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

Carson, I don't understand why you want me to contact you off site. You can also send me a message though out private message system.


Also I notice you have made the same request of people on other forums.


If you need pictures I can post them. Remember I am not a machinist.
I can confirm that the answer you got on HMEM is correct. The piston has 3 shallow oil grooves.
I had the piston out briefly a few years ago and that is my recollection. On HMEM, most of the members are machinists.
