What they don't do, but my mirror making mentor David Sinden http://www.britastro.org/iandi/mariot04.htm did: Rather than clamp his mirrors in position he attached a threaded plate to the back with pitch. It was very neat, and the 'nut' screwed onto the lower spindle when on the bottom, and captured a peg coming down from the upper arms when on top. I'll draw a diagram! |
Wouldn't the pitch move with the summer heat making the grinding uneven?
