This is my home made hot air engine running on wood the power cylinder piston and crankshaft are made from a 2hp briggs and stratton. The spark plug hole was drilled out and fitted with a 1" pipe fitting and the displacer cylinder is an old air tank. It still needs work as the cooling tube is not cooling it fast enough soon i'll make and fit a water jacket to it as that will make it cool more effectivly. The idea came from the website www.boydhouse.com/stirling/ Theres plans for building one from tin cans i just scaled mine up a bit
