Abstract
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.
