Some bowls dry with a usable dovetail pretty much intact, some wind up
with an oval hole. I often chuck them in the cole jaws and re-do the
dovetail before finish turning. Recently I made a jig to round up the
dovetail with a router. This requires a 15 degree dovetail bit but has
worked well for me. If anyone is interested I can do the pictures &
description.

Looks like a good idea, if I could find a router under all the bowls and
shavings.. lol

Personally, I'd rather do it on the lathe, feeling that the end really would be
true to the bottom... I'd be sort of afraid that your new or cleaned up recess
might not be the center of a warped bowl any more, and the bowl would really
spin awkwardly..

I find that it's pretty fast using a jam or vacuum chuck and the live center
without the point... holds the bowl and is adjustable for allowance of warp and
lets you do a little truing and cleanup while you're at it.. YMWV
