Hello. I am a young person who is interested in steam and everything to do with the railways. I would like to build a small 7.25in gauge steam locomotive but I am not sure where to start. Is there any chance you could give me any tips to do with this? I would like the locomotive to be to my own design but still be cheap to build and powerful.
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.
