A Horizontal Experience

[Richard Horne]

This is my second engine model, a horizontal steam engine with 1" bore and 1 1/2" stroke. It was built from PM Research castings and plans using a small lathe and mini-mill and required about six months of intermittent and part-time work. The original PM Research flywheel was too spindly for my taste, so I substituted a heftier Stuart 5" flywheel casting. I also built a fly-ball governor from Stuart drawings, with modification to use a simple cylindrical control valve rather than the awesomely difficult flapper valve in the original design.

Below is a video showing the engine running on low-pressure compressed air.

Very nice job! And I do like you choice of flywheels. I always thought that PM Research engine would be more popular if they offered it with a beefier, 6-spoke flywheel instead of the 5 spoke.
