Another high-school story-one of the old machines in our shop was a big ol' hydraulic planer, the bed was about 10 ft. long. One kid had a big workpiece mounted up, I think it was a big vise that we had welded the jaw up, & he was planing it back into shape...other kid was guiding him in w/the tool, as he moved across to start the cut. after a couple small moves, he said, "Come on, you've got a long way to go!" so the guy gives the crank a couple turns, & next stroke the tool took about a 1/4" cut, which didn't phase that big cylinder at all...a big ol' full-curl, smoking, dark blue ram's horn flew off the tool & stuck right in the middle of the second kid's chest-stuck in his nice white T-shirt...He screamed like a girl & pawed at it like it was a tarantula. Everybody had a laugh, but it could have been serious, of course. I still remember the sound of that old machine, it had about a 10 horse motor on the pump. It's probably a Toyota block by now, or mixed with tin cans & turned into a Harbor Freight machine tool... :'(
