wood down from the top).

I have seen videos without them, with people saying that they have older saws and that is how they are used to work. But not that they are useless. Especially not the riving knives. One interesting argument I have seen from someone: currently the recommended way is to have a blade just a tad bit over the top of the piece, but he was taught to have it much higher. His point was that in such set up there was more vertical pressure down from the blade rather then horizontal and thus lower risk of kickback. Not sure if his idea has merit, but interesting thought.

I think it is fair that a holistic analysis of the legislation would make a lot of sense. I would be surprised to know that changing a saw from 150 to 450 would be a major change in its use. But, I could be convinced that it is not worth it.

I will note that is also taking at face value the cost of implementing the tech. In ways I don't know that I grant. I remember when adding a camera to a car's license plate was several hundred dollars of added cost. And I greatly regret not having one on my older vehicle. Mandating those was absolutely the correct choice. My hunch is when all saws have the tech, the cost of implementing will surprisingly shrink.

I think you're on a reasonable path with your thinking there. Something I learned a couple of years ago is that table saws are particularly popular in the US. It varies from country to country, but in some places circular saws on tracks are the norm for the same purposes, especially on job sites.

These aren't very popular in the US so you don't see the dedicated "track saws" in stores here that are common in the UK for example. You can pretty easily buy a Kregg Accu-Cut which is a similar idea that you bolt onto your existing circular saw, but it's a little bit annoying compared to purpose-built track saws that are a tidier design and often plunge cut as well so it's simpler to start the cut. But you can also get proper track saws online, and I'll probably pick one up eventually to replace my Accu-Cut.

I don't think this is a perfect solution, getting cabinetry precision with a track saw might be tricky. But no one's doing that with a portable contractor table saw anyway. And the track saws are even more portable. I think the table saw concept is a better fit for larger, fixed tools, which I would guess probably have a better safety record than portables (larger table, cleaner environment, etc) even without sawstop technology. And I think it's more feasible to have good quality guards that will be less annoying on a fixed tool than a portable one, where they have a tendency to break off.

He also argues for riving knives and blade guards as an alternative, which are great, but not all cuts can be made with them in place.

I'm a fan of Stumpy Nubs but I disagree with his economic analysis here. Saw Stop has effectively had a monopoly on this type of saw, so of course they've been pricing it high. When Bosh came out with their own version it only made sense to price it at a comparable level to their only competitor. For them to massively undercut Saw Stop would leave money on the table.

There will be some cost in re-engineering the cheap saws to handle a sensor and brake. But those costs will be amortized over time and the materials themselves will be incredibly cheap. We're talking about a capacitive sensor and a chunk of sacrificial metal.

There will also probably be some cost saving innovation around the tech. Since Saw Stop is a premium brand coasting on patent-enforced monopoly they haven't had to invest in R&D the way Dewalt, Bosh, and Makita will.

It can trigger it yes, and it is destructive to the saw blade and safety device, and can ruin the clean cut of the piece, though may or may not ruin it entirely. Good saw blades aren't cheap, and neither is the safety device. I'm unsure of what wear and tear it has on the motor itself, they can at least endure a few triggers for certain and I doubt it's "good for it" but unless you're doing it frequently I also doubt it likely to ruin the device itself but admittedly am not sure about that.

And to be clear, it's well worth it IMO. Of all the tools I have in my shop, the Table Saw is easily the most dangerous. If I had long hair the Lathe would give it a good run for it's money though. I refuse to use a table saw without a sawstop (or similar safety break). The one I have and others I've used all have a key to insert to disable the safety device If need be.

My dad was a machinist when he was younger. My siblings and I grew up with a well-equipped home shop, including a table saw, a drill press, a milling machine, and my dad's pride and joy: a two ton metal lathe. He drilled into us the importance of safety for all the tools, but the most vivid lesson was the story about the drill press: When he began his apprenticeship, he noticed a large photo on the wall of the shop of a long pale stringy thing. He asked what it was. It was a tendon which had been yanked out of the arm of someone whose hand got caught in a drill press. I still think about that whenever I use a drill press.

The sawstop triggers when the blade contacts something conductive (like a finger), and needs to stop fast enough that when that happens the finger isn’t removed first.

It manages to do that within a few teeth, which is quite impressive at 1000+ RPM.

It does this by firing an explosive charge which shoves an aluminum block into the spinning blade, while dropping the blade below the level of the saw deck.

Essentially a type of airbag like braking action.

That is how it can turn s situation which would guaranteed an amputation into a minor scratch.

It can (and does) get easily triggered by things like conductive wood (pressure treated), nails or metal in the wood, metal coated plastic, etc.

Every workshop I’ve been at that has one has a collection of triggered/destroyed blades hanging on the wall.

It could undoubtably be done cheaper than it currently is ($30 a brake?) but as designed it’s destructive - and it’s hard to imagine a effective way to do what it does that isn’t destructive.

The brake is like $80-90 and contains a computer that collects telemetry. If it triggers for a reason other than user error you can send it in for a refund.

It doesn't drop the blade, just stops it cold (at least on the model I've used). The Bosch system dropped the blade (thereby avoiding destructive damage to the blade and brake) but they were cease-and-desisted by SawStop and unable to sell it in the US.

Yes, anything that can conduct electricity in the wood will trigger the safety device. Pressure treated wood is often so wet with copper based preservatives that it’ll trigger the safety circuit. Old nails in wood, your finger, hand, etc will also do this.

And yes in general the blade and brake are both trashed because of the wild deacceleration forces that happen instantly. Frustrating when pressure treated wood causes this, humbling when your hand caused it.

Never having used one of these before, is there anything (ideally conveniently built in) that you can use to know before you cut a particular material whether it'll trigger the stop? Touch it against the blade while it's not running and see whether an LED lights up, or similar?

There are LED indicator lights that flash red when it detects a current drop. When the blade is not moving, you can touch it with your finger to see. In theory you could do this with whatever material you're going to cut. If you're cutting metal, it's pretty obvious that you need to disable the brake system. Usually where it's iffy is pressure treated lumber. Sometimes it'll trigger, sometimes not. Really depends on the moisture content of the wood and that can vary greatly. "testing" by touching the material to the blade with your hands on it might or might not indicate that the brake would fire. The points you're contacting could just not be that wet.

Unfortunately there are lots of materials run through a table saw which can trigger a sawstop. A false positive destroys the blade. Decent blades cost several hundred dollars, and are intended to be resharpened and last for many years.

I belong to a community hobbyist workshop. There are a lot of rules, lockouts and a key in place around the table saw usage, but they won't install a sawstop because they can't afford to keep up with the wasted blades.

Personally, I think I'd rather have one, but I can absolutely see why people would disable them if they were mandatory.

Probably $9k with pretty good insurance, $17k-$20k with poor insurance (but nb the math on the good insurance probably works out such that you’re paying very close to that difference for sure every single year, in premiums)

Plus tens of hours arguing with provider billing departments and insurance. You’ll pay over what should be your max if you screw any of that up. Time lost and stress and confusion over sorting out new bills still showing up in the mail two full years after treatment was performed.

Also it’ll be a lot worse if you lose your job after.

If you don’t have insurance, you’re getting it patched up at the ER “for free” (you’ll be declaring bankruptcy soon) but not getting most of the follow-up work done. Even if your arm could be made right, it won’t be. Good luck with the nightmare of getting and maintaining disability pay-outs.

Oh and double the out of pocket costs if treatment spans two billing-years.

A closer comparison would be car airbags, but a type of airbag that has false-positives and deploys when the operator drives on a particular type of road surface, in which case the manufacturer calls it "user error" and tells the operator to disable it for that type of road surface. The road surface might appear the same to the operator, so needs to be tested carefully with special equipment before the car is driven on it. And since the active safety system is disabled for this surface, the operator has now paid for a safety system they cannot use, due to manufacturer incompetence

"It's just one additional requirement; it won't break the bank"....this logic, applied over and over by building construction regulators for the past few decades, is an underappreciated but important contributor to the housing affordability crisis.

Most of the building codes were written in blood - either that of the construction crew (in the case of site safety regulations) or that of the eventual owner (in the case of fire standards and suchlike). In both cases, long term costs should be reduced - lower insurance for developer and owner, less rebuilding burnt out shells, less earthquake damage, etc.

The regulations that weren't written in blood generally fall into the "zoning" discussion. Stuff like parking minimums, set-backs, etc.

The only thing I can think of off the top of my head that straddles the line is the requirement to have two staircases in low-rise apartment buildings. This is a uniquely (US)American code. Nominally to manage fire risk. But much of Europe and Canada manage with one staircase and improvements in building materials that reduce the risk of a fire starting before fast egress is necessary.

In every single place where housing is "unaffordable", a literal empty plot of land is also unaffordable. It has very little to do with what it costs to build a tiny shed. This is also why "tiny houses" and "3D printed houses" are nonsense and have done nothing to improve the situation.

The problem has nothing to do with the fact that the outlet next to the bathroom sink requires a GFCI device, or that you need a separate flue for your pellet stove, and everything to do with a small plot of land being a couple hundred thousand dollars despite literally being a forest.

The homeless aren't being kicked out/arrested because their tents aren't up to code, they are being kicked out/arrested because they do not have a plot of land they are legally allowed to pitch that tent on.

1. stripper - gets people into the showroom because of the low price

2. luxury - for the people who are not price sensitive and just want the best. This generates a lot of profit with little added cost to manufacture

3. medium - people see the stripper and upgrade to the medium, but aren't interested in the luxury price. This is where the bulk of the sales and profits come from

Which is a point frequently raised by those not supporting this regulatory action - will this cause the base price of a saw to skyrocket beyond what average individuals can afford?

My guess is probably not. The brake cartridge is roughly a hundred bucks, retail. The sensor system can’t possibly be more than a hundred bucks. And there will have to be some quality improvements to the rest of the saw in order to be better withstand the crazy decceleration forces. The bottom end of saws will proportionally be more expensive, but even this will quickly race to the bottom.

Which is anecdotally true, but hard to accept with the actual data of 30k injuries a year. So it's not a question of _if_ there's a cost to society here, it's a question of _where_ we put the cost: up-front on prevention, or in response to injury in the healthcare system.

Holy shit, is that verbal diarrhea written by ChatGPT or something? It's multiple pages of talking in circles, in the end it doesn't provide anything other than an unsourced assertion. This is how you get your information?

But no, they're not illegal. The actual directive governing that is MD 2006/42/EC[1].

The reason for why you don't see them in the EU are probably twofold:

1. That directive mandates a stopping time for the blade which wouldn't be possible with the same saw with a dado blade, a dado stack has more inertia.

Therefore saw manufacturers cut the arbor short so they don't need to deal with accommodating and certifying that fringe use-case.

But you're perfectly free to import a saw that can do this yourself, or modify and use an existing saw, or even start a niche "dado saws with EU stopping times" manufacturer.

2. There's a lot of difference in everyday life between the EU and US that don't come down to someone banning something.

That directive is from 2006, dado stacks weren't in wide use before that either.

I'm fairly sure that the reason this is a thing in the US is because of the relatively wide availability of table saws. I think most people over here wouldn't think to modify a saw for this task, they'd use a router.

Lacerations are the most common form of injury. Counting "bulk injuries" is not a particularly useful way to improve "safety."

_if_ there's a cost to society here

The question you really want to ask is "is the risk:reward ratio sensible?" People aren't using saws for entertainment, they are using to produce actual physical products, that presumptively have some utility value and should be considered in terms of their _benefit_ to society.

it's a question of _where_ we put the cost

With the owner of the saw. If you don't want saw injuries, don't buy a saw, most people don't actually need one. I fail to see this as a social problem.

if it means the insurance market won't have to bear several thousand for an injury?

Shouldn't owners of saws just pay more in premiums? Why should the "market" bear the costs? Isn't "underwriting" precisely designed to solve this exact issue?

I'd say yes.

With a yearly injury rate of 1:10,000 across the entire population? I'd have to say, obviously not, you're far more likely to do harm than you are to improve outcomes.

You're painting a hyperbolic narrative here and there's not a lot of evidence that this is the norm or the root cause of even a simple majority of the 30,000 incidents per year.

You're going from safety releases on exterior doors in the same breath to child labor? It genuinely makes me wonder if you've spent much time in places where manual labor with saws are done. In most of these places, the "apprentice" owns his own tools, and works as a sub contractor because that pay structure is ideal for them.

If you want to mandate that employers who own a saw that is used by shift workers must have some sort of safety technology, I think you'll be disappointed to find that these regulations already exist, and it's unlikely that "sawstop" technology is going to benefit these locations at all. They already have a more abstract set of rules that's more comprehensive and compliance is driven by worker complaints and fines.

Finally, it should be an obvious coincidence to everyone that we only outlawed child labor once gasoline engines were well developed and prevalent. Our social reasoning that "children just shouldn't work" isn't as simple as everyone presumes it to be.

Some might care deeply about the safety of their employees. Most don't do anything that isn't enforced by law.

Here every constructions site by law must have all staff wear high-vis vests, hearing protection, helmets, steel-toed boots, and so forth.

YouTube is filled with videos of workers in Pakistan using the "safety squint" when welding for eye protection, or using a moist rag as their lung protection.

This is the reality versus abstract bullshit arguments.

Additional profits aren't used to pay his workers above what the other shops do.

Are you... kidding?

First of all, let's say in this hypothetical perfectly efficient job market, a junior apprentice receives an extra $100 compensation annually because his workplace saved $500 on a circular saw that year and have five employees.

Do you think $100 is a fair price for your fingers?

We can meet up. I'll give you $100 in cash. I get to remove the fingers from one of your hands. You get to choose which hand. Deal?

Alternatively: Before accepting a work placement, do you personally spend several days evaluating the safety of that workplace? Do you check the fire escape? The smoke alarms? The material used for the carpets? Do you then adjust the contract if you find that the work environment is not up to your standards?

No, seriously, have you ever done literally this? If not, why would you expect any young, junior, desperate-for-a-job kid to factor any of this into any decision?

In most of these places, the "apprentice" owns his own tools

I've never heard of an apprentice bringing their own circular saw (a huge table!) to a workshop. Clearly you've never been anywhere near an industrial workshop yourself.

I hope they find a way to bring costs down. It seems like a very hard problem - you seem to need fairly high quality materials for the braking system to not bust up the machine itself, and the circuitry is a non trivial expense.

But if folks can't buy a $100-200 table saw, and they can't afford anything higher, then ideas like affixing a circular saw in an upside-down jig might start to become more common. And then they'd lose the baseline safety features of even a cheap table saw, such as the blade guard and riving knife, which might be even worse for overall injuries.

We mandate safety features on plenty of dangerous machinery, most importantly cars - seatbelts, airbags, brake anti-locks, lane-keeper assists... or we ban stuff entirely, even if it is completely safe to use when one has the proper equipment and knowledge like asbestos.

The key thing is 30.000 accidents a year. Each of these probably costs society around 50k, and that's just the medical cost, not to account for (permanent) loss or reduction of income.

I agree that some will rig up completely unsafe "alternatives" but honestly, doing that rather than renting a safe saw for a dozen bucks... those people at least know of the danger.

This will kill off the cheap table saw. It will be interesting to see how the hobby and industry adapt to $700 being the bar to entry — and that would be RYOBI grade stuff. The added cost isn’t from the mechanism, the cost is from needing to build a real frame around the blade instead of plastic and thin aluminum. The SawStop trigger is incredibly violent, the braking force will sheer the carbide tips off the saw blade from inertia alone. Cheap saws are almost all plastic and would be horribly deformed after a trigger.

I anticipate a return of something that used to be more common, the upside-down circular saw bolted to a table top.

The Consumer Product Safety Commission says that when a person is hospitalized, the societal cost per table saw injury exceeds $500,000 when you also factor in loss of income and pain and suffering.

Seems fishy[0][1], so I checked the study:

Overall, medical costs and work losses account for about 30 percent of these costs, or about $1.2 billion. The intangible costs associated with pain and suffering account for the remaining 70 percent of injury costs.

So the actual cost of each injury which results in hospitalization is (allegedly) $150,000, and they only get to the $500,000 figure by adding $350,000 in intangible "costs" tacked on. Totally legit.

Because of the substantial societal costs attributable to blade-contact injuries, and the expected high rate of effectiveness of the proposed requirement in preventing blade-contact injuries, the estimated net benefits (i.e. benefits minus costs) for the market as a whole averaged $1,500 to $4,000 per saw.

There is no cost to the regulation, but rather a "net benefit", because the cost (in real dollars) of the saw-stop devices is more than offset by the savings (in intangible pain-and-suffering-dollars)! Based on this obviously, intentionally misleading "math", they include this canard in the summary:

The Commission estimates that the proposed rule's aggregate net benefits on an annual basis could range from about $625 million to about $2,300 million.

Did you catch that? They didn't include so much as a hint that these dollar savings are, in fact, not dollars, but pain in suffering, measured in dollars!

In this life, only three things are certain: death, taxes, and being lied to by the United States federal government.

There's nothing dishonest about it. If you want to measure something, you need to pick a unit. For many people with serious injuries, and especially disfiguring or life-altering injuries, the hospital bill is an afterthought in terms of impact.

You're not point out a lie, you're pointing out that there's no direct conversion between dollars and happiness.

Choosing to re-define a word (like 'dollar') to mean something other than its actual meaning is perfectly fine, so long as you take care to inform the reader whenever you employ your nonstandard definition.

If you do not take care to make this distinction, then you are putting a false idea in another person's mind, which is, by definition, deception.

If you intentionally use your bespoke definition of 'dollar' to communicate about pain and suffering, refusing to define it (as the author of the paper did in the summary), while knowing full well that the reader will assume you mean actual dollars, then you are lying.

For many people with serious injuries, and especially disfiguring or life-altering injuries, the hospital bill is an afterthought in terms of impact.

That's a noble goal. Yet the only clear and honest way to communicate human suffering is in human terms, not in dollars and cents. Laundering that suffering into "per-unit economic benefits" adds zero clarity to the issue of suffering. It adds zero urgency. All it adds is a likelihood of misunderstanding, which is clearly the point.

There’s nothing misleading in the study, because they very clearly state the methodology for intangibles, and even provide an alternate calculation excluding it:

Finally, net benefits were significantly reduced when benefits were limited to the reduction in economic losses associated with medical costs and work losses, excluding the intangible costs associated with pain and suffering

…although net benefits appear to have remained positive using a 3 percent discount rate, benefits were generally comparable to costs when a 7 percent discount rate was applied.

I'll forever remain skeptical of SawStop. I understand their mechanism works quite well and they sell a very high quality saw, but I will never in my life buy it.

It's amazing how the discourse online has shifted. SawStop's original focus after having their patent granted was super-litigious IP-troll type behavior. They were able to win some cases and force other manufactures like Bosch to remove alternative safety they had engineered to compete. SawStop was lobbying heavily for a regulatory requirement to mandate their patented technology be installed on all table saws.

The online opinion of them was ... not good. Look up the old SawStop stuff on Slashdot if you want to see it.

Now that their patent is about to expire, it's "oh look we have changed" -- they haven't. It's just a desperate bid to get themselves insinuated in front of manufacturers who will be suddenly charged with a mandate to ship safety devices -- and of course SawStop will be there with the business shortcut. Sorry, no. Fuck them. Let the patent expire.

Don't like it. There are systemic problems with nanny-state thinking - you either solve all cases of danger at once, or you make the problem worse.

I was close to a story recently about a kid in a climbing gym who mistied their harness. Competent climber, but got careless and no one caught the faulty safety loop and they fell 40 feet on descent. Nothing broken, in a turn of miracle, but could have been fatal for them and others had there been someone underneath at the time.

Now, I'm sure that this will garner some conversation, but IMO this is an example of the Safe Playground Effect; that is, because we put soft corners on everything we deem to be risky, we implicitly teach people that the world has been made safe for them. Without the risk of mild harm (on the playground) we don't develop the sense to be cautious with major harm (like at the climbing gym). The unconscious, innate instinct is "it can't be that bad, I've existed for X years sort of carelessly and I've never gotten hurt".

Problematically, this is the sort of effect that is nearly impossible to analyze with any reliability. Too many connected, confounding factors even in the most controlled environments. I think it's fairly intuitive, but there's a lot of room for me to be wrong and I'd be the first to admit it.

IF this is the case, however, then what we are effectively doing by adding these mandated safety measures piecemeal, is lowering the personal shelf of responsibility whilst leaving other risks at the same level of probability and effect, making them that much worse because now people as a whole are less vigilant re: their own safety.

One actual example I can think of to back this stuff up is the Burning Man festival. It's a city of 75,000 with precious little in the way of medical resources in an extreme climate peppered with dangerous art made of metal and splintered wood and fire, and yet the injury rate is far lower than that of a normal municipality of the same size (in the past decade, there have been 2 fatalities IIRC, which is way lower than the national average per pop.) My (admittedly hand-wavy) guess about the why is this: people who go there know that there are risks, and despite being largely chemically altered this awareness translates to a lower risk of injury even considering the added risk factors.

But, you know, that's just like, my opinion, man.

I must confess to spending quite a bit of time thinking about these sorts of things - the stuff that’s invisible to our current modalities of analysis. There’s probably something a little pathological about it.

Another example of making it harder to produce one unit of economic output (a saw, in this case). When we make it harder to produce things, we will have less of them, or less of something else if we re-direct our efforts from something else.

It's death by a thousand cuts this way, as our overall economic productivity slows.

In the current world, people have a choice to purchase a saw that took more effort to produce, if they think that it's worth it for the additional safety it provides. This new law would eliminate that choice, and those who don't think it's worth it will have to purchase the high-effort saw or go without.

NPR article from 2017 on this, "Despite Proven Technology, Attempts To Make Table Saws Safer Drag On":

* https://www.npr.org/2017/08/10/542474093/despite-proven-tech...

Per above, the way SawStop® works:

Gass is a physicist and he designed a saw that could tell the difference between when it was cutting wood and the instant it started cutting a human finger or hand. The technology is beautiful in its simplicity: Wood doesn't conduct electricity, but you do. Humans are made up mostly of salty water — a great conductor.

Gass induced a very weak electrical current onto the blade of the saw. He put an inexpensive little sensing device inside it. And if the saw nicks a finger, within 3/1000ths of a second, it fires a brake that stops the blade. Gass demonstrates this in an epic video using a hot dog in place of a finger. The blade looks like it just vanishes into the table.

Unless they commit to releasing their full patent portfolio in favor of this effort, it seems like the legislation vastly favors an economically motivated actor, which rubs me the wrong way.

I can see some potential issues with this:

1) Patents. The article goes into this a bit -- supposedly the folks behind SawStop have said they'd open up a key patent, but I wouldn't want the U.S. government to mandate this without reading all the fine print and making sure that this can't be used by SawStop to crush all their competitors.

2) Materials. I often cut aluminum on my table saw, using a non-ferrous metal cutting blade. (It works fine for wood too.) As I understand it, SawStops are activated when they detect high conductivity materials. How does this work for cutting metals?

3) False positives, repair costs. Replacing the blade periodically due to accidentally cutting wood with slightly-too-high moisture content would get tiresome. (For that matter, so would putting off a project for months if I have to wait for the wood to dry out.)

I'm generally in favor of safer tools, but it seems like there are some significant trade-offs involved here.

Steve Gass, a patent attorney and amateur woodworker with a doctorate in physics, came up with the idea for SawStop's braking system in 1999. It took Gass two weeks to complete the design, and a third week to build a prototype based on a "$200 secondhand table saw." After numerous tests using a hot dog as a finger-analog, in spring 2000, Gass conducted the first test with a real human finger: he applied Novocain to his left ring finger, and after two false starts, he placed his finger into the teeth of a whirring saw blade. The blade stopped as designed, and although it "hurt like the dickens and bled a lot," his finger remained intact.

I don't know where to stand on this one.

I've got a table saw. The extent of my training on how to use it was my design tech teacher saying very clearly that none of us were ever to use it and some YouTube video of dubious information content. I bought it from Amazon, nothing approximating a check that I had any idea what to do with it.

I am very frightened of it and thus far only slightly injured. An automated stop thing would make me much less frightened. Possibly more frequently injured as a direct result.

Having the option to buy a more expensive saw which slags itself instead of your finger is a good thing. Making the ones without that feature illegal is less obvious. I think I'd bolt a circular saw under a table if that came to pass.

A gunpowder charge shoving a piece of aluminium into the blade on a handheld circular saw would be pretty lethal in itself. Lots of angular momentum there - jam the blade and the whole thing is going to spin.

It seems dubious that I can buy things like circular saws and angle grinders without anything along the lines of some training course first. That angle grinder definitely tries to kill me on occasion. That might be a better path to decreasing injuries.

I take it that simply dropping the saw (and then braking it afterward) is not fast enough to reduce injury?

I saw a demo of another safety saw, which was using very sophisticated monitoring systems. It was essentially dropping the saw if it detected the hand getting too close to the blade.

Saw Stop waits for contact. So the detector system has more time to move the saw out of the way, than the Saw Stop does.

I guess having to move the blade and the motor is too much energy, even or particularly, if its spring loaded, compared to springing the jamming piece that Saw Stop uses.

As much as I would love to see this kind of tech added, our current “greed is good” economic climate that is eviscerating the 99% will mean that this change will disenfranchise most who would have gotten such a saw. Sawstop isn’t going to open up their patents like Volvo did out of the goodness of their heart. Those patents will be monetized to the hilt, to extract maximum possible revenue from the consumer.

The only reason why I even have a table saw is because of a convergence of events: renos on the apartment to make it more saleable, better job with more income, Bosch putting out a new model such that the old model had steep clearance pricing, and so forth.

Had that table saw cost even $100 more, I would have been doing the work with wildly inappropriate tools that likely would have made the work even more dangerous. Or used an old, pre-owned, beat-up tool that could have malfunctioned in dangerous ways, or have had safety features removed by the prior owner.

Yes, let’s implement that law. But let’s also force SawStop to pull a Volvo, especially if they aren’t working in good faith. They have already been compensated by that product many times over, it’s just a cash cow at this point. And the public interest must always come before profit. Not remuneration and RoI -- profit.

So here's the problem: you can buy an older cast-iron table saw with good precision and a large bed for $50-$150 on craigslist, or you can buy a cheap piece of made-in-china plastic at home depot for $500. The cheap piece of plastic checks off more safety features from a regulatory standpoint, but tiny size and poor tolerances results in more kick-back and accidents.

My two bits as a carpenter w/18yrs table saw experience -- there are plenty of safe ways to use a tablesaw, fingers nowhere near the blade. SawStop's trip randomly, and the saw itself just sucks to use, its a bad design top to bottom. And you still have to let the operator disable it at their will.

If they are so dangerous, then make it licensed and mandate training, which is really what makes saws unsafe -- the untrained.

That's funny, I was just thinking about how affordable things are nowadays; we should really make them pricier.

A good idea on paper, marred by reality

First, this would basically grant Sawstop a monopoly. They say they'll release the patent, but I'd like to see that requirement built into the bill

Second, it doesn't seem to allow for alternative safety systems. Bosch has a system that competes with Sawstop, and is arguably better, as it doesn't destroy the saw, blade, or carriage, but is currently unavailable in the US due to Sawstop parents

If the bill were to allow for the Bosch or other systems on us soil then I'd have far fewer qualms over it

I just bought a job site table saw for some home improvement projects. I’m so friggin wary of it. Bought all the safety upgrades I could find. Nice push sticks. Micro jig gripper blocks, feather boards. Try to run the guard at all times as well.

I get the opposition, but this is a huge savings in the long run, both in terms of sheer money, and pain and suffering. The math on table saws is staggering (as pointed out in this comment section.) It's hard to stomach allowing several amputations a day to save people $50-100. I know a table saw is as safe as the user; I am so terrified of mine that it's probably commercial air travel level of safe. But stats have consistently shown the average user isn't, and there's no reason to expect that to change.

I think we can expect added costs to come down a lot when every table saw has one. They will be more expensive than they are now, for sure, but I don't think it'll be 3x. And I'm not worried about beginners being unable to afford one. There's a thriving used table saw market that'll still happily amputate your digits, these things live forever. You'll be able to get one of those really cheap when every new table saw also has anti-mangling tech built in, as nobody but the knuckle draggers will want the old ones. In fact I'd expect a flood of people (myself included) selling their crappy old table saw without brakes for the first affordable table saw with them.

And if you just really don't like your limbs, I saw a radial arm saw at Menard's for pretty cheap.

I'm in the UK, I used a tablesaw professionally for some years, often in very basic circumstances. I have never ever come close to an accident with a tablesaw. The reason:

1) UK tablesaws all come with a top-guard and a riving-knife fitted. The riving knife stops the timber from closing on the back of the blade, causing a kick back. In many designs it also holds the top guard up.

2) During my apprenticeship training there was a mandatory table saw course. We were taught how to set the guards and safely use the machine.

3) a riving knife based guard gets in the way of cutting grooves and rebates. If you take it off to do this then you replace it with a guard or jig to keep it safe. Then you put it straight back on.

4) I sometimes watch American 'makers' on YouTube and they terrify me with their working practice. My hands never went closer than the edge of the saw table. I used push sticks and jigs to handle everything close to the blade

5) I have never seen a sawstop over here, and it looks like a stupid hitech solution to a problem better solved by guards.

This will be lost now in the conversation, but this video by woodworker Stumpy Nubs is worth watching for key context: https://www.youtube.com/watch?v=nxKkuDduYLk

Yes SawStop sued Bosch for patent infringement and won. But they also then immediately offered to allow Bosch to have a license for free to continue distributing in the US. In the safety commission meeting,they also annouced they would not puruse any lawsuits for the key technology still under patent if the rule was passed.

Does this fully address the potential cost issues for beginning woodworkers? No but I very much think the video is worth a watch to make a more nuanced judgement.

SS wants this to become a requirement because it elevates the cost of all table saws up towards their entry level gear. Their cheapest saw is $899, when you can get a comparable saw (sans flesh sensing tech) for around $499. If their competition now has to sell a saw at $899 (less licensing fee to SS), then they'll be at a competitive disadvantage since now the pricing floor has been lifted up to SS's level. And you know SS will be advertising that they invented this tech, blah blah blah.

SS is acting in their own interests, or they never would have used the patent system to prohibit this technology.

I'm all for the Saw Stop, and I wouldn't use a table saw without one. (I prefer not to use table saws at all now!)

However, I'm pretty sure than the vast majority of the pressure to mandate the "Saw Stop" comes from the "Saw Stop" corporation, who hold exclusive rights.

I survived a childhood regularly using a radial arm saw. My dad was very clear I was not old enough to use it until I was 12, and then we did a full afternoon of what the proper way to use it and how to get hurt using it.

These are literal power tools with spinning blades of death. You shouldn't use these without training and you should understand how you get hurt on one of these. I see this as government overreach yet again. I'd only be ok with this if the requirement has an expiration date so that way it doesn't block future innovation.

My dad has three "pointy" (meaning the corners got cut off) fingers on his right hand, and at least on his left, courtesy of tablesaws. At the very least this technology should be mandated for the large non-portable saws like you find in most commercial wood shops. I'm glad to see action being taken on this finally.

Damn SawStop. You create a product that you can not only lobby the government into forcing people to use, but activating it destroys not only the SawStop but also the saw blade, necessitating replacing two products. What a perfect grift.

An acquaintance of mine was a professional carpenter for a theater company. Thoughtful, careful guy. Never in a rush. He of course used a table saw all the time. I asked if he had Sawstop. They were too cheap.

He still has no idea what happened, he simply came to holding the bleeding stumps of his fingers. Surgeons managed to reassemble some functioning digits out of the chunks.

It is my opinion that the government should purchase and "open source" safety patents as they come up, then manufacture replaceable safety parts to sell at cost.

Here's the first thing I noticed when I just looked up SawStop. They have a reasonable saw for $2k, in the same "class" as my 1970s Sears, based solely on size. And not all that much more expensive than other brands.

Looking at the picture, the saw is safer than mine even without the brake, because of the quality of the fence and other fittings. Unfortunately, a mandate won't get saws like mine out of circulation.

What's keeping me from going right out and getting a new saw is that mine is only used sporadically, and is mainly a "horizontal surface" in my garage. I'm done with the big projects that made my house livable.

My safety rule for now (this is not professional advice) is that I don't attempt tricky cuts at all. The biggest risk I've noticed is trying to hold onto a workpiece that's too small, and I'd rather just scrap it and use longer stock. My hands are never closer than several inches away from the blade. And I have other tools for other jobs, such as a chop saw, so I don't try to do "everything" with the table saw.

I see so many videos of (predominantly USA) carpenters using table saws without even the bare minimum of safety features (even just a riving knife, for example). Is there no way to just enforce basic low-cost low-effort safety features rather than just jumping all the way to a very costly commercial saw-stop-like solution?

The US Government doesn't give a damn about safety, the individuals who pass these laws have money at stake. Hence the financial windfalls that come to all the Reps in the House that just happen to sit on specific committees that oversee certain agencies which promulgate rules which have no real basis in law, but sure help them make money off building barriers to entry and functional mono/duopolies.

It's long past time for peaceful revolution.

If I'm understanding this correctly, the problem here is other saw companies aren't implementing a safety feature because SawStop has a patent on the relevant technology. Now the US federal government wants to make that safety feature a requirement and SawStop pinky swears to release the patent.

Why don't they just strike down SawStop's patent on the technology instead? Bosch apparently already tried to implement the tech but was scared away by SawStop's lawyers. There's a proven interest in the tech from other industry players. Is there any evidence that the proposed regulation is even necessary?

Seems ridiculous to me that they'd even allow a company to prevent other companies from implementing safety features in the first place.

I can't support any business that tries to make their product mandatory. Someone says here he's not scum, he is absolutely delusional scum. Does anyone else think having the government mandate what you can buy is a good idea? Another company designed a saw which did the same thing and which didn't destroy a $200 cartridge and the blade. He said he'd sue them into oblivion. He's a greedy prick who would see people maimed before he'd give up the profits on his half-assed, shitty, Chinese made trash. Use a blade guard, ffs. Don't support this asshole.

When sawstop engages it destroys the blade and ruins the stop cartridge. So you need a new cartridge and a new blade, which is better than a finger but not cost free. Wet (damp) wood, aluminum, and any other material that is a bit conductive can trigger the sawstop. However sawstop has a bypass mode, which allows you to cut conductive items (and your finger).

This article is pretty aggressive with this statement “ Woodworking has been a nearly lifelong passion for Noffsinger, and he was no stranger to power tools. Back before his accident, he'd seen a demonstration of a new and much safer type of table saw at a local woodworking store. Marketed under the name SawStop, it was designed to stop and retract the spinning blade within a few milliseconds of making contact with flesh — fast enough to turn a potentially life-changing injury into little more than a scratch. Noffsinger's table saw wasn't equipped with the high-tech safety feature because manufacturers aren't required to include it.”

Actually his saw wasn’t equipped with sawstop because he chose not to equip it. He knew of its existence, it’s readily available (online and also at Lee valley tools), but he chose not to get the safety device and somehow that’s the manufacturers fault? Cmon man. This same jerk will be the guy who buys the thing, turns on bypass mode, cuts his finger off and sues the manufacturer.

We don’t need safety devices mandated on personal table saws. Maybe osha should require saws on jobsites to be retrofitted with saw stop to protect workers, but it is most certainly not the manufacturers fault if you cut off your thumb. I suppose chain saws and motorcycles should just be straight illegal then ?
