I'm a relative newby to turning and have a problem for which I don't see
an easy solution.

I've just turned a bowl which is 6 1/2" in diameter but with a 4" opening.
The bowl is finished and it is now time to part off the tenon/spigot. My
problem is that my OneWay 4-jaw chuck doesn't open wide enough to hold the
bowl by its opening, and the Jumbo Jaws don't close small enough to hold
it by the opening. The outside from the opening on top to the sides is
too high to be caught by the rubber jaws on the outside.

What is a reasonable solution? Some sort of jam chuck on a spur and hold
the tenon by the tail stock while I part it off?

Thanks.

Hello. Use your chuck to turn a jam chuck held in a mortise that will wedge
into the opening in your bowl. Alternative is to make a larger one and
wedge the bowl into the opening in the jam chuck.

Or turn a hollow ring and hot glue the four sections you cut it into onto
the jaws, or use double-stick tape. Then chuck up.

Next time consider a mortise that doesn't have to be re-turned.
