Описание: The 12" mirror is taken through the rest of fine grinding, going through 12-micron, 9-micron and 5-micron stages. Gordon shows how to do maintenance on the ceramic tile/dental plaster grinding tool. He demonstrates methods for deepening the mirror faster. Plus you will see tests Gordon uses to check for grinding status and to see if the mirror surface is becoming more spherical.
