[sanddrag]

The reasoning for no gloves while using power tools (or anything that spins really) is simple. Gloves are stronger than human skin. If your finger hits a grinding wheel for example, the worst that will probably happen is you lose a little chunk of skin. If you are wearing a glove and hit the grinding wheel, you could break and or/lose fingers quite easily. I did an experiment once on a large disc sander (16" or so). There was approximately 3/8" gap between the wheel and the table. The sander had been turned off for about 3 minutes. It was still spinning down. It had good bearings and a large flywheel effect. Anyhow, I took a shoe, and stuck it right up against the wheel (bare steel wheel, not even any sanding disc). It sucked the whole shoe about half way in, into this 3/8" wide gap faster than I could blink. I mean, think about how thick a shoe is. And there wasn't even a motor powering this thing at the time. This machine is capable of taking a whole hand without a doubt. And this machine is not too different than something many teams probably use. So, don't wear gloves while grinding (yes, it gets hot, yes, that's what water is for), sanding, drilling, working on sprockets and chains or gears, etc.
