mill work that requires great accuracy. An edge finder helps in finding the edges. 800-1200 spindle RPM is recommended. To use an edge finder, slightly offset the two halves so they wobble as they spin. Slowly move the workpiece towards the edge finder. The edge finder will center itself, then suddenly lose concentricity. The digital readout tells you the position of the spindle
