well if this get going you wont anymore....

YouTube - Time Warp SawStop Table Saw on Discovery Channel

 

pretty cool

 

That is awesome - I know a handful of people that have made costly boo-boos with table saws!

 

a great place for these would be high school wood shop classes.....but the kid has to pay some part of the replacement cost so that kids just dont do it for fun....

 

Yeah that would be a great place for those! I ran a scroll-saw through the web between my middle and index finger almost to my knuckle - maybe they're develop something like this for all the sharp stuff!

I didn't catch it in the movie, but who made the saw?

 

its made by SawStop, and they have table saw, jig saw, chop saw.....but only selling the table saw as of now...

 

My Geometry teacher's husband just about completely lost one of his thumbs to a tablesaw.

I've seen that system before and I think it's a good idea. I hadn't seen the guy demonstrate using his own finger before, but I trust it a lot more now that I've seen the guy do it himself instead of just saying it does what it's supposed to.

 

Awwww, stuff like that is for sissies!




Just kidding. But, as a shop teacher, I am more worried about kickback than digit separation. The kids usually have at least one "good" kickback each year.
It doesn't matter how many times I tell them and show them how they have to maintain control of the board and follow through with the cut; someone lets it come off the fence a little bit and BANG!, there goes a chunk of wood flying through the air. This invariabley happens when they refuse to take the time to replace the guard and splitter that is used for all through-cuts after the saw had been used for dadoes or rabbets.
It even happened to me last year (first time in 25+ years) making a rabbet cut in a piece of 2 x 4 with a dado blade. But it was due to a hidden knot in the board, not because I let it come away from the fence.

I have seen chunks of wood fly across the room. In one of the other shops, a kid had a kick back and it broke the teachers forearm from 12 feet away while he was walking behind the saw to another area of his shop.
I have seen kickbacks punch a hole in 5/8" T1-11 shed wall 5' behind the saw as well as in an aluminum garage door over 20 feet away.
Fortunately, the kids do listen as far as how to stand with their bodies out of the path of the wood, should a kickback occur.
It is very difficult in a class of 20 to watch each and every student as they are working at the table saw and help other students at the same time, but I try hard to keep an eye on them. I have been able to stop numerous attempted crosscuts with the fence (as opposed to with the miter guage) in time to prevent the forthcoming and inevitable kickback. But I have missed some that just got careless and let the board come away from the fence enough for the blade to grab it and throw it.
I just finished and submitted my budget for next year about a month ago. I have debated internally whether or not to get these and I am going to amend it to buy a couple of those devices. One for regular use and one as a spare in the event the first one is actually discharged. The possible downside I see is the potential for reliance on the safety device instead of proper technique, leading to kickbacks and the possible resultant injuries.
But, they certainly are very cool and effective devices.

A friend of mine was laid up for over 2 years after cutting deep into the palm of his hand. 2 years because they robbed tendons out of his ankles one at a time to repair the ones that were cut in his hand. He also had screws in his forearm with "fishing line" strung to his fingertips to keep his fingers extended so the new tendon repairs would stay stretched until fully healed.

It is a very dangerous tool.

 

ckal, if you get them, perhaps just don't tell the kids that you have them? Would prevent them setting them off for the hell of it, and would keep them from accidently getting stupid cause they rely on it?

 

Many school systems have stoped wood working because of injuries. I worked in a machine shop and the boss came back to the shop and started to talk to a worker and in a casual manner started to prop his arm against a table saw table and ZAP! off went his finger. He didnt hear it running . I have used some very dangerious machines (some with a history of cutting off entire hands) and still have all 10 fingers. Luck maybe but I say luck isnt an accident Ive always been careful.

 

ckal704 as a shop teacher, did you ever have a student lock something up in a drill press? I'm in college now, but I remember one day in shop class in middle school when a kid was drilling through a 5' piece of 1x3 steel rectangle stock way too fast with a hole-saw and he locked it up and thing swung around and broke two of his ribs!

 

A kid working construction in the are I grew up in got his whole foreare ripped off by a table saw. Apparantly it was missing some guards and he somehow slipped and fell into it. Luckily though after about 6 months the had regained full uses of his arm.

 

It's a good idea, it's been around awhile. Notice lack of guard. I know a guy who cut off 4 fingers on his table saw. They were able to re-attach. He said a bunch of brown bottles might have had something to do with the incident....

 

I know someone that took a wild ride down someone's driveway on a wheeled scaffold for the same mistake lol...

 

funny this thread was started today, we sent one of our guys to the ER today, the saw just nipped him, but he got a coupla stitches.

we've been thinking about the sawstops for a couple years now. we have 4 powermatics that get used for 8 hrs a day, 5 days a week
