Swap a 250mm plate glass blank for a 200mm
Hi,
I have a old plate glass 250mm x 30mm mirror which would make a nice blank to swap for a old 200mm mirror blank in good nick. Don`t care if it has been ground or not as long as it isn`t too rough.
This mirror was figured to f/10 but not a good figure. I have cleaned up the edges as it was real rough and now is within +/- 1mm of a nice round disk. Took a hours work to get it nice and is beveled ready to grind away on.
I can supply a pic if you want one.
cheers Gary
