A larger than 20" bowl turned without tailstock support on a Oneway
chuck, and as several turners have tried to tell a certain person that
there is NO Mangled or Crushed or Chewed up wood, it does not seem to
sink in, so for all who would like to assert themselves of the facts
without the BS, have a look.

I might be missing something here, but don't Oneway jaws only have the
wavy profile on the inside for gripping tenons? As far as I can see the
outsides are perfectly circular, which is what you used here for
gripping the recess.

My feeling is that while the wavy shape of the Oneway jaws is a useful
idea, the power of their grip is achieved as much by the ridged surfaces
which bite into the wood, as much as it is to do with the profile.
