Re: My stirling engine school project

Hi User1, If you are building an ALPHA motor, it"s worth down loading Andy Ross's book "Making Stirling Engines", it's a free download, if you print it out it's 68 pages. No, steel wool won't work, you must have 2 well fitting pistons in proper cylinders, one the hot cylinder has an extension, the h...

Re: Burnt pancake displacer (carbon foam)

Thanks for that Bumkin, as a first thought it could be used to line the furnace around the hot cap of a Stirling Engine. Also the blackened stuff (what ever you want to call it) could be wrapped round the cool end to dissipate heat. Something to think about.

Re: "Hi...We are new here!" First posts here (or anywhere is OK)

Welcome Voxelman, you'll find all sorts here. For home and water heating, go geothermal. For electridity I am coming to the conclusion that the best way I can see is if a group (city block, sub division, small town) get together and provide their own power, and at the same time their own cell and in...

Re: Hello from a new member

When ever you have a few minutes to spare it's worth going right to the start and read a thread or two, and slowly work your way through, you'll find some good ideas, and some that are "well a bit odd", but all learning.

Have you had a look at Boydhouse's free plans in the top section of the index, hes the expert in tin can Stirling Engines.

Re: Need a 50 watt power output providing stirling engine

If you have a machine shop, and know what you are doing, 50 Watts is not impossible to build your self. In this country I would expect to spend about $NZ 500 for materials to build such a motor, that's why my bigger motors have cost no more than $NZ 40, and produce 5 Watts, a lot of the stuff I use ...

Re: Small Beta type stirling engine not running

I think I can see why the motor wont work, you have a large clearance around the displacer rod, you need absolute minimum without binding/friction.

Re: Designing a Beta Stirling Engine (Please help)

Sarahwad, I imagine that you propose to build a pressurized motor. I would suggest that you down load Andy Ross's book "Making Stirling Engines" (it's free). I have run one of my larger unpressurized BETA motors, 1 3/4" bore using a large Freznel lens 24" x 18". It was summer time, and I am at about...

Re: Design and Manufacture of Beta Stirling

If you don't have a lathe the cooling fins can be made up from aluminium discs, all with the same size hole then alternate large and small outside diameter. One of my motors has fins like that, with three thin, long bolts through all the fins and spacers. The aluminium came from a surplus pot from t...

Re: Design and Manufacture of Beta Stirling

I agree, but what are the ? 4 black rings around the middle of the top half of the displacer cylinders? These commercially produced motors seem to be more ornamental than productive power producing machines. For cooling, some aluminium bar bored through for a light fit over the displacer cylinders, ...

Re: Beta engine measurements

Jonathan, your power piston is going to be 18 mm in diameter, if for example you made the power stroke10 mm, then the displacer would have a stroke of 15 mm, just make the displacer stroke 1.5 x the power stroke. You either need two cranks at 90* on the crankshaft, or it can be done with a single cr...

Re: Sterling Engine not running

Have you tried running your motor with the power piston, and it's cylinder wiped clean of all oil?
