Allen, great post. Let me add two related safety posts--
I always wear steel toes whenever working on a Stovebolt engines on my engine stand. You can research some of HRL's posts as to why.
I have set my T-shirts on fire a few times when using my angle grinder and holding the work material in my vice. The sparks hit at just about my belly button. Easy to snuff out, but kinda scary when you feel your tummy getting warm and start to smell burning hair, then look down and have an OMG moment! Now I usually wear a shop apron, but I can't say that I don't sometimes get lazy about it. Just a couple weeks ago, my being lazy caught one of my favorite Nascar shop T-shirts on fire. The shirts don't look very good when they have about a 6" burn hole at the belly button!
