SawStop Braking Mechanism

[Jester129]

I can remember getting my first (and only) table saw. No training, a quick read of the manual and how to set it up! That was it! Surely new saws somehow need, even if it's a video to watch regarding safe use, some kind of instruction? I'm too aware that I was very niaive, even if very wary, when I started using a table saw.

A tempting belief, that one. Many humans, me included, indulge in the schadenfreude from time to time. It's difficult not to somehow enjoy seeing a dafty bitten by the consequences of a serious episode of daftness. However .....

Even nature gets things wrong and so to weed out the sub standard it came up with survival of the fittest which was supposed to remove anything that failed to meet the standard.

Just a couple of quick calculations tells you why demonstrators don't use their own fingers: well I certainly wouldn't.
If you assume the following, and you may want to argue details but the basis is still the same - OUCH!!
Saw RPM 3000rpm, 40 teeth, Diameter 254mm, stop time 1 msec (1/1000 sec). then the number of teeth passing through your finger in the stop time = 2.
TWO teeth through your digit. That's going to be a massive bruise even if you're not cut. And this assumes a stop time as aired above although it was also said that the detection time may increase that significantly. If it doubles to 2 msec that's FOUR teeth.
I, for one, am keeping my wiener well and truly hidden.

Third obvious reason is that it's a machine and like all machines it will fail at some point.

I would have left the braking cartridge stuck in the blade, added a simple quartz mechanism, a pair of hands, for a nifty workshop clock.
