Seater Stone
New brushes must be beveled and concaved to conform as closely as practical to the curvature of the communicator (DC) or slip-ring (AC). The seating stone is a non-conductive stone (NEVER USE EMERY OR ANY SYNTHETIC OXIDE TO SEAT BRUSHES!) that is pressed lightly on the communicator near the leading edge of the brush.
