Mirror Grinding Machine

2015-8-14  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

Grinding Machine for Large Telescope Mirrors

2020-11-1  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.

2021-2-1  The I.A.U. named asteroid 17823 Bartels discovered 1998 by J.M.Roe in recognition for my contributions to amateur astronomy. Making is the Key to Knowing. A telescope mirror is arguably the most accurate surface made by human or machine. Amazingly you can grind a mirror by hand and make a telescope with simple hand tools.

The Design Mirror Grinding Machine

2015-8-13  The Design . I began by measuring the sizes of what I already had, a 1/3 hp 1750 rpm electric motor and a 25:1 geared speed reducer. Then I took a rough cut at the MoM-20 H-frame and placed the motor and gear box on it. Lining up the pulleys, drilling holes for the mounting bolts and making sure the belts would clear everything drove the design

Build your own telescope part 1: The mirror Thomas

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.

2016-4-6  Before starting the grinding operation keep at hand tow pieces of cotton cloth (about 10-20 cm in diameter or side), a small tray or basin for carrying the mirror, a basin of clean water, and a heavy weight (4-6 kg for a 20 cm mirror, 2-3 kg for a 15 cm mirror, say) wrap in plastic or sheets of newspaper.

Dick Parker's Telescope Mirror Workshop: Cassegrain

2010-8-14  The design must also account for back focus distance or the distance from the primary mirror to the focus plane behind the telescope to accommodate the focuser, star diagonal, and eyepiece. Considering the primary mirror focal length, the shortest, or fastest focal ratio generally accomplishable by an advanced ATM is f/4.

Ritchey Mirror Grinding Machine National Air and

2021-2-16  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 initially intended for the Yerkes Observatory.

Design and verification of a robust secondary mirror

This work presents a developing design of adjustable supporting mechanism of secondary mirror for airborne Cassegrain optical remote sensing instruments. Several datum surfaces and shims have been designed in this mechanism, shims and one of structural parts can be released and are properly grinded to the desired thickness. The proposed mechanism has been verified by an experimental model. The
