2007-2-13 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

2019-8-19 Re: Building a fixed post mirror grinding machine. I I had a nice piece of 3/4" stainless dowel that was begging to be used. So I bought a cheap pillow block to provide the locator for the metal dowel, and then drilled the overarm to fit. These pillow blocks are $8 and come complete with a locking collar - great deal.

2015-4-5 Mirror-o-Matic was designed to be a very low cost astronomical mirror grinding, polishing and figuring machine. Its attributes are: 1. It can be built for somewhere between $200 and $400. 2. It is constructed of hardware store items and it needs no machined parts. 3. It is constructed primarily of 3/4 inch plywood and has few close tolerances. 4.

2015-9-30 Theories on designing a robotic mirror grinder. - posted in ATM, Optics and DIY Forum: So I have been thinking and doing some preliminary design work on a robotic telescope grinding machine with the intent to grind a 12 inch parabolic primary mirror for a telescope I intend to build. I have been trying to understand the mechanics behind grinding a telescope mirror

2013-2-26 I borrowed a few ideas from the Mirror-O-Matic mirror grinding machine, particularly how to mount the turntable on top of the pulley. Anyone building machinery for cold-working glass should have a look at the MOM web site and plans. There are lots of good ideas there. The large wood circle will become the base of the turntable.

The mirror or lens grinding machine is a masterpiece of mechanical engineering. It has several gears in mesh at all times and also has several variable settings built into it. This machine was most likely designed by Leonardo while he was either investigating the different ways that light reflected off things or maybe he was planning on ...

On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon. The theory behind grinding is that you can remove glass as long as you use a material with a higher hardness. Telescope makers use

Documenting the telescope build, including mirror grinding and figuring, and construction of the Renegade telescope body. Part 1 includes prepping the mirror for grinding, spherometry on the molded blank, fabricating a steel/plaster grinding tool, and setting up the fixed-post grinding machine for rough grinding operations.
