Finger touching SawStop video

This is the first time I had seen this, it may be old news.

I've always wanted to see this done this way. I just hope some wackos don't take it too far. The $60 cost of getting the "repair" done should help a bit but it seems there is less and less "common sense" in the gene pool. The stat of 10 fingers per day is sobering.

I wouldn't attempt that, EVER!! What if you happen to have the one in a million that had a defective part in it and the SawStop didn't work? NASA tests their Space Shuttle a thousand times before launch and they still have problems.

I do own a SawStop now, but never had an accident with my old saw in all the years I used it. I don't plan to be any less careful even tho I now have the SawStop.

It's been around for a year or so, but it NEVER gets old!

And the $100+ forrest (or similar quality) blade.

I was more interested in the physics behind stopping the blade. I loved the slow-mo of when the cartridge fires. It's gotta be a pretty beefy saw to take that hit I would think.

yep quite old. a search here shows the first "Sawstop" video discussion post dated 4/3/2003. And four pages of additional posts since then.

Crockett, the secret is not so much a beefy saw (actually its quite a beefy saw for the main purpose of sawing) but of energy dissipation and there's a $60 (I didn't verify this number) sacrificial brake and cartridge designed to take all the energy and deform the brake to stop it quickly.

and, as someone mentioned, it'll eat your $100 blade as well.

Still cheap considering the alternative is your fingers but stoppng the blade quickly involves fast dissipation of a significant amount of energy and that costs money.
