wow i was scared for him..

[moomooCow]

I didn't see the video, but I thanked you for your avatar.

[jdmhaze]

I know a few carpenters who coulda used one of these.

Even if you know its going to stop, it takes BALLS purposely running your finger into a blade like that.

[Greenstoner]

impressive

[vitaminG]

coolest thing ive seen in a while

[sobee]

just putting your finger there takes MAD balls

[MG1]

I dare anyone to stick their dick in one of those.

Yeah it's been out for a t least 5 years. A lot of shop teachers have them now. Kids do some really dumb things in tech ed and this will at least "cut" down on bloody incidents and lawsuits.

I remember being on the PAC at my son's school. We gave the OK for one.


Strangely, this technology was not around when one of the tech ed teachers cut off a few of his own digits. Nevermind the kids.

[LiquidTurbo]

^i LOL'd

[chun]

Freaking cool but I hope people don't start getting careless (even a little bit) with saws just because the technology is available.

[CHOWMEINZ]

whoa, that is insane

[xilley]

now what if it hits the nail? does it stop too

[Vansterdam]

timewarp FTW

[Razor Ramon HG]

I was expecting to see a little bit of blood, but damn..

[Euro7r]

Shiet, this is crazy. Lots of balls to attempt something like that.

[MG1]

Could turn out to be like that samurai sword mishap on the shopping channel one day. Never be too cocky when doing demos.

Here's a little bit of blood.......... from their site.

If some kid does trip the saw stop the replacement of the mechanism is quite expensive. Still worth saving a finger, for sure.

BTW, this is a repost from way, way back......... so it doesn't count.

[gdoh]

^ahaha the comment "screw the sword i want the table"


dam, i held my breath lol. thats crazy

[Ferra]

does it mangle the machine entirely or just the blade?

It'd be pretty useless if the stop screw up the machine or the motors, coz I can see a lot of false positive happening...i.e. dripping sweat, metallic/nails debris trap in wood...etc

The should've designed it such that the sawblade drop down and pull back when triggered (instead of forcing the motor to stop from 2000rpm to 0 in a few milliseconds)

that way there is no expensive replacement every time a false positive happens

[Tegra_Devil]

they just have to replace the brake system and blade...everything else is fine...they said in the video its around 60$ for a new brake and blade

[Gridlock]

Cheap blade then, because a quality one runs about that alone.

[MG1]

Brake itself is 60 - 70 bucks to replace. Blade is on top of that. Again, way cheaper than a law suit or poor shop teacher..... errrrr.......I mean student getting fingers cut off.

[Presto]

It's 5000rpm to 0rpm in 1/1000th of a second. I doubt gravity can pull the blade down fast enough.

[Gumby]

Wow that's amazing...

[dmm]

These ladders are very safe ...

Harold, from the first clip, is not OK. Ever since that episode aired, he has not been on television, as he lost his confidence and turned to drugs and alcohol. Now a homeless person, Harold is hoping to be rediscovered like the dude with the golden radio voice.

[GabAlmighty]

Something pre-tensioned that gets released?

[Ferra]

obviously i am not talking about using gravity to pull it down...

[RRxtar]

^ the way it works now, the thing only has to move a milimeter before the blade catches it. if the blade had do drop down and back it would have to move several inches. i dont think theres anything out there that can move something a few inches in 1/1000th of second. and be affordable and reliable. not to mention the force it would require..

[Alcoholics_Anon]

Wow this technology would've saved my friend's finger many moons ago. I remember the horror, blood everywhere. Had to help clean up the mess too.

[Guy_LikeWhoa]

so what happens if your hands are dry?

actually...i think as long as the blade pulls back & down faster than your finger is moving forward...that would be fine.

They could have used that at my school when I was in high school. There was one guy who chopped off a full digit in grade 11. You would think he'd learn but in grade 12 he put his hand into the blade once again.

Maybe the school shouldn't let the "slow kids" in the wood shop :fullofwin:

[Noizz]

You are still conductive whether or not your hands are wet. If dry hands can operate your iphone, it will operate sawstop.

He was Russian, strong like bull.

[Gridlock]

Now, if they license the technology to someone like Dewalt, it will become the standard in table saws and band saws.

Or they may think they'd like to build their own brand of safe saws, and it will go nowhere.

In Solviet Russia, sawblade cut YOU!.... wait.... damnit
