All workshop machinery can be dangerous. When I was an apprentice in the 60's I had to work in every department and was in the Coppersmith's shop at the time. The old guy teaching me was cleaning up a large soldering iron on a bench grinder fitted with a wire brush wheel. He must have done it thousands of times, this particular day, for some reason the grinder dragged the iron and his hand in. It ripped his thumb and forefinger off his hand, Not pretty - I was stood next to him at the time. Now you would think that would make me extra careful. It does, but I've still managed to get a sleeve caught in a lathe chuck, when somebody spoke to me as I was working and I turned around. I was lucky, the shirt ripped easily and I only got a two inch gash in my forearm. Believe me - It's extremely painful, you have the huge bruise from the impact of the chuck jaws as well as the cuts! (And it continues to hurt just as bad for days). Steve Blackmore -- ------------------------------------------------------------------------------ Come build with us!
