Large Water Cooled Stirling Engine

Another ebay find, this is a rather unusual water cooled stirling engine.

[@Lechoslowianin]

Very nice and unique engine. It was a good purchase

[@txlabmansteamtoysmore4980]

Such a neat engine. The maker was very talented. 🤠

[@markmatthews8429]

What a nice engine that is, looks well made. Could sit looking at that running for ages.

[@RetroSteamTech]

Yes, it does have a nice motion. I liked the unusual linkage and motion of the Robinson engine that I did a video on about a month ago.

great find that , well done for winning, runs really well

[@andrewdolinskiatcarpathian]

How very sweet. Very nice engine. Great runner. You did very well. Thank you for sharing. Andrew 👏👏👍😀

[@RetroSteamTech]

Thanks Andrew. Yes it is rather unusual. Cheers, Alan.

Thats really a nice engine!

I actually have one started with that similar design other than the water cooling part of it. I had set it aside for other engine projects but after watching this very cool engine running it has spurred a new interest in finishing the engine I have half way done on my bench! That was a great score for your collection! In fact my flywheel is actually steel with a brass ring around it.

[@RetroSteamTech]

Thank you. Very much like to see a video of your engine when it's finished.

Hi Alan Another one brought back to life, great engine, i may make one in the future. When i've time on my hands. Thanks for sharing Take Care Kev

[@RetroSteamTech]

Hi Kev. Thank you, I thought it was a bit different to the run of the mill stirlings that you see. Cheers, Alan.

Great little engine, unusual design. It would look good polished up, I thought it might be missing a base as it's unsteady on those legs.

[@RetroSteamTech]

Yes the copper would polish up nicely and a base would definitely be an improvement.

Hello Alan, It is a very cool engine... Could you put some sort of extension pipe to the gas tank to allow of easy filling... See you on the next one. Take care. Paul,,

[@RetroSteamTech]

Hi Paul. Thanks. Yes an extension to the filler would be ideal, might well look into that. Cheers, Alan.

[@MattysWorkshop]

Gday Alan, this is an interesting engine, I’d really like Rob for Xynudu build something similar, all the engines he builds are great and run well, thanks for sharing mate, cheers

[@RetroSteamTech]

Hi Matty. Well if anyone can build one of these it will be Rob 👍👍🙂 I thought it was a bit different to your run of the mill stirling engines. Thanks for watching. Cheers, Alan.

[@CraigLYoung]

Thanks for sharing and Merry Christmas 🎅

[@RetroSteamTech]

Thanks Craig, Merry Christmas to you too 🎅

[@warrenhaines1717]

Very interesting little engine. Runs nicely 👌

[@kimber1958]

VERYCOOL

[@olivvapor4873]

Woaoww I just love it ! 😊👍🏻

[@Xynudu]

Nice Stirling Alan. I might try that configuration with a round water tank (easier to fabricate). How is the power piston sealed ? I'd be interested to have your best guess at the bore/ stroke/volume of both cylinders to work out the ratio they used. The legs on the bottom look like they were re-used from something else (hand rail ? ) as the cross holes seem a bit unnecessary. Cheers Rob

[@RetroSteamTech]

Hi Rob. I thought it was a bit unusual which is what attracted me to it. The power piston has a bore of 1.245" and a stroke of 1.34", odd dimensions. The stroke of the displacer is the same and the outside diameter of the displacer is 2.243", again strange dimensions. The power piston appears to be threaded into that flange which is then bolted to the brass plate. There is no evidence of any gaskets. I think you can see from the video that the top of the displacer cylinder overlaps the bottom of the power cylinder which must be how they are connected. You may be right about the legs, possibly hand rail stanchions. Cheers, Alan.

[@Xynudu]

@@RetroSteamTech Thanks for that info Alan. I haven't made a Stirling for quite a while and may try this pattern. I would scale it down a lot to the size I like working with. Interesting unit. Cheers Rob

[@strawberry-parfait3922]

You could try building a much quieter stirling engine on it instead that uses the water to cool down the cooler cylinder. And have a little BBQ grill or something on the hot cylinder 😸 Apparently its a popular niche hobby of old brits kzbin.info/www/bejne/bmPIgJ2gpJ5_hrs

[@RetroSteamTech]

Always good to stirling engines actually doing some work 🙂
