I got such a kick out of Brassy that I drew up the plans and posted them elsewhere on this site. It was my fourth engine and the second of my own design. (None of these are really my own design, in that they all follow the same principle of operation. What I mean by “my own design” is that I did not follow someone else’s plan. I’m sure you’ll find other steam engines that look like this one.) Brassy is a single-action wobbler with a 1/4″ bore and 1/2″ stroke. She’s been so much fun to operate and show to friends that she’s nearly worn out. Here’s a link to some other people’s versions.
