Recently I became intrigued by a patent design sketch shown in a book about model Stirling engines, and ended up building a model. A 45 hp double displacer engine built in 1843 to power the machinery of the Dundee Foundry, in the UK. The original engine ran for four years before failing due to poor materials of that day that could not withstand the intense heat.There was not much to go on in the sketch, but that provides a lot of liberty to the builder. It was necessary to modify a couple things to make a working engine, but I tried to maintain a resemblance to the sketch. I hope you like it.
