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.

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?

Re: Sterling Engine not running

I think it's complaining about being locked in a cage, go on it's not a Lion. Seriously though I think you might need to take out the power piston and clean the oil off of it, and wipe out the inside of the cylinder. Did you actually find where the unusual noise was coming from, was it the bearings,...

Re: Problem Rider Ericsson model

I would have thought that the valve opened when the internal pressure dropped below the atmospheric air pressure, I could be wrong, but I'm just going by a friend's vintage Heinreci motor. You can seethe snifter valve on the left , just above the fire box, a small brass fitting below the water pipe....

Re: Need advice buying my first sterling engine

Generally I would say that a Stirling Engine power grid is a different technology to a diesel based one, With a diesel power unit you start up and use the power as required, then shut down. With a Stirling based power supply, you would run it full time and charge a battery bank, this bank can be rec...
