I know that people use vacuum chucks to attach a bowl to the lathe so that the bottom of the bowl can be finish turned (i.e., removing a tendon or decorating the bottom).

Here’s my question: can you use a vacuum chuck to attach the bottom of a finished bowl to the lathe (assuming the bottom is nice and flat) so that you could — for example — freshen up a friction polish on the bowl or apply a fresh coat of hard wax to the bowl?

Thanks,
