If anybody’s curious, here’s a video update on my steam engine project. I upgraded the oil burner, although I’m having trouble getting it dialed in. I also decided the heat needs to transfer through the wall of the boiler better, so I welded numerous little tabs on it to create a sort of reverse heat sink. It does run, as you can see in the video (which for some reason I can’t post directly here). This link takes to you Youtube for a 1:10 expo.
We’re having some fun now!
