How I built an edge grinder for telescope mirror blanks.

The grinder is held onto the other side of the hinge with a bolt through the hinge into the handle socket, and a couple of pipe clamps. Some small wooden wedges were cut to fit between the side of the grinder and the hinge to allow for the curved profile of the grinder body.

Astro-Tel - Mirror grinding machine

MIRROR GRINDING MACHINE. I made my first mirror grinding and polishing machine over thirty years ago. It used the working principle of the machine illustrated at "A" Fig.3, Page 163, "Amateur Telescope Making" Book 1. A bowl which rotated was fitted to the spindle. I also built another machine of the same type. Also a Hindle type machine for a southern firm to grind and polish 12.5" mirrors ...

Leonardo Da Vinci's mirror making machines

One machine is designed for grinding concave mirrors of small focal length. The other machine, a much larger piece to implement, grinds mirrors of large focal lengths. Though Leonardo da Vinci creates sketches of mirror grinding, one crucial and logical question to ask is whether he used such mirrors in his artwork or drawing. On this subject, a bevy of scholarly research has surfaced both ...

You may notice that many commercial telescope advertisements proclaim they use "Hand Figured Optics" - in fact this is one of the best and least expensive ways to get an accurate surface on a mirror - most machines just can't hold

Joy of Mirror Making: Fine Grinding - BBAstroDesigns

For large thin mirrors, say 12 inches [30cm] or greater and 1.5 inches [4cm] or thinner, the mirror back must be ground flat, or at least regular in shape before beginning fine grinding the mirror's face. Cast a tool specifically for the mirror's back, and grind with 220 grit, inspecting for low unground spots. Grind until they disappear. It's OK for the back to be ever so slightly spherical ...
