A device for automatically sizing (thickness control) a workpiece of a double wheeled lapping machine, during the lapping process with simultaneous runout of the lower lap compensation. The device provides an annular ring attached in parallelism to the upper plate, together with a roller follower having contact with the under surface of the ring, with the follower pivoted upon an adjustable mounting arm attached to a vertically extending stationary post mounted beyond the circumference of the ring on a supporting shelf formed as a part of the machine casing. A movement responsive probe is in contact with the follower and responds to any deviation in flatness of the workpiece as it is transmitted therefrom onto the lapping surfaces of dual lap plates during the lapping thereof.
