Hi Rob,
Post a question in the ATM section of the “Lost in Space” forum. :lol:

Mark Suchting reads that forum, there’s also a guy from NZ who sells some blanks and there’s a long running sticky called, “Are there any mirror makers left in Australia.”

What size are you looking for?

Rob,

What size are you after, and out of interest, what are you planning to build?

I have a 10" corning pyrex blank and a 10" composite plate glass tool multiple sheets of plate glass glued together with epoxy. i don't believe that Corning pyrex blanks are available any longer, they stopped making them many years ago. This was part of a special order direct to corning made by a telescope making group. The 10" is ground down to fine grit (1600) at f6. However, I later acquired a complete 12" f6 Royce Conical mirror and secondary set. So I stopped working on the 10".

Looking to preferably build 10" f5 but 8"-12" is ok. Building More for a learning experience , I find 10" f5 practical for use or even 8"
