This process of Lapping is used on musical instruments as well to fit a trumpet or other piston/valve into its own personal cylinder ... uses the surfaces that will be touching in the end, or living together, and a lapping compound (sometimes even toothpaste...), to bring the 2 surfaces shapes closer together ... then uses a valve oil to seal and lubricate the result. These valves require air tight fit (seal) and a friction free movement (lubricated) for rapid repositioning during making music. Just some comments on Lapping two surfaces ... which I have only seen done ... I think I'm going to leave my QS Dual 1GHz alone, unless it starts having kps I cannot explain otherwise ... was considering "preventive maintenance" idea of replacing the thermal connection being discussed herein ...
