In addition, a great deal of money will be saved: a finished 24" scope will set you back $7,000; grinding your own mirror and building the mount yourself will cost you $2,000. Amateurs have made mirrors up to 41" by hand. A grinding machine relieves the labor, but is not necessary. A 24" is the largest you can comfortably do solo.

Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial for the hands of a musician.

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 Telpe Making" Book 1. A bowl which rotated was fitted to the spindle. I also built another machine of the same type.

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.

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 telpe (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.

Typically, it is best to have the position of the lap overhang the mirror by 1/6 the diameter of the mirror. With my mirror being 16 inches and the lap being 12 inches in diameter, this equates to the lap overhanging the mirror by 2.66 inches. Most of my polishing was done with the lap overhanging the mirror by 2.00 inches.

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 is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion glass like Pyrex has no practical …

Basically there are two types of grinding/polishing machine. The 'traditional' type which involves the mirror rotating at a relatively slow speed, a few rpm for a big mirror (16-20 inches) with the tool moving across the mirror, from side to side, at a higher rpm depending on the size of the mirror and/or tool.
