Re: How to make a piston for a cylinder
Beeing sarcastic. Or just buy a lathe. Or move to carpentery style stirling engine from rubber bellows. Which was done and can mome some power.

Re: Engine design sanity-check
Ok. But for un pressurised you need some 1000-2000 cc to power a boat.

Re: Engine design sanity-check
Hello. Will it be atmospheric or pressurised ? For 100 cc at 3-5 bar you would in 100-200 watts of power if you heater and cooler is right.

Re: aluminum piston and or cylinder
Technical capabilities - how big and good lathe do you have. Ie - i cant make good cast iron finishi, i have to give it for honing/polish. But alu is ok.
Cup seal or rings - cup seal is so much easier to make. But it is limited for 3-5 bar difference max. And wotks as one way valve too.

Ok. Which technical capabilities do you have ? I turn them from stock, or cut disc in washer form from thin sheet. https://www.google.com/url?q=https://core.ac.uk/download/pdf/35462647.pdf&sa=U&ved=2ahUKEwjs4vuUx672AhWWyosKHRtwAd0QFnoECAkQAg&usg=AOvVaw3PjWRGm_pF3GtG4BFvUh7f Page 124 will...

Re: High temperature displacer
Just do it in metal. Like from old candy box. Or just two pieces of 0.1mm ss foil with rolled sides and some tack welding.

Re: SWEPT VOLUME - SIZE OF AN ENGINE
Its all depends on configuration. 90 degree alpha with equal bore and stroke per cylinder swept volume is equal to 1.41 x single cylinder swept volume. For beta/gamma - equal to power cylinder. But phase angle is not equal to fisplacer and power piston angle differencies. Add different swept volumes...

Re: Alpha Configuration Advice
I think that "maritime" is another name for an engine with a cross-head mechanism in place of trunk piston. https://en.wikipedia.org/wiki/Crosshead Which is plus and minus for stirling engine. Where all goes to small details. And you could fold you mechanism, and have a cross-head in the b...
