I have a full cnc machine shop so I'm well equipped to make good quality parts. My hope is to come up with a commercially viable generator for cabins and for camping etc.

Thanks for the info guys. So Ralf. In one rotation the pressure change is how much psi? I'm not quite understanding what you mean. I'm trying to work out the force applied to the piston. I'm going to use a two 4 inch diameter pistons. I also had another thought. Has anyone tried putting a bit of wat...

Is it better to go single cyl or twin?

Yes. I'm thinking of gearing up the flywheel so it carries the slow moving crank past TDC and keeps it going

Something like this

Ok. I'm thinking of building a Stirling that runs fairly slow soit has more time to heat and cool and uses the resulting torque to do work rather than high speed but low HP

Has anyone tried using an air cylinder for a power piston?

Hi everyone. I'm wondering if anyone knows what the pressure change is inside a Stirling engine while it is running?

I love those old engines. This will be my first hot air engine. Before that I built a "Masie" live steam engine years ago.

I thought about the diaphragm but I want the cold cylinder walls to contact the air as it reaches BDC

Thanks! BTW, has anyone tried using a rolling diaphragm seal?

I'm going with two 4 inch diameter pistons.

So! Best seal for a stirling engine power piston?

Hi everyone. I'm 51 this year and got my first introduction to stirling engines back in 1980 when I was a school kid. I was more interested in model steam engines back then and my good friend and mentor Les Warnett helped me learn the design and machining process. These days I have a very successful...
