We had training for new employees on the table saw. Some listened and some did not.
They replaced our saws with Saw Stops and there were several times that they did save at least a finger tip. The only thing you could see on the finger was a slite grove in the skin and usually did not bleed.
We did have one person try to flick a small piece of off fall from just in front of the blade and he did have damage to the finger, more than normal. Flicking the finger in front of the blade was faster than a normal feed rate so consequently there was more damage.
We cut aluminum sheet goods on the saw all the time and you had to lock out the safety device before using the saw or it would set off the safety cartridge and cram the blade into the blade stop. It is not recommended to use the blade after it has been stop by the mechanism. About ounce a week some one from another shop would set off the safty, most of the time they tried to sneak away like nothing had happened.
About ounce a month people in our shop would set it off. If you use it to cut aluminum it should be blown out with an air hose before it is used again or it could set it off.
I did like the Saw Stop saws, they were nice saws.
If you have seen the demo where the inventor puts his finger into the spinning blade you will notice he is moving that finger slowly!
