One of the reasons that I went to a vacuum system was that when a bowl is
nicely
warped, it won't sit flush in a cole/jumbo jaw setup... which makes it
hard to
hold and harder to do anything to the bottom of the bowl..


LOVE that pin chuck. No fooling around. Re-turns are on center and capable
of being held there by the pin chuck for prefancying the bottom before
reversing if you care to after rounding the outside.

Plus, it's there when you reverse to become that third hand and the
tailstock your vacuum chuck.
