Want to grind a mirror? We have two 8 inch mirror blanks (one is pyrex, the other may be) and associated tools, several interesting 6 inch blanks that may have been flats, but could be mirrors. A 10 inch 1.75 in thick blank that is about polished out and ready to coat, and a 4 inch mirror (good) and a somewhat mistreated 6 inch. And we have grit and such.
Cost will be minimal.
email chuck if interested.
