Re: [ATM] turntable for grinding mirror

Brent,

If the primary reason for turntable was avoiding barrel dance than rotating
platform will be sufficient. No motor needed. It is easier to take care for
"averaging" if tool and mirror are rotated by hand than if one is rotated at
the "mercy" of the motor. You will soon loose feeling where
you are. Every stop or change in speed of hand strokes will change mutual
relation tool-blank in unpredictable way and consequently destroy your
control over it.
If you are going for motorized turntable than it will be
only small effort to add  overarm (motorized or not).
(In my opinion of course.)

Vladimir.
