Grinding telescope reflectors of 15-inch diameter and over makes it necessary to employ a motor-driven turntable. Small mirrors are generally ground and polished by rotating the tool, fastened to the turntable, and working the mirror blank by hand either in straight or in circular strokes over the tool. In this case the overhang of the mirror.

Gordon Waite sets up his fixed-post mirror grinding machine to begin rough grinding on an 11 f 4.3 telescope mirror. He uses a grinding tool made from dental plaster and steel pieces to speed up grinding. Gordon shows the setup for spin grinding at high speeds and with added weights to get the job done as fast as possible.

Nov 01, 2011 Basically there are two types of grinding polishing machine. The ‘traditional’ type which involves the mirror rotating at a relatively slow speed, a few rpm for a big mirror (16-20 inches) with the tool moving across the mirror, from side to side, at a higher rpm depending on the size of the mirror.

Telescope Mirror Making: Part 3 Rough Grinding

A good starter size is the 150 mm (6 ) mirror. A 200mm (8 ) will also work. Most ATM books and websites recommend a Pyrex mirror blank, but in my opinion, annealed plate glass is better for this first, learn and practice mirror.It is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion glass like Pyrex has no practical (visible at.
