Tullies' "Stupid, stupid, stupid" thread was very enlightening. The basic lesson was "don't use a fence when cross-cutting on a table-saw". Of course the danger is obvious when one stops and thinks about the mechanics of what is happening. But as a newbie, I've done this many times, simply because "I didn't know what I didn't know."

So I was wondering if the old hands on SMC could offer other basic guidelines for workshop safety. I'm thinking particularly of practices that are not immediately obvious, but would be unpleasant to learn the hard way.

Thanks!
