One as the mirror, and the other as the tool. If you have such a kit, save the second glass, and make a tile tool. Tile tools grind faster, and you can make 2 mirrors instead of one. Or you can share the costs of a mirror kit with a friend and make a mirror each.

Another surprising advantage is that hand made optics (if guidelines are followed) tend to have a higher surface quality than the mirrors polished by industrial machines. Building a reflector telescope can be decomposed in 2 steps: make the mirror and build the tube/mount.

I know a guy who built a large trepanning saw and cut mirror blanks out of thick scrap glass. The machine was huge, took forever to cut the glass, and finding thick enough glass was very difficult. I had always thought it might be simpler to make a mirror blank by fusing together a stack of thin glass disks in a kiln.

Re: Building a fixed post mirror grinding machine. Update summary: Lots of work to get to this point. Things I need to probably change or fix: My gearing of the DC motor. I will need a slow speed for polishing (5 rpm), and faster speeds for hogging out and fine grinding (15- 30 rpm), so likely need to think about adding a gear reduction.

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.

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.

Grinding On the picture below the machine is fine grinding an 8 inch mirror with an 71% tool (143 mm diameter) and 9 micron aluminium oxyde. The bent lines on the mirror are the effect of the tool turning - with respect to the mirror - faster at the central part of the mirror as compared to the edge zones.
