The guy with the hot dogs probably saved his company millions of
dollars every year, just by putting a little scare into guys who
had gotten too complacent.

I've had a couple of close calls in the shop, like getting a fingernail
broken or an "acid brush" wrapped around an end mill and then thrown
across the room. I now use old toothbrushes for chip clearing and
applying cutting lube. They behave a LOT better than those metal-handle
acid brushes.

But, the worst injuries I've had were with unpowered tools. I dropped
a 30 Lb scraping straightedge on my big toe, and limped around for
months. And, I wrenched my back working a 24 x 36" surface plate out
of the back of my car. That one may never heal, and every time I
overload the bad disc, it flares up again. Damn!
