If you think that's bad, you should try holding a milling cutter in a three jaw. Sometimes you do what you have to do to make the cut.
Make it fit.
in a post from 2007 i see you used a diamond burr in the drill chuck. now im really surprised. you didnt dress it, did you? how come it worked? that chuck must be a real treasure.
