This single-cylinder, reversing steam engine was built from bar stock using Sherline miniature machine tools. It was scaled up two times from the plans for a smaller engine that Les had built, and which ran particularly well. A small generator rated at 4 volts/1 amp at 3,000 RPM is powered by a belt drive off the steam engine’s flywheel. When in operation, the generator lights a small streetlamp on a post.
