unfortunaty finances are tight at the moment but will hopefully be able to get things going in the new year i plan to document everything so will keep you tuned in :)
I have made a 12.5 inch (318 mm) mirror. I am also working on another as well as two flats of the same size. I may go larger, but weight and portability become factors.
Yes, I think there are some mirror grinding seminars nearby it is just a matter of me going to one. One more question, After you have grinded and polished the mirror, how do you apply the reflective layer?
@wannab009 I either go to a mirror class in Washington DC where they have a vacuum chamber and coat the mirror there or I send the mirror to a commercial coater in Skokie Illinois for coating with a proprietary metal that he calls beryl. The coater is Clausing Optical coatings. You can reach them through Google. Best regards, Francis J. O'Reilly

Interesting, It must be awesome to use your own grinded mirror and have it perform well. I bet there is an immense feeling of satisfaction..
