This guy purposely caused kickback on his table saw to prove a point.

Make sure you watch what happens at 4:20 into the video.

He agrees with anyone who calls him an idiot.

Excellent vid, valuable lesson.
He's not an idiot, he just didn't have the control over the situation as
he expected. ***** happens, even with good intentions.

He proly would not have lost a digit or part thereof (as in a RAS), but he
certainly came close to requiring a lot of stitches, and poss. nerve
damage -- which can be almost as bad as losing a digit.

How does a riving knife work? *Never saw one before this.

Apropos of this, the SawStop:

He claims sumpn like 3600 accidents a year, all severed digits? *I doubt it.
Table saws, iiuc, don't nec'ly sever digits -- RAS's do. *So I'm sure plenty
of people get deep cuts on table saws, but not nec'ly severings.
He may have also been lumping RAS accidents with table saw accidents --
assholes aren't nec'ly careful with stats.

But, this demo was ess'ly bogus. *If the saw stop didn't work, he would have
gotten a bit of a nick (MAYBE), before his nervous system kicked in -- ESP
the way his finger was glued to the table..... *sheeit, I'da done that
WITHOUT a saw stop.... gimme a fukn break with that bull****.....

Now, let him put his system on a RAS, and test DAT with his finger, cutting
in climb.... *yeah, I'll hold effing breath....

Finally, the fuknCOST of this system.... *holy ****.... * God help the home
woodworker if this thing ever becomes mandatory. *Which could happen, given
that they now make crawling helmets for toddlers:

Even insufferable Manhattan Yupsters have a tough time swallowing this one.
Trader4 and Terrel would proly buy a crawling helmet, tho....

I'd love to see the system! *I wonder if it could be adapted to shapers,
routers and other cutting machines. *It would help a lot with OSHA
problems where guards make production next to impossible.- Hide quoted text -

No reason it can't be adapted to those things. It's basicly
a touch sensor that reacts to increased capacitance
from a person coming in contact with it. That triggers
a spring loaded ram that jambs into whatever is spinning.

And you've hit on the beauty of the system. UInlike many of
the safety features on products today, this one is not
intrusive. I just bought a Poulan electric chainsaw. And while
I'm happy with and think it's a great buy for the money, it
does have two safety features that are a pain. One is the
button that you have to push before you can pull the trigger.
With gloves on, it's hard to do it. The other is it has a hair
trigger that you have to not only keep fully depressed but
a LOT of pressure on to keep the saw going. If you just
let off the pressure a bit, the saw begins to stop.
