A “Very Well Done” website! Never run across a stirling engine site that had such, “to the point” information and suggestions on their design. I also was able to “finally” find a copy of NASA’s Stirling Engine Design Manual #1.
Again my thanks for the time, the effort, and the sharing.

For years I was employed in manufacturing engineering in an industry which used many air operated diaphragm pumps. Which is basically what you are attempting to do.
I would suggest that you go to U-Tube and enter Wilden introduces full flow PTFE diaphragms. You will note how increasing air pressure (ie. heated air volume) is converted to a linear action. It then becomes only one step away to create rotation.
Have fun.

So what’s next? A beta configuration engine? Would that not reduce the dead space dramatically? (ie. having both pistons close together?) … I’ve seen some people on youtube make a piston out of steel wool, hence behaving both as a displacer and a regenerator – looked like a good idea, but not sure how effective it would have been. I’m quite interested in beta confirations and linear generator stirlings, although eventually when I get up enough skill looking towards a free piston design (super complex).

No it wasn’t a joke, and I think I explained my design as best I could.

Hi,
Just to let you know. I watched your vidio when you turned the engine by hand. It seemed to have some compresion like a petrol engine. Well there is something wrong because all the sterling engines I have seen or built do not have compression like yours. Look at the books again it is a smooth, none compressive cycle and I can not see how you pressurized your engine with 2 recycled food tins for cylinders? Maybe you were cracking a joke?? I hope you get fun from your work. Seasons greetings.
