[SEL] rear tool post...deviates!!!!

[Ken Christison]

Peter,

I still don't see any advantage to simply changing the direction of the
force on a revolving piece since the force is the same regardless.
Seems like a follow rest or center rest is the only way to minimize
flexing.  Is there any other reason for this technique?
