A friend has a 10" f/2.9 mirror that was mistakingly parabolized by the maker. Additionally, it has some minor scratching at the center. I am going to attempt to return it to a sphere for his purpose and eliminate or reduce the scratches. Would it be best to make a dental stone tool, populate with tile and return to 320 grit or so, or attempt to polish it out. The origional tool is missing and I have a 10" tool that I have made a lap for and started the polishing process, but I'm wondering how much time this may take with cerox!!
