Charlotte - can you ask you Dad about model steam governors where they can be found and if he knows of any kits that are available. I am building a scale man cave (1/12 scale) so when my granddaughter plays with her doll house I have some place to play with my scale machines to make my own scale parts. I have got most of the PS Model scale machine kits and am build their diorama for displaying my work. It would be nice to have control over how fast the main shaft spins so that the machines run at a realistic speed.

I saw a photo of a green twin oscillating steam engine on the Preston Services website a few years ago, and a Canadian buddy of mine challenged me to make one. Long story short, I built a foundry, used a 3D modeling program to model the engine using 3 photos, made the patterns, and cast the parts for a 60% scale engine. I recently got the engine running, and it can be viewed here: https://www.youtube.com/watch?v=UxIZ4iuhLyM The plan at this point is to finish the painting work on the engine, and publish it in Live Steam and Outdoor Railroading magazine. It was a long journey to learn the foundry work, but I was able to cast some of the parts in gray iron, with the remainder being cast in 356 aluminum.
