I put on a coat of paint on my Modified Coomber steam engine.

You can find the plans and CAD models here:


Here's the finished engine:

I finally finished my "problem child" Coomber. I followed Vederstein's plans. All through this build, I was encountering small "teething" problems, mostly because I didn't follow instructions!!! When I assembled all the finished parts, it would rotate very freely with no air. Introduce air and all kinds of binding problems. Got them fixed. Took it all apart, painted everything and reassembled. Again binding problems with air. Finally fixed it and finally got it to run under power. It's probably going to be the only time it runs under its own power as I'm not going through this again. Now it looks great on my bookcase shelf. I've included 2 videos, one running before painting and one after.
