I also thought about the finger-breaking possibility, too. Kind of like
air bags, which can break glasses, thumbs, or even arms if they get in
I also wonder about cuts in heavy wood. I don't know about you, but
sometimes I cut large, heavy planks, but not too thick. So if you are
cutting a heavy wide board, weighing 10 or 15 lbs., can this thing push
it up fast enough to urge your fingers out of the way?
As far as the SawStop controversy, jeez, will everyone just get over it?
In mass production it will add a small amount to the prices of saws,
can be disabled if not desired, and if automatically mounted on all saws
will protect the idiots who value a few dollars over their fingers.
Just like seat belts and air bags in cars. They come with the cars, but
can be disabled. If some guys really, really, really want saws without
SawStops, there are uncountable used saws on the market in great condition.
