The M-o-M is a marvellous machine due to its simplicity and yet refined design. It is extremely flexible accommodating mirror sizes from 4 inch up to 20 inch with slight modifications and can be used for all three steps necessary in producing a mirror. That is you can use it to grind, polish and figure your optics.

One problem I face during construction was that all measurements and plans are done in imperial units since the machine has been developed in the United States. I had to make a choice between building using imperial units with all the problems associated like hardware and machine standards, or convert the plans and metric units.

The chips arent too bad, and arent really a problem at all if I am cutting disks to fuse together. If the disk needs to be chip free, I simply cut it a little oversize and then grind down the edge to size erasing the chips along the way with the edge grinding attachment. Here is a photo of the machine set up to cut another glass disk.
