Re: Heinrich Motor hot air engine

Flywheels are needed to supply energy for the complete rotation especially under load. For no load, I doubt the engine requires both flywheels. I recommend just trying to get it running as is. Oil everything with marvel mystery oil and hook up the higher port to a garden hose and heat it up and see ...

Re: Heinrich Motor hot air engine

Wilson, have you tried running it? You'll want to use a light oil - sewing machine oil. Typically those engines have two flywheels. Hopefully, yours doesn't require it. From what I've read a Bunsen burner should be enough to make it go. To get more power try ice water for the coolant. That could hel...

Re: Heinrich Motor hot air engine

Ian, of course I want a full size vintage hor air engine!
I like to go to old tractor and steam shows.
I have yet to see a full size water pumping hot air engine in the last 30 years. Very rare in these parts.
I do remember my father showing me one at a show when I was young. It's a vague memory.

Stirling powered toy car

I got a Meccano kit and made a toy Stirling car.
I was going to use gear reduction but I read gears rob power with friction. The rubber band drive has a nice feature as acting like a clutch as they stretch and spring back.

Re: What a difference a flue makes! +75%

Ian, from your alpha how many watts of electrical power are you able to generate?
What's the bore and stroke?
And it looks like you built it to be pressurized. How much does that increase the power by which pressure?

Re: What a difference a flue makes! +75%

A guy is selling these things on eBay. It was a long wait to convince my wife. But I finally got the Japanese Ross linkage engine. I'm very impressed with the power. It produces enough electricity to run a 6 volt motor with 100 milliamps on 90 pct alcohol. Probably the most powerful of my stirling e...

Very clever Siemens style 8 cylinder engine

The cleverness of a Siemens engine is that uses the same bore twice which is more efficient. In https://www.youtube.com/watch?v=XsD8aI6nPV0 instead of a wobble plate, he uses 8 gears arranged in an octagon. Jump to 4:48 to see gears. How does this compare to a wobble plate design? A four cylinder co...

Re: Thermo like propane engine

Looks like a Duplex brand beta-type Stirling

Perhaps a Chinese brand? I wonder if they were made in large quantities?

Thermo like propane engine

I saw this model engine on eBay listed for only 20 usd from China.
Looks propane powered and similar to the Thermo antique engines. I didn't buy as it seemed too good to be true. Anyone know about the engine?

Re: New to Stirling Engines...where to start?!

There are many types of Stirling engines. Alpha, beta, gamma etc
Lots to read, but fun to learn

Re: First Sterling Finally Running

Have the model be vertical with hot side down. Less friction.

Re: MY FINISHED MODEL Robert Stirling's Famous Hot Ait Engine

A YouTube video available? Looks awesome by the way.
As a test, maybe put a bead of playdough in the groove? I wonder if it would run faster or slower...

I didn't realize solder sticks to stainless...

Re: First Sterling Finally Running

Of my Stirlings, the one that can run and run is an alpha in a V layout. This keeps the cold cold and the hot hot.

Gamma layout is a poor one. Alpha came later and let's face it. It is more advanced. Why monkey with poor designs?

Re: Power producing low delta T state of the art?

What was so revolutionary about your Stirling engine? You had a year to patent that but that timeframe expired long ago.
So you might as well share the idea.
Post a picture, etc.
