Use a Split Mandrel for Finishing Round Bezels


A bench jeweler typically uses a split mandrel to sand and finish the inside of a ring. Various grits of abrasive papers can be cut to size and inserted into the slit of the mandrel, where they are held by friction during the rotary filing process. With minor modification, you can use the split mandrel as a holding device to finish round bezels and other small jewelry components quickly and consistently.
