Back in the shop after a long time absent and relearning wood turning. Turned a piece round and turned a tenon. Put the tenon in the chuck. Hogged out the center and was going to use the Cole Jaws to finish the bottom. OK. Got it set up and the piece and CJs were wobbling out of round. Didn't even try to turn the piece! Never had a problem with the chuck and original jaws. Disappointed with the jaws. Checked and the jaws are not numbered like the small jaws that came with the chuck. I like the chuck even though I'm limited to the maximum opening of the original jaws. Now I'll need to make a jam chuck with the live center and a point to turn the bottom. Suggestions are most welcome. Thanks.
