2 Paste lapping tools for valves + Quick lapping tool with suction cup
Grain 80 and Grain 180 metal pot + support with rod and feeder for rapid valve honing
Several suction cup sizes to suit different valve sizes.
Apply some abrasive paste to your valve head, and break in your valve in its seat by turning it with the weight to be driven with an electric drill.
For the most watertight lapping, we recommend that you do one pass with 80 grit and then the finishing pass with 180 grit.
