• Mirror Grinding Machine

    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.

    IntroductionGeneral InformationTelescope Mirror MakingOptical TestingATM Resources ReferencesA lot has changed since Russell Porter wrote those words - today the \"average workman\" can afford to buy an already made telescope and Dobsonian mountings are very popular. Much is also unchanged - mirror grinding techniques are very similar to those written up by Porter and Ingalls in the 20´s and 30´s. Many amateur astronomers still choose to fabricate their own instruments, for the pride of accomplishment, the gaining of knowledge and the insurance of quality. Telescope making is at the he...

    Rough Grinding The first milestone is putting a curve into the mirror face. The curve's depth dictates the mirror's focal length. The curve should be spherical. Creating the curve can be done by several methods: The curve is ground into the mirror face using a grinding tool. The curve is pre-generated for you.

    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 (e.g. F/D = 8) will be performing very well on planets and the moon.
