I'm wanting to design and build my own a gamma type Stirling engine.
Could anyone tell me what size the diplacer cylinder needsto be and
the power cylinder.

I have made just one working Stirling and used about a 20 to 1 ratio (displacer to power cylinder volume) It was largely a guess and my goal was LTD. If your wanting more power, rpm and don't mind adding more heat than a candle then the ratio is about 1.5 to 1 with the dislpacer taking up two thirds of the volume...if memory and what I've read is correct. My "store bought" Solar 1 looks to have about that ratio and does take a lot of heat to run. Hope that helps.
