The problem with thin mirrors is that they flex more easily during grinding and polishing, making it hard to achieve the required surface precision. They also need a more complex mirror cell (additional support points). Plop is a useful software to let you calculate the number of points needed based on the diameter and thickness of the glass:
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 of them came from industrial junk yards.
The mirror machine came to me as a result of astronomical horse-trading, swapping a large GEM mount and a 8" Newtonian OTA for the machine as it was and a start kit consisting of two 6" blanks and the grit, rouge and pitch to manufacture a mirror.
