reminds me of an apprenticeship story we had a material at work called monel. made a nice ring so one apprentice was making a ring out of a monel bolt. bored the ring shaped the od and polished it to a bright finish. then parted it off . ring fell into chip pan. he picked it up put it on his finger. still very hot and a good burr on the inside. by the time he got it off his finger was bloody and a permanent burned ring was on his finger. called him Burnie after that. he didn't laugh go figure. bill
