Yep some of us have learned the hard way, I did not mention in my first reply that I was only 15 years old at the time and was using college machinery and was doing what I was told under instruction, I was taken by the teacher to a local hospital for stitches to my forehead. When I was released I found the teacher had gone and I had to walk two miles home in bandages, my father said that will teach you to be more careful, imagine the parental reaction to those events these days. Next time I went to the metalwork shop the buffing wheels had miraculously grown wheel guards.
One final point about buffing thin parts is that platers have do it all the time on car trims etc, their just not 15 years old and are experienced at what they do.
