Here is our solution to chop saw safety.
Big piston is about 140 pounds of force, small piston is about 40 pounds. Clamp is actuated by a foot switch toggle. Anything bigger than 4" in a dimension gets cut with the band saw.
We also added a pneumatic brake to the blade, if the blade is off the solenoid fires and it pushes the side of the blade and stops it in about 2 seconds. You must depress BOTH buttons on the 2 handed handle to turn it on, both hands must be used.
The main thing I have noticed that causes parts to get ejected are small loose pieces getting snagged by the blade if it is brought up too soon. That is why we clamp both sides.
This thing has been amazing this year, 3 HP 3 phase motor. No injuries from the saw. And it only cost $95! plus some parts, but still way cheap. I love auctions.
