Re: First Sterling Finally Running

So here is my ALPHA motor, similar power out put to the Beta above, but about twenty years newer. The steel cylinder head has been replaced with an aluminium one, and the water jackets are gone(they never were used, it would go all day without over heating), these are replaced with aluminium fins. I...

Stuart, that's the some conclusion that I came to.

Re: Davis Charlton burner housing

On the PM web site the motors are called "Solar Engines" although to run this type with solar heat could take soe ingenuity, but I think where the name came from was the motor with a parabolic reflector, sitting on a tripod, a friend has one he got from the USA many years ago after seing a...

Re: Davis Charlton burner housing

PM research seem to have quite a few Stirling Engines of similar design, the others having Pyrex glass hot caps, and glass power cylinder. The PM motor measures 7" x 4 1/4", and I think the flywheel diameter i2 3/4", so the size seems the same, I wonder if the cylinder bore is the sam...

Re: First Sterling Finally Running

With a generator on the motor, it I possible to use a small electric fan from a computer, but these are generally 12V. one of my motors has one fitted to it's radiator.

Re: First Sterling Finally Running

You could try a spirit burner with a small wick.
It's difficult with this type of motor lay out, but a belt driven fan can work well.

Re: Davis Charlton burner housing

You should be able to cut up a tin can to make a cover. First get some cardboard, and make a pattern with that, and when you get that as near right as you can get it, copy it in a bit if the tin can. A lot of tins these days are corrugated which doesn't always look too good. Watch out for sharp edge...

Re: Davis Charlton burner housing

Hi Stuart, could you put up a photo of your motor, I've made covers for burners on my motors, but none of them look like a chicken coop.

Here's another type that is simple to make, and if you have a log burner it will sit on that and distribute the heat around the room

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

Hello Frank, we are still here, but things are a little quiet. I machine the parts for my Stirling Engines, The ones I have built range from a power cylinder bore of 10 mm to about 55 mm. Here is the smallest one, as usual (for me) it's my own design. The over all length is 170 mm, and the flywheel ...

Another thing is getting the diaphragm right, not too tight, not too loose.

Re: I have tried multiple times and can not build a soda can sterling engine :-(

To get the dimensions right, all you need is a rule, it doesn't matter if it is in inches or mm, but that is just following the book and video easy enough. more important is getting the motor to turn with minimum friction, most important. Next, to have minimum air leaks, the trickiest one will be wh...

Re: Tesla's "Ambient Heat Engine" Experiment

Tom I have run my LTD motor on ice, the ambient temperature was 20*C, so there was a 20* (a little less) temperature differential. The but is the amount of energy required to make the ice.

Re: Flame eater V2

That's a very good looking little motor, it runs very well, thanks for showing it to us.
Is the glass tube across the cylinder heads the fuel tank incorperating the burners, a neat idea.
