Miniature generator set

[mklotz]

I bought a miniature generator kit from PM Research...

and after building it decided it needed to be operated by one of my steam/air engines. The result was this generator set...

The engine is one of Elmer Verburg's designs. It's two cylinders, single acting. This allows both cylinders to be serviced by a single D-valve on the top of the block. In the first picture above you can see the eccentric and pivot arm assembly that drives the valve. The steam chest is covered with a plexiglass cover so the valve motion can be seen. When running on steam this cover is removed and replaced with a brass cover.

Here's a close-up of the generator...

Although it's not terribly obvious in the photo, the light bulb is glowing brightly.

Plans for building this engine are available here...
