An improved automotive valve surfacing machine has a variable speed chuck assembly driven by a variable speed AC gear motor. The speed of the motor is set by a potentiometer. A one-way clutch assembly located between an output shaft of the variable speed motor and the chuck assembly provides a release mechanism whereby the chuck assembly may be freely turned in one direction, using a knob located at one end thereof, to visually inspect the valve surface being surfaced without any drag due to the gear motor.

A damper for use with work arbors supported at only one end is disclosed which acts to reduce harmonic vibration and chatter as the arbor rotates and a cutting tool operates on the workpiece. The damper consists of a damping collar, with an interior radius greater than the exterior radius of an associated spacer, which freely rotates on that spacer such that the collar rotates independently of the work arbor at a speed of about 66% of the arbor's speed and acts to suppress undesirable chatter, and harmonic vibrations.
