18-Nov-2014 First spinning operation completed, ready to be removed and excess trimmed. You can see some of the buckling problem I am having when folding the metal over. I think it could be solved by using a hand-held backing stick behind the metal while using the metal tool on the front to compress the metal, but my mandrel is so close to the chuck jaws that I can't do this. I remove the piece from the mandrel and trim the excess away. When spinning I move the carriage over in steps closer to the chuck as the spinning progresses.
