Very nice looking little engine.

Gil,
Not really like a Robinson which used a vertical displacer and horizontal power cylinder (reversed in your model and HOG engines. Robinson also didn't use walking beam linkages. Again, don't mean to be critical--it's a very nice little engine. It seems ANY unique model engine design is going to be copied these days by either China or India.
Hi Brent, You are correct.... most any unique design will be copied and it isn't just the Chinese and Indians.
Here is a German built Stirling Cycle Beam Engine. Herman Bohm started designing and making Stirling Cycle Engines in 1990 which is 7 years before HOG began. I don't know just when he came up with his first beam engine but I think it was early on.

A beautiful little thingie that, and runs amazingly well for its size...
Very nice addition to Simone´s impressive miniature collection, congratulations !!!

Cute little engine.

This one looks well made Gil.
Congratulations to Mrs. Redryder on a fine addition to her miniature engine collection.
And thanks for posting the pictures and video.
Regards,
Charlie

What about Robinson? Made an L shaped Stirling Cycle Engine in 1816. Aren't most with the L configuration based in some form off an engine much earlier than the Hog (ca 1997?). I found it more troubling that India and some others were producing cheap poorly functioning exact copies of the HOG Motor.

I like the size and it runs well but wish they could come up with their own original designs. This is more or less a knockoff of the German "HOG" model stirling engine. Don't mean to be critical, just my opinion.
-
Certainly a very tiny Stirling engine which goes very well with Mrs RedRyder's other mini engines!.
It does run at a fair rate of knots too, the ball bearings probably help with that!

What a little Screamer!
I also am amazed it doesn't fly apart, but astounded that the thing can maintain that pace and operate using the Stirling cycle at with so little opportunity for the needed heat exchange on each cycle.
-
As promised....
Here is a video.
It's a lot of fun in a little package.
I am impressed merely by the fact that it doesn't fly apart at such high RPM.
Enjoy,
Gil

We learned that with a real short wick and less than 1/2 a bowl of fuel, it could be run without flare-up as it did in the beginning.
-
While it looks a little different from the catalog pictures, it is mostly the same.
It just has a more solid support and a flywheel with holes vs spokes.
I'll have a video up soon.

MrsRedRyder and I were looking at some offerings on the Banggood site and stumbled onto this miniature Stirling Cycle engine.

She thought she should have it for her collection of miniatures and I wholeheartedly agreed.
A few clicks and a few days later and here it is!
