Do you have some details about your engine? Maybe a build log? I'm sure we all would like to see more...

Once I move beyond simple machining projects, I am going to attempt a stirling engine for my first real engine project :)

Very nice!

Brendon, I suggest you try something simple like a wobbler first. Then slowly work up to a Stirling engine which has a few more challenges ;)

Post by: Ian S C on October 19, 2016, 03:17:45 PM: My first engine was a Stirling Engine. I read a bit about them in "Model Engineer",in 1990 I then designed and built a
V type GAMMA motor that worked, parts of it are still working as a small Ringbom motor that I built about 15 years ago.

Title: Re: my first stirling engine running :)
Post by: Perry on October 19, 2016, 10:30:13 PM: Thank you Roger, I'm pleased with it, I was surprised to get it running immediately during first try.
Aluminum power piston seized very quickly but is replaced now with cast iron which works fine.

Next step will be static balancing.

Post by: Ian S C on October 20, 2016, 02:11:27 AM: Perry, with a motor built with the care that your one has been, I would be surprised if it didn't work straight off, only my first few were difficult to start, but once running were ok.

Title: Re: my first stirling engine running :)
Post by: Perry on March 18, 2017, 11:21:33 PM: Pegasus is a neat kit from Artoy.
I modified it so it can be driven by my engine or by a brass crank.
total reduction is cca 1:14
Original wooden crankshaft was fine for what it was but not suitablele for my stirling as there was too much friction.

So it is a semi metal conversion now, running on 2 ballbearings with brass excenter driving the horse.
+ I attached it to a larger baseplate

is is relaxing to watch it running just from the heat of small tea candle.

I know what I'll do Perry. When I get my P & W Hit and Miss engine finished and running, I'll hook it up to a Pegasus like yours. Only mine will look like its galloping! :naughty:

Hello Gas_mantle no other plans than standard Moriya fan were used, design details are my ideas + it is still not fully finished yet.

Post by: b.lindsey on June 24, 2017, 11:18:40 PM: Very nice Perry. That would make a fine display at a model engineering show as well!!

Bill
Title: Re: my first stirling engine running :)
Post by: Perry on June 25, 2017, 08:00:20 AM: Thank you gentlemen for comments, indeed I was inspired by various displays at Echtdampfhallentreffen in Germany.

I have few more ideas for accessories, such as :
Dynamo, praxinoscope, influence machine and an old style 78rpm gramophone would be very cool, if I can get enough power to drive it.

Japan toy maker Gakken made a nice kit, unfortunately it seems to be sold out now.
So I keep on searching for one..

Some other ideas for more interesting accessories?
Title: Re: my first stirling engine running :)
Post by: Perry on July 09, 2017, 12:45:44 PM: Marble race :) must ad more balls to eliminate gaps in "flow"

Post by: Perry on August 01, 2017, 11:20:52 PM: STIRLING powered gramophone :)
Pushing limits of little stirling further. This is first test with gakeen gramophone. Ultimate goal is to find enough power to play 10" 78rpm records with steel needle.

Post by: b.lindsey on August 02, 2017, 12:48:57 AM: That little stirling is a workaholic Perry. Fun to see all you have it doing though.

Title: Re: my first stirling engine running :)
Post by: Perry on August 02, 2017, 10:24:58 AM: Thanks Bill ! It is my first stirling and I can say it keeps on surprising me how well it performs.

Post by: Perry on September 28, 2017, 11:01:10 PM: New experiment came as a result of instant idea.. What about to hook my very first compressed air engine and to run it in reverse to compress air?
It works :)

I'm surprised the hot air engine has enough power to blow up the balloon.

Title: Re: my first stirling engine running :)
Post by: Ian S C on September 29, 2017, 03:51:10 AM: That's really neat, must try it. Ihave used one motor to drive another to try the effect of refrigeration, managed to drop the temperature from +20*C to -20*C in 20 miniuts, I thought that wasn't too bad. For a compressor I might have to build something.

Post by: Zephyrin on September 29, 2017, 07:41:18 PM: wow, all these animations are superb. Your engine is really powerful, congratulations...nice to return to the whole thread, and lot of ideas for animating a stand in a show !
the Pegasus is lovely, automata look to match perfectly with Stirling engine.
could you give us some details on the electrical generator ?
Title: Re: my first stirling engine running :)
Post by: Perry on September 30, 2017, 10:59:57 PM: Thank you guys, yes I was surprised too to get this performance out of it. Ian, the cooling experiment is something I'd like to try too. My plan is to power my stirling with my Webster IC.
The dynamo is a Sanko electric motor from old audiotape player. When time permits, I'll machine proper stand/housing for it
