[ATM] turntable for grinding mirror

[polaris@gsinet.net]

Thought I'd throw this out there .... 

planning my next grinding project, a 11" f/6 or so.

  Anyway, to avoid doing the "barrel waltz" I was thinking of making a motor-
driven turntable to grind on.  The table would slowly rotate as I ground the 
mirror.  Of course, I'd still have to periodically give mirror a turn, as 
always.

  The advantage of this is I can grind on a fixed work location, even sitting 
or kneeling.  I won't have to make a grinding table to walk around.  Also, I 
am thinking it may help with generating the surface of revolution.

  Is there a problem with doing this?

Thanks,
Rob
