Since we are on the subject of Nova Chucks...
My darling bride bought me a Super Nova Companion Chuck for Christmas amongst many other goodies.
This new chuck performs poorly in expansion mode - I make pleny of boxes and have the need to use the expansion mode twice for each box - in the manner that I make them - and usually have one of the pieces fly off while in expansion mode.
It seems that the jaws contract on their own while the chuck is spinning. I usually expand the jaws enough to fit snugly, but not crack the work piece, so the thing starts with a firm grip on the piece. Then usually within 1 minute of the start of the machine, the jaws begin making a clicking sound - that is my signal to stop, expand and restart. Sort of like lather rinse repeat! There is no end to this cycle of start stop tighten start. This has tried my patience and made my feet ache!
Any suggestions?
