My Mirror Grinding Machine. For a long time I've wanted to build a machine for grinding telescope mirrors. Dennis Rech's M-o-M designs finally inspired me to just get up and do it. Over the years, I'd been collecting motors, gear boxes, pulleys, etc. Most of them came from industrial junk yards.

Grinding Machine for Large Telescope Mirrors. I designed and built a grinding machine for mirrors up to 42 inches [1.1m] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work. The machine can also work smaller mirrors if the drip pan is moved to the fast shaft on ...

The November 1974 issue of Sky Telescope (page 325) carried an article by Eric G.H. Mobsby of Blandford Forum, Dorset, England, describing a method of testing medium and long focus mirrors with a special inverse grating that can be interpreted with the ease of a Null Test. Robert A. Cox, then Co-editor of the Gleanings for ATM’s column ...

George Willis Ritchey built this mirror grinding machine at the Yerkes Observatory in Williams Bay, Wisconsin, in the late 1890s. Under the sponsorship of George Ellery Hale, the machine was used to grind a series of telescope mirrors starting with a 24-inch and then a 60-inch mirror for a telescope

Jul 21, 2006 While it’s true that the aluminized surface of a telescope mirror will deteriorate over time, there is no hard and fast rule about how long this will take. Some coatings last only a few years, while others will outlast you. Indeed, the coating on my very first reflector telescope

Mirrors can only be made with Special Precision Equipment in Expensive Factories or Labs; Not True! Telescope mirrors can be made in your kitchen, basement or garage with nothing more than the mirror blank and a second piece of glass (called the tool) to rub the mirror

Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror

telescope mirror grinding machine based on Dennis Rech's M-o-M 20. CNC telescope mirror grinder. CNCZone. Dec 6, 2006 Rough and fine grinding the mirror is about half the work. Polishing is the other half. Testing and figuring makes the third half. I've ground a few by hand, not to say I know anything about machine grinding.
