Good advice! (Actually we talked about a shop safety forum and I dropped the ball on setting it up) That's where this will end up...
"Tired" and "Spinning Blades" do not mix. I fear saws already because I know too many 3 fingered guys....
Someone made a device that would stop a blade instantly when it touched flesh - they demo'd it with a hot dog. There was a tiny scratch on the hot dog, nothing else. I need to see if I can find that article...
