Re: [ATM] Buehler EcoMet #5, 2 speed grinder polisher

[William Marriott <bmarriott@pacbell.net>]

Hello Carlos;

Welcome to the list.  As to your polisher/grinder you
can use, it looks like it might work well.  Checking
Buehler's website, I cannot find specs for this model,
so it must be an older version.  If the turntable
turns, and has a reasonable amount of torque, it would
be great, especially if you can slow the spindle down
to 1-4 rpms.  Since it does not appear to have an
overarm, you must stil do the hand work, but with a
smooth running slow spindle, you can produce great
telescope optics that way. 

What is the diameter of the plate?  What size of
mirror are you contemplating?
