Cant find old website

[Wellington]

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

The German site that I know of would be that of Bohm Stirling Technic, they make a number of novelty Stirling Engines. I'v got the Type HB 7, a little horizontal GAMMA motor, not really a brilliant design as far as easy running, you have to take the piston out each time you run it , and clean the bore and the piston.

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

Quite the contrary. Boehm engines are junk imho. Make it run before you make something pretty.

This engine Japan is pretty and a superb runner.
Generates meaningful power.
Less expensive than Boehm as well.

I think the engine had a limited production run as the manufacturing company seems out of business.

One immediate problem is the power cylinder and piston. The cylinder is brass I think, unless it's anodized aluminium, the piston is a stainless steel cup shape, the open end of the cup goes into the cylinder, that part being dead space, the con rod connects to the bottom of the cup/piston. I think I may bore out the cylinder and put in a cast iron liner, then make a proper piston from cast iron, with the flat end going into the cylinder as it should. I will then see about putting fins on the cylinder for cooling.
cbstirling, the Ross Yoke motor in your link looks good, I'm sure it would produce more than .6 of a Watt. Don't know where the microphone was in the video, the motor makes quite a bit of noise.
