Starting last winter I began constructing a steam engine from a set of Model Maker Plan Service blueprints and solid billet. I have been deviating from the plans on several points...I am doubling the size and modifying the design to add reversing linkage. I have been working up the modifications in Solidworks to review the changes in 3d simulation before committing to actual construction of the various parts. The overall size is approximately 11" tall with a 1.5" piston. It is of a rather odd design in that it has a closed crankcase instead of the usual open design of most steam engines

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.
