Abstract

A system for polishing an outer surface of a specimen, the system including a motor and a rotatable shaft extending from a first end of the motor, wherein the specimen is removably attachable to the rotatable shaft, a safety cover configured to at least partially surround at least a portion of the rotatable shaft, wherein the safety cover includes a top panel, a first side panel and a second side panel spaced from each other across a width of the safety cover and extending downwardly from the top panel, and at least one aperture extending through at least one of the first and second side panels. The system further includes an abrasive material insertable through the at least one aperture so that the abrasive material is positionable to contact the outer surface of the specimen.
