Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I was the 1 that 1st mentioned it the engines running in the wrong direction I did notice that they do sell replacement camshaft I think for $36 I do plan on purchasing 1 or 2 and seeing what I can do experimentation wise at some point in the future. While you have apart it would be a good time to install some 1/32 inch spacers made from teflon sheet to prevent the piston pins from scoring the cylinders. Can you tell me the diameter of the piston pin? I have not disassembled mine yet. I want make punch for the teflon discs. I have the teflon material.
