These lapping blocks allow you to smooth and polish the surface of the pistons without removing any material from the inside of the valve casings. Ideal for fitting replacement valves, or re-surfacing newly repaired valves. Hold the valve stem in a bench motor and place the lapping block around the piston, this can be coated inside with lapping compound or whichever abrasive you deem appropriate.
