Hello. I recently received my diamond pastes and have had some success using a leather band and microfiber along with the pastes to reduce and (in some cases) remove scratches from the lenses of various watches. I am wondering now how to bring the process from hours to minutes. I want to be able to polish metal bands as well, but glass & crystals are my main focus. I have found that all the rorory tools run at 10k to 35k rpm. I know i need more like 1k to 7k rpm. Are these possible to find? does anyone have other suggestions? I looked into bench polishers. These look great for bands, but i dont have a garage and im not sure this is the best option for removing scratches from crystals and glass lenses. what is recommended for doing this at home? thanks in advance.
