So, I had a wild hair. My grandfather worked in the mines of Butte, MT. As a child we went back to Butte almost annually. I decided to design and build some ore carts. I did these as I could design the models using only a scale and pencil. I designed both with a 1" gauge and the intention of using HO wheels. I may design some wheels to go with. I do need to design the tilt lever to finish the first model. The first picture is the prototype for the first model. I may try to design the compressed air loco in the second picture (From the World Mining Museum, at the Orphan Girl mine Butte, MT. My grandfather worked in that mine among others).
