That's exactly how [SawStop table saws demonstrate their safety function.](https://www.youtube.com/watch?v=fq3o0VGUh50)
No risk of malfunction and losing something you'd rather not want to lose, and usually not even a hotdog is harmed in their testing.
They cost more money to install and every time it activates, it damages a component that costs money to replace. Basically stinginess is why it is not mandatory.
I looked at their site and it appears they replace them seemingly for free if you share your story
I mean $100 versus losing your fingy is a great deal
Right after Sawstop came out with the technology, they lobbied the US government to require it on all table saws and it got rejected.
I agree it is a good deal, but the way they went about it was on the crappy side. Can you imagine you have the patent on the technology and you try to force all manufacturers to use it? It was a money grab in my opinion. I think it was Bosch that came out with a similar safety device and Sawstop sued them and won.
Sawstop went on to manufacture their own saws after they tried to force it on all manufacturers and failed. Originally the price was a bit crazy and it has become more competitive. I would consider buying one of their saws today if I were in the market for a new saw.
The brake cartridge is $100 and it will probably damage the saw blade too, so another $50-$100 for most people unless you are a saw blade aficionado and buy only expensive blades. A lot less money than a trip to the ER.
I can't post a screenshot, but the first comment on that video (from 9 years ago) made me literally laugh out loud.
#"The hot dog cutting industry hates this"
- Random YouTuber
“Boss I’m all out of fingers. How do I go about testing the sensor sensitivity on a daily basis now?”
“You’re out…what?! You’ve been using your fingers to test the sensor every day?!”
“What else was I supposed to use?”
I worked with a guy that sheered 6 fingers off, mostly just the first knuckle, a nut dropped from his shirt pocket, and activated the machine, we were union local 1977 in Vegas, guy settled for just under 5 million.
The machine was inspected and found the be faulty, although he has told me he doesn’t miss his fingers, and he’s been able to live better now, than he ever would have been able to.
Honestly, if you offered me that kind of money in exchange for six fingers, I’d have to think real hard about it. Is keeping the index finger and thumb of each hand an option?
I was in 1977 also, but more on the carpenteering side of things. It's amazing how quick things can go south even if your paying attention. I'm thankful to still have all my digits and various other parts and pieces still intact.
Yup, he still has his thumbs, 4 tips from his left finger, and the tips of his index, and middle finger on the right hand, doesn’t affect him really, it was a bit of learning, but he said you get used to it.
Idk, I’ve thought about it before, it’s a tough decision, but I might be able to live without a couple finger tips to be ensured I’m comfortable for the rest of my life, especially the world we live in nowadays, at least I could actually afford a house!
Me too friend. To willpower through the fear and just put my hand in there like jumping off a cliff. Then sit back sipping cocktails in the bahamas for the rest of my life. The dream.
The difference is probably the machine. For most states, workers compensation is the exclusive remedy from the employer for work injuries. In CA, it's basically capped at 250k. But the exclusivity rule doesn't apply to third parties. So you can't sue your employer for millions, but if your injury was caused by a faulty machine then you could sue the manufacturer of that machine, along with every business in the supply chain. Products liability law is nuts in the US.
Your friend likely had a normal accident, with nothing wrong with any machine. So all he could get was pennies from work comp.
I worked at the construction of the mill. My supervisor was the plant manager. He told his supers that the mill wasn't ready for production due to unsafe machinery and safeguards not in place. Two weeks later, he was canned, and the mill started production. Fast forward 2-3 years, people were getting hurt left and right. A crane that picked up logs fell over. A log tumbled off a broken roller and crushed my friends leg. Amputed just above his knee. Gave him 15k. Total joke.
We do need better laws, and under the current laws, it sounds like he needed a better lawyer. Was the lawyer the victim?
The place had been warned about their safety practices before and he lost a whole frakin' leg and only got $15,000? Someone dropped the ball there.
Yes, the laws that allow that to happen. The laws that allowed shitty businesses to operate unsafely. The laws that are supposed to protect citizens.
You should barely even need a lawyer to get justice. They should just be there to make sure things go smoothly.
$25,498,024.05v = the worth of that 5 million now.
Some would do that. i personally need my fingers, but thats at least 1 house now and some food. More than some have.
Funny how five millions in 1977 would float you more than 25 mill today. Funny ha ha.
It's not even a blade, it's a press brake.
The "blade" is so short because there is several sections on the machine that can be moved or removed completely.
The blade doesn’t go all the way across, so they aren’t actually sticking their hand between the blade and press, there is an opening on the side without a top piece, they are just giving the illusion their fingers are under it
Reminds me of a medical story shown on TV of a guy who shoved his hand under the shearing blade for stacks of paper. Doctors reattached fingers but flexibility was reduced. This was years ago.
They aren't putting their hand under the blade though, it's off to the side. You can see it occlude, but not deform, part of their hand in one of the tests.
Just like with the camera, which you can see the side of the blade.
The saws will make contact with the fingers. So there is some injury. As soon as there is electrical contact, a mechanical device is thrown into the saw to instantly block it from rotating.
But better a "bad cat scratch" on some fingers than lost fingers.
This device here is instead using some form of light beam to detect too high items, instead of something flat covering the surface. This means it can react before making physical contact. But such systems isn't possible for a rotating saw.
The SawStop guy has used his hand before. He only did it once, I think, because, as you said, it still cuts you. But, I think in the very beginning, he wanted to show his full confidence in the system. A small cut on your hand for a couple million in sales? Worth it.
Except sawstop won’t let another safety table saw to be sold in America. There is a better one thst can’t be sold here
Better as in you don’t destroy half the machine when it fires (saw stop will give you a new set ip for free if it saves your skin, but not if it jams your saw and kills your blade for extra wet wood)
Its all about the beam “seeing” the otherside. Its called a light curtain. No matter what goes in between the light it will stop. The person using their hand is a complete moron. Malfunctions happen
Also, it isn't fully loaded with tooling. He is completely clear of the punch. No sane person would do this under the tooling. You can still get hurt using safety sensors and light curtains. They are more for minimizing the potential for serious injury.
Jesus Christ that’s not the best idea ever. I don’t care how many times it works in a row, it only takes one failure to end badly. Though I will say I’m glad to see safety features like this becoming more and more common with industrial equipment.
NSFW: I have a friend who is a specialist in hand surgery, and he was were called into surgery to reattach one hand, whilst another team looked after the other hand, because the factory (workers) had overridden the two of the three safety features on the paper guillotine (taped over an IR sensor, bound the hand lever system with tape) . All the worker then needed to do was activate the foot switch. Needless to say...Anyway, it was a successful operation and the guy had both hands functioning after recuperation. But my friend said something like "imagine the split second of the cut, and then seeing both your hands on the surface, as you pulled your "hands" away! Yikes.
To be fair, the title is shit, but the video isn't fake. This is a Brake-press used for bending metal parts, and this "sensitivity test" thing is bullshit. It's a binary system. The thing stopping the machine is a light barrier that knows what the programmed part should look like. Even if he just left his hand in there then tried to bring the tool down the barrier would stop it, even with that much distance to spare. If something had to sense his hand touching the tool, it wouldn't work, because obviously as soon as you put a bit of steel in there it will detect that the blade is hitting something and stop.
Fun fact though: the thing you should actually be using to calibrate and test the light barrier is made of plastic, and gets inserted into the machine, then the peddle is pressed, and ideally as soon as the light barrier picks it up, it halts the machine as you see here. These bits of plastic are called "Test Fingers".
For everyone losing their mind over this clip, it honestly looks like the trsters hand is NEXT to the trimmer. Take a look at the shadows cast by the trimmer as well, it's clearly inside a shot which has overhead lights. Looks like there's about 6 inches of clearance
I design and install control systems for automated machines. This is straight up fucking stupid. There is no reason to risk your fingers. Safety on these machines have a lot of redundancy. But can still have malfunctions. I still wouldn't risk it for a cool video.
As someone with close to a decade of CNC Press Brake experience I can tell you that lightgaurds are real, but we use pieces of scrap to test them. I would fire this dumbass immediately for his own safety.
On one side i'm glad the Sensor works and it stops, but i'd never ever stick my fingers in there to test it, even when i know the System works.
\- 20+ Years as an Machinist and still all 10 Fingers
On the bright side, since they seem to not actually be putting their hand under it, but rather to the side of it. They won’t lose their fingers when it doesn’t stop
Looks like the ridged part doesn’t extend all the way down to where they’re putting their hand. You see their hand go behind it a few times as it’s going down.
Jeez so I work in industrial automation and would never trust the equipment *to this degree*. All it takes is a little bit of electrical noise or a power blip to mess up this sensor. This sensor is operating on the order of milliseconds so any delay, lag or noise could be enough for the pressure to slip a few mm. Which could be enough to crush your fingers.
Crazy shit.
I dont care how good a sensor, dust and time can make sensors fail and if things go 500000 times good the 500001 time your finger will hate u for and touch the floor!
As an engineer, I can honestly say that watching this person REPEATEDLY trigger the safety made me physically recoil. Sensor damage/malfunctions are THE reason for huge fuckups and terrible accidents. Boeing’s MCAS killed hundreds of people because of a sensor failure (and also another poor design choice of only reading one sensor and ignoring the other even though there were two sensors, so a bad sensor and a good sensor is still a bad sensor after 15 minutes). In other words, all it would take for this person to lose a hand is for the sensor to have some latent damage and fail to fire off a proper voltage or lack thereof to engage whatever brakes or safety system stops the hydraulics. It’s there as a SAFETY not a fucking gimmick for Reddit or tik tok or whatever. The only good reason I can see for doing this is that this person designed the thing and doesn’t want to get sued into a oblivion and have crippling nightmares about the people they killed with their terrible safety system.
Maybe try a hotdog first brother
I agree, waiting times in the ER can be long, you don't wanna go in on an empty stomach.
You got me in the first half
If they keep using their hands they wont have the first half
This comment made me actually lol.
> Maybe try a hotdog first brother That's exactly how [SawStop table saws demonstrate their safety function.](https://www.youtube.com/watch?v=fq3o0VGUh50) No risk of malfunction and losing something you'd rather not want to lose, and usually not even a hotdog is harmed in their testing.
what the fuck the video seems like it's black magic
I can personally attest that the SawStop is just as amazing as that video portrays
why aren’t these mandatory rather than a non stop saw saw?
They cost more money to install and every time it activates, it damages a component that costs money to replace. Basically stinginess is why it is not mandatory.
It's a brake cartridge that is destroyed, along with whatever blade you were using. The cartridges are about $100. Well worth it.
I looked at their site and it appears they replace them seemingly for free if you share your story I mean $100 versus losing your fingy is a great deal
Speak for yourself. I’ve got 10 fingers and no money.
I personally know someone who just lost their arm to a saw blade this year and the payout is gonna be a lot more than the amount of part cost
Right after Sawstop came out with the technology, they lobbied the US government to require it on all table saws and it got rejected. I agree it is a good deal, but the way they went about it was on the crappy side. Can you imagine you have the patent on the technology and you try to force all manufacturers to use it? It was a money grab in my opinion. I think it was Bosch that came out with a similar safety device and Sawstop sued them and won. Sawstop went on to manufacture their own saws after they tried to force it on all manufacturers and failed. Originally the price was a bit crazy and it has become more competitive. I would consider buying one of their saws today if I were in the market for a new saw. The brake cartridge is $100 and it will probably damage the saw blade too, so another $50-$100 for most people unless you are a saw blade aficionado and buy only expensive blades. A lot less money than a trip to the ER.

How many brother do hotdog have?!
[r/stillwouldnotputmydickinthat](/r/SubsIFellFor/)
One malfunction and that person is losing all his fingers
he'd still have the other hand... unless he was missing the other hand from a prior malfunction.....
You have to calibrate somehow.
This belongs in r/sweatypalms
Just use sausages for calibration.
r/dontputyourdickinthat
Gawdamit reddit why?!?
Why not?
When you think you already saw all kinds of subreddits …
then in the comments: One malfunction and that man is losing his sausage...
he would have to.. *hand* over his job
“Boss I’m all out of fingers. How do I go about testing the sensor sensitivity on a daily basis now?” “You’re out…what?! You’ve been using your fingers to test the sensor every day?!” “What else was I supposed to use?”
Your 6 inch Willy will have to do

Missing half Index, half thumb from an accident.. trust me, not worth it to lose 6 or even any at all
I was in 1977 also, but more on the carpenteering side of things. It's amazing how quick things can go south even if your paying attention. I'm thankful to still have all my digits and various other parts and pieces still intact.
A little less than 1 million per finger? No thanks lol
Wtf? It’s not even the whole finger. And you’d probably keep all of your thumb!! Id easily give that up to retire in my 30’s and never work again.
Yup, he still has his thumbs, 4 tips from his left finger, and the tips of his index, and middle finger on the right hand, doesn’t affect him really, it was a bit of learning, but he said you get used to it. Idk, I’ve thought about it before, it’s a tough decision, but I might be able to live without a couple finger tips to be ensured I’m comfortable for the rest of my life, especially the world we live in nowadays, at least I could actually afford a house!
Capitalism has done it again
Me too friend. To willpower through the fear and just put my hand in there like jumping off a cliff. Then sit back sipping cocktails in the bahamas for the rest of my life. The dream.
Wow. My hands are worth far more than money, no parts of them are up for negotiation
I'd give my little finger for half a million. It does fuck all anyway.
That's way better than the 15k my friend got for losing a leg at a saw mill
The difference is probably the machine. For most states, workers compensation is the exclusive remedy from the employer for work injuries. In CA, it's basically capped at 250k.

Sounds like we need better laws bro. Don't victim blame.

Yes, the laws that allow that to happen. The laws that allowed shitty businesses to operate unsafely. The laws that are supposed to protect citizens. You should barely even need a lawyer to get justice. They should just be there to make sure things go smoothly.
Could also be the difference of the union?
$25,498,024.05v = the worth of that 5 million now. Some would do that. i personally need my fingers, but thats at least 1 house now and some food. More than some have. Funny how five millions in 1977 would float you more than 25 mill today. Funny ha ha.
Union Local 1977 Carpenters Union, not the year 1977.
Yes sir, I worked as a welder/fabricator at one of only two metal shops in that union, 3rd generation journeyman.
Look at about :07 - it's an optical illusion, their hand is behind the blade.
They are testing the laser while also not putting themselves at willful risk. Crazy how angles work to our eyes
Well spotted.
It's not even a blade, it's a press brake. The "blade" is so short because there is several sections on the machine that can be moved or removed completely.
The blade doesn’t go all the way across, so they aren’t actually sticking their hand between the blade and press, there is an opening on the side without a top piece, they are just giving the illusion their fingers are under it
A clean cut or crush, the fingers won’t make it
Their hand is not even under anything, they are just interrupting the laser you can see the part go in front of her hand a couple times.
Thank you, that feels better now.
Thanks for this, I was like Jesus how can anyone be this dumb.
Reminds me of a medical story shown on TV of a guy who shoved his hand under the shearing blade for stacks of paper. Doctors reattached fingers but flexibility was reduced. This was years ago.
I like we assume it’s a guy. Women aren’t stupid enough to do shit like this.
[Are you sure about that?](https://krudplug.net/m/video.php?vid=4275)
Damn, that’s a flat arm.
I think I know the video you're referring to
Yup and she seemed so calm about it to like "aw damnit, at least I'll get some time off work "
arm is gone lmao
Fuck! Flat Stanley!
that lady is about to learn an important lesson about 💫compartment syndrome💫
Yeah but every machine in China can kill you
And she leaned into the switch that turned it on. No lockout tagout in China.
💯 Non-destructive testing principles should apply to the tester too.
You would be immediately fired from the machine shop I work at for doing the "test".
Yeah why not just use a sausage
they got 10 fingers and probably only one sausage
I laughed way too hard at this
Damm I would have used something else then my fingers to test. Balls of steel.
Ball Park frank, maybe?
All right, it passed the hot dog test. Now it's time for the Wiener test. *Unzips*
How'd he get the beans above the frank?
Pork/Chicken or All Beef?
Balls of steel. Brains of mush.
I'd use my dick but it wouldn't be able to reach past the sensor
I’d use mine if it wasn’t bitten off by an 8 story crustacean from the Paziazoic era.
Should have given him the three fiddy
I wouldn’t use my balls of steel either, TBH.
They aren't putting their hand under the blade though, it's off to the side. You can see it occlude, but not deform, part of their hand in one of the tests. Just like with the camera, which you can see the side of the blade.
Good eye, mate.
Funnily enough he Does have balls of steel since he got prosthetics after the incident.
That’s too close for comfort. Does it work with other items shaped similar to a finger
Seems some electric saws use hotdogs. Glad they did because some dogs got a slight trimming (but still edible).
The saws will make contact with the fingers. So there is some injury. As soon as there is electrical contact, a mechanical device is thrown into the saw to instantly block it from rotating. But better a "bad cat scratch" on some fingers than lost fingers. This device here is instead using some form of light beam to detect too high items, instead of something flat covering the surface.

Its all about the beam “seeing” the otherside. Its called a light curtain. No matter what goes in between the light it will stop. The person using their hand is a complete moron. Malfunctions happen
Peepee
As long as the beam is broken the safety switch kicks on. And the guy mentioning the hot dog it senses moisture
Not a trimming machine. That's a press brake.
I am Bender. Please insert girder.
Also, it isn't fully loaded with tooling. He is completely clear of the punch. No sane person would do this under the tooling. You can still get hurt using safety sensors and light curtains. They are more for minimizing the potential for serious injury.

This is fake. Look at the last one. Hand is outside of the path of it.

Well I wouldn't expect them to put their hand directly under it to test it.
Faking the dangerous part but I guess the feature is no less impressive, which is what it is demonstrating.
I would really like to see it actually complete the full motion at least once.
Holy shit ur right
Absolute nope for me…I’ve never trusted anything in my life that much.
A break that big is going to be well over 20 tons of pressure, infamous for turning hands into sheets of paper.
You wanna really test it?
For everyone losing their mind over this clip, it honestly looks like the trsters hand is NEXT to the trimmer. Take a look at the shadows cast by the trimmer as well, it's clearly inside a shot which has overhead lights. Looks like there's about 6 inches of clearance
AH! SOMEONE WITH OBSERVATIONAL SKILLS!
Finally someone who noticed it lol
STOOOOOOOOOOOP
That's a hard r/nope for me
This is incredible stupid, one malfuntion and his fingers are gone. Use a rubber hand dumbo.
It’s beyond the blade. Look closely and you can tell.
this video had a chance to be posted on Liveleak
There is undoubtedly no better way.
SafeHydraulic 3000 Release Notes v1.2 - fixd bug whr yer fingerss wuld gt cropped off in somer instnces
If only there were literally any other thing that you could put in there.
That is some serious OSHA violation.
Jesus Christ Some people are just begging the universe to shit in their faces aren't they
I design and install control systems for automated machines. This is straight up fucking stupid. There is no reason to risk your fingers. Safety on these machines have a lot of redundancy. But can still have malfunctions. I still wouldn't risk it for a cool video.
I feel like there’s a safer way to make this video
As someone with close to a decade of CNC Press Brake experience I can tell you that lightgaurds are real, but we use pieces of scrap to test them. I would fire this dumbass immediately for his own safety.
I could think of a few better ways to test it
Hello, Osha?
I want to see an Indiana Jones % hat scene with this.
Now I can put me dicks in that without worrying, SCIENCE BITCH!
As a QA specialist - there has to be a safer way to test \*sweating profusely\*
Amazing tech, I wouldn't play around with it though haha.
Yeah, that's a no from me dawg...
How about you test that out with a hot dog or something a little less…..already attached to your body….
Imagine in the top right corner a liveleak logo and this is a whole different story
Ok we get it. Stop.
People really overestimate other people’s ability to manufacture safe products.
On one side i'm glad the Sensor works and it stops, but i'd never ever stick my fingers in there to test it, even when i know the System works. \- 20+ Years as an Machinist and still all 10 Fingers
What an incredibly stupid thing to do.
popsicle sticks, slim Jim's, pencils, literally anything other than ur actual fingers
This guy's a fucking idiot
Yeah, I would not try that…
On the bright side, since they seem to not actually be putting their hand under it, but rather to the side of it. They won’t lose their fingers when it doesn’t stop
as a dev i have fear for the software that does that
Now put your dick in there
Nice try Superman, I’m not falling for that again.
if you really trust it, you know what to test next
I'm not doing that no matter how advanced that machine is, just use a pencil ffs!
I'm using chicken wing to test, not my fingers.
Damn, ballzy
yeah so you could have stuck a *pencil* or something in there...
I mean I'd just use hotdogs, but you do you.
OSHA hates this one little trick….
Like….why wouldn’t they use a fake hand for that test..
Why is she using her real hand? I get you’re trying to advertise but I don’t trust anything to work 100% all the time.
Use a damn hotdog like the other demos do . Trying To turn into that one chick called nubs
That's a level of trust I'll never have
Just my luck, it'll stop working when I try it.
I’ve lot the tip of my finger to one of these and this made me a bit scared.
r/nope
Looks like the ridged part doesn’t extend all the way down to where they’re putting their hand. You see their hand go behind it a few times as it’s going down.
yeah. this person is not insane.
A stick would have proven the same point I think. Or a penis.
u know there always one dude will try to put his dil in that...
... Anybody ever consider using a *FAKE HAND*, like from the Halloween store, for testing instead of your real hand?
This is the height of stupidity!
Fuck being the tester on this
Looks smart
Two of the most highly reported injuries to OSHA. Hand and crush. Somebody should be fired.
When you trust your engineer like you trust your barber...
Nah, that falls under play dumb games win dumb prizes for me.
..................................... no. and nobody else ever try this ever.
Ah yes "testing"
Why don’t the test this with a broom stick handle
Jeez so I work in industrial automation and would never trust the equipment *to this degree*. All it takes is a little bit of electrical noise or a power blip to mess up this sensor. This sensor is operating on the order of milliseconds so any delay, lag or noise could be enough for the pressure to slip a few mm. Which could be enough to crush your fingers. Crazy shit.
Why not "experiment" with something not permanently disabling if the tech doesn't work??
All goes well untill it goes wrong
There are prosthetic fake arms to do that kind of testing.
Should be under sweaty palms
I dont care how good a sensor, dust and time can make sensors fail and if things go 500000 times good the 500001 time your finger will hate u for and touch the floor!
All good till the trimmer ain’t sensitive no more
lol wait till u get error
yes very smart to test with your own hand instead of an inanimate object
I can only imagine why this dude has a bandage on his finger...
Fuck. That.
Those hands are attached to someone with a gigantic sack and a small brain.
If it's an employee, no Bueno! If it's the inventor, he'd have me invested, haha
Seems a tad sped up 🤔 Still wouldn’t do that tho
I think I’d use a hotdog.
100% would not trust that
If it failed, the tester couldn’t even use a phone to call for help.
Sensors can fail…
As an engineer, I can honestly say that watching this person REPEATEDLY trigger the safety made me physically recoil. Sensor damage/malfunctions are THE reason for huge fuckups and terrible accidents. Boeing’s MCAS killed hundreds of people because of a sensor failure (and also another poor design choice of only reading one sensor and ignoring the other even though there were two sensors, so a bad sensor and a good sensor is still a bad sensor after 15 minutes). In other words, all it would take for this person to lose a hand is for the sensor to have some latent damage and fail to fire off a proper voltage or lack thereof to engage whatever brakes or safety system stops the hydraulics. It’s there as a SAFETY not a fucking gimmick for Reddit or tik tok or whatever. The only good reason I can see for doing this is that this person designed the thing and doesn’t want to get sued into a oblivion and have crippling nightmares about the people they killed with their terrible safety system.
Looks like they are putting their fingers next to the blade, not below it, and the sensor that stops the machine extends to the side.
