Got a tenon/chuck question..

>I have been wondering...what do you folks use on a finished tenon (when doing natural edge bowls, I completely finish the tenon)to wrap it to keep the chuck jaws from damaging the "foot"?
I think I saw where Russ uses tape, but I'm wondering if a heavy duty rubber band might work? What else do y'all use??

>I turn the tenon away, or re-shape it between centers as a final step. Some smooth jaws allow you to gently grip a finished foot if it is sized and shaped exactlt right -- however, that limits your creativity to the sizes of chuck jaws you have, and I rarely do it.

I turn the tenon down to the foot that I really want. before I had a vacuum chuck I would put leather or some other soft but fairly high friction stuff on an scrap of wood on my faceplate. This would go inside the bowl and drive it.
Then you bring up your tailstock and hold the bowl on this homemade drive center. then you can carefully turn away the existing foot and make a new one.
When you turn the original foot with a chuck you might not have a center point. I made a little tool that fits in the back of the chuck. It has a small metal rod with a point. I push it in and it marks the center of the bottom.
If you havent' done that simply push the tailstock up gently and rotate the bowl by hand. Adjust the tool rest until it is close to the foot. Now you find the high spot and adjust tahe bowl a little. Soon you'll have it running true and can start to turn.
