19/08/2019· I've decided to build my own fixed-post glass grinding and polishing machine.

The tool is always smaller than the mirror if a concave mirror is desired. Tools of 50% to 80% of the mirror’s diameter are normal. Tools of less than 50% diameter may cause problems while grinding, although,
