Just to be clear, I was referring to buffing wheels. A buffer ether spins at about 1750 RPM or 3500 RPM both of which is fast enough to hurl a knife or pointy object into you! More people have been injured by the buffer than any other piece of equipment in the shop.
Stay focused, no talking to anyone, listening to music etc.. 100 percent of our 10% brain power on what you are doing. When looking at the wheel from the side there are four quadrants. I always stay in that number 3 and wear a full thick apron that hangs past my knees and boots to protect the family jewels and arteries in my legs from flying pointy objects.
If you cut one of those arteries in your legs, and are alone in your shop its possible to drain out very quickly!:what!:
Lots of makers don't even have one in their shop for these reasons.
