Description:

Originally, this was supposed to become a flame eater engine which I had found on the Roy Ricewebsite. It was not the timing mechanism connected to the flywheel that proved troublesome, but the lack of graphite to manufacture the piston -- my cast iron piston kept rusting... And I had no intent of disassembling the engine for maintenance after each run. The end of the flame eater came when I ended up dismantling it completely, reusing the cylinder (the first one I had completely built by myself!) for another Stirling model, a larger version of Christer Carlson's engine. The idea of building a flame eater is still in my mind, especially since I located a vendor for graphite
