Hi George

Tailstock brought up with a soft pussy foot to keep the bowl in place
and ugly or no recess would make for NO problem, resurfacing inside and
also outside heel marks, and a vacuum chuck if used with a proper sized
vacuum drum chuck also would fit the bill.

Have fun and take care

The NOVA has a built-in capability, but somehow I think a vacuum chuck on a
2" recess isn't going to instill confidence in the guy working a 12" bowl.
