A few weeks ago, my friend Bruce sent me a link about a museum in Carlsbad that exhibits working models of airplanes, boats, trains, and so forth, with miniature working engines. Since I was headed to San Diego this weekend for the Towerthon, I thought this might be a good side trip.
The museum is in an unassuming industrial-looking building kind of off the beaten path. Fortunately, I had Waze to tell me how to get there, or I would have had trouble finding it. When I got there, I went inside, and immediately saw the featured exhibit. A tiny scale model of a supercharged V-8 engine. Apparently, it’s fully functional. Yikes. I wandered around the museum, looking at all the tiny engines. There was a board with some tubes attached to it that said it was three miniature steam engines. They were so small I had to look carefully to see them at all. At the back of the museum, they had a model of the Wright Flyer, and a working model of a P-38 fighter. Then, along the back wall, they had a display of miniature steam engines, all hooked up to a compressed air supply, and the sign said that they would run the engines and give a tour of the machine shop at 2:00. Since that was just a few minutes away, I decided to stay and see it. When the time came, they turned on the air, and all the little steam engines started running:
After looking at the tiny model of the Titanic’s engine, we went into the machine shop. The first stop was the “Do-Nothing Machine”, which was featured on Roadside America last year. Our guide described it as “a cat toy for humans”. It was pretty funny:
Next, they showed us four different tiny working engines. There were two different gasoline engines, one Stirling engine, and a fourth of a type that I didn’t recognize at all. Here is the first gasoline engine running:
The last part of the tour showed us another radial airplane engine that they are building there. They even had a model of the model to show us how the inside of the crankcase worked. I’d always wondered how cylinders in a circle could turn a crank, and now I know.
This was one entertaining little museum. At least for anyone with a mechanical and geek bent.
