Hi there Arch

Arch ,my opinion, if everything's equal, the larger surface has the most
strength, that's the outside.
The other thing is, give me the oneway chuck jaws, they hold better
hands down.

Have fun and take care

To turn endgrain N.I.Pine, I use a faceplate, waste some wood and
complete the piece without reversing. It's academic, but If I did use a
scroll chuck on softer timber would it not be better to expand the jaws
toward the stronger periphery instead of compressing toward the log's
weaker soft center or mushy pith? I'd think that compressing a tenon or
expanding into a dovetail would largely depend upon whether the center
or the periphery is strongest.

For first holding on/in a dovetail which doesn't allow the blank to
reach the chuck body or base of the jaws, what determines the blank's
axis; the axis of the dovetail walls or the face that the jaw's forward
rims register against? OK to sigh, but don't groan.

Turn to Safety, Arch
