I've got an Apprentice Collet Chuck from Craft Supplies and I put in a piece but when I tightened up the ring I found the piece was too small in diameter and it wouldn't sieze but when I took it off the collet is stuck in the ring. I'm not familiar with using this tool, this was the first time, but I'm puzzled at what happened. What could I have done? I tightened the ring, not overly so, when it didn't hold the piece I didn't force it. Could anyone give me a hint on what I may have done and now what do I do? Appreciate any input. Thanks, Bob
