Re: ATM Figuring question

Grinding and polishing will work with this stroke, but don't be afraid
to allow a little variablilty in there, it helps ensure a good sphere.
Figuring is another thing though. For figuring, you'll want a thicker
mixture of CeO, and will operate with less trips around the mirror. More
tool on top will help to prevent tde. This works for me anyhow.  When
you get to the point of figuring, post again on the subject and we can
walk you through it.
