Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.

knurling moves metal up from the piston skirts making the piston bigger you need a piston knurling machine to do this then you need to fit them. i do this with a file and a hand sanding block with stick it 80 grit paper. this takes some time to do and would not do on a set of 120. cast piston just bore the next size up on the piston rings there file fit rings you can get some rings there 035 and 065 etc you file them to get the end gap you neededIrish Diplomacy ..the ability to tell someone to go to Hell ,,So that they will look forward to to the trip
