[youtube]https://youtu.be/cYm-SpDLyZU[/youtube] Current attempt, piston 4 inch diameter, displacer 9 inch diameter, both are 3 inch stroke. Working on scotch yoke crank shaft. Gamma configuration, smaller version of this design: https://www.nmri.go.jp/eng/khirata/stirling/kiriki/yama1/300strct.html ...

If you build a gamma engine using standard dimensions with a 6" power piston, reasonably well built with the usual attention to friction and good sealing, The output should exceed 200W. Hi, I am fabricating a large gamma. What are the standard dimensions for a 6" power piston? I am new to...
