[ATM] 8 inch gregorian mirror

["Wayne Hilliard" <woodycxd@comcast.net>]

Gentleman,
      Its been a while since Ive posted here all though I do read it
periodically. I have a question, I'm figuring and 8 inch mirror for a
Gregorian I'm building. I went ahead and removed the core from the center of
the mirror. It polished out fine with a full size lap that I trimmed the
center facets out of. I'm debating what the best way to figure this is.
Regular figuring stroke or some other combination there of. Ill be
interested to see your comments. I do realize that I should have left the
core in but that's water over the dam so to speak.

Thanks all in advance.

Wayne Hilliard
