The Engine that started it all…  This Fleishman steam engine was give to me and my brother for Christmas when I was 6 years old.

 

sDSC01505

A Stewart Turner 10V I machined from castings. I use a lexan steam chest cover so the valve can be seen in operation.

 

STiny Boiler

A tiny boiler and steam engine with 3/16” bore and stroke.

 

sDSC02159

These are “Mystery” engines of my own design. There are no valves. A closed volume of air is contained inside. Placing a heat source at the end of the steel wool located inside the test tube is all it takes to power the engine. Some say this is a thermo-acoustic engine, but I don’t believe it. The engine on top was used in development to determine the proper stroke for the piston.

 

sDSCN0720

An offset crank engine I call the “Leaky”. The piston is only about 0.025” long. Near the top of the stroke, it seals closely with the cylinder wall. The piston tilts to allow the incoming air to leak bye as the piston travels back in. This will do several thousand RPM.
