Eric Ent from work came over with his model steam engine. He got it running recently and I found it fascinating. We thought trying the propane torch would really make it move, and it didn’t disappoint. It is a Wilesco steam engine, possibly a D4 model.
It worked much better with the propane torch, but we didn’t want to risk breaking the boiler due to excessive pressure. The whistle worked a little, but seemed to require more pressure that we wanted to provide. I spent the next few days researching steam engines, but it seems like it would take too much time and money for a full time hobby!
