  1. I think the polishing is only removing tiny amounts of glass at a time John... And it is on the scale of a few atoms I believe, so it can be polished quite a bit before the glass will get noticeably thinner, or unusable. Once Damian has it all to the right spheroidial shape he will then figure it to a parabolic shape. I think I am right :)

  2. Ron and John thanks for trying to help us non-glasspushers to understand a very intricate process but I think I'll leave the mirror grinding and figuring details to experts such as yourselves, Damian, and the other very knowledgeable glasspushers on here :) I'll just enjoy the thread all your posts and the progress it shows Damian is making, and I am sure when Damian finishes the mirror I'll get to have a look through it (him being one of my best mates an all that) ;)
