Ok - take the bowl off the chuck. Tighten the chuck until the dovetails
touch and all match. You might have one a thread out or in from each other
and be cutting a programmed oval.

I've been having trouble getting my bowls to turn true lately. Not a
lot of wobble but enough to require a lot of sanding on opposing
sides. I'm wondering if the play in the slides on Nova G3 chuck are
to blame. It seems to be getting worse over time.

Any suggestions?
