I was up in Grass Valley California visiting my brother over the Thanksgiving weekend and we went to local museum at the Empire Mine. (Click here)
I always love a good museum and this one was one of the most interesting. But when I walked into the machine shop it won the prize for the part I liked the best. I have seen old shops with a few belt ran machines but I have never seen anything like this.
Every machine in the building was ran off a single motor up on the ceiling. Now, back before electricity, it was steam driven, one steam engine.
