Thanks Ian. A real nice website. They must have spent years honing their craft.

I once remember seeing a website that sold a huge selection of stirling engines in the links section of this forum. I think it was a german website. Does anyone know the site i mean?
Thanks

Hello Ian. What is the difference between a v type gamma and a v type alpha?
Wellington

I need a super simple way to control the rpm on a horizontal alpha engine so as to not overcharge a battery. I've seen centrifugal governors on steam engines but these require machine shop tooling to make. Is there a super simple way to control rpm mechanically without machine shop tooling? Thanks W...

Well with alpha, both pistons and cylinders can be identical on same crank pin 90 apart. Displacer is misnomer here. Either hot or cold piston. ]# Its a horizontal engine that looks like a gamma so no right angle to put on same pin. Im trying to copy this engine: https://www.youtube.com/watch?v=w5R...

Im currerntly building my first engine. Its a horizontal unpresurised mini alpha engine. How should i ofsett the crankshaft? does the displacer piston go 90 degrees ahead of the power piston? Thanks
Wellington.

thankyou Ian

If you drive a gamma engine in the direction of normal rotation, with the displacer leading by 90 degrees...........

Thanks Wayne

After I built my Ross Yoke ALPHA motor, I joined it via a belt drive the one of my other motors, and over about 20 minutes I let them run. The ambient temperature at the time was +20*C, and at the end of the test, the end of the hot cap on the ALPHA motor was -20*C, a drop of 40*C, no doubt that if...

Can anyone explain the basics or provide a link on how to make a stirling refrigerator.
Thanks

Wellington, yes use light weight steel, or stainless steel. Weight just causes extra friction.................... [img] DSC01133%20(800x600).jpg [/img] Yep. I imagine the friction would go up. On another note: I remember once seeing a german website which sold lots of different stirling engines but...

A displacer that is extra light weight............

Thank Trevor. will steer clear of aluminium displacer.

Hello all. i want to build a stirling that produces good horsepower. Should i use a light weight displacer or a heavy displacer?
Thanks All. Regards
Wellington.

It would have no comparison with an engine heated by a meths burner, the water jacket would have a maximum temperature of 100*C .......... That's good to know. I was starting to think i would need lots of pricey tubing. I've been looking at the twin syringe engines. They appeal to me because they h...

Hello Has anyone any advice to offer regarding the idea of putting a water jacket around a stirlings hot end to heat the hot end with heated water from meth flame?. Ive seen stirlings running in cups of warm water before and am curious to know how performance will compare to heating the hot end dir...
