Chris:

I don't know if this will help or not but those of us who have had any
'learning' from John Jordan (or from several other big name turners)
ALWAYS start everything between centers. Once you drill your hole or
make a flat and attach a faceplate, the center and orientation of the
work is cast in bronze. If you start between centers it is not since
you can, as the work begins to take shape, move either the headstock end
or the tailstock end. When doing a natural edge bowl where you want the
wings symmetrical, for instance, you will almost surely need to do this
at least once.

I like to get the bark off without any damage to the wood, so I can choose
the right spot to drill the chamber to tighten it on my chuck. The thick
bark quite othen hides a hole or other surprise, which can be used if
noticed or destroy a design if unseen.
