Jeroen Jonkman built this Gamma type Stirling engine for his father’s 60th birthday. He also drew a nice set of plans for it and is very generously sharing them. You can download them here from MachinistBlog (PDF) or from HMEM if you’re registered there and logged in. I asked, but Jeroen didn’t tell me much about himself. But I can tell from the videos he uploaded to his YouTube channel that he’s a skilled machinist and prolific builder of model steam and Stirling engines, many of which are of his own design. Jeroen is also Dutch and I find it interesting that two other Dutchmen, Jan Ridders and Jos De Vink, have built some of the world’s most beautiful and interesting model Stirling engines. Jeroen has not produced as many engines as those two but I wouldn’t be surprised if he does someday.

Good afternoon,
need help with engine Striling 60.
Please tell me where can I can get?
Thank you.

What’s the problem? Maybe we can help. Otherwise, you’ll have to register at HMEM (see link above) and ask for assistance there.

Good afternoon rleete
Thank you very much for responding.
I would like to provide me an E-mail to send some pictures and ask what are the critical points to consider to work properly.
Both the main piston and the power piston are sealed, that is, without any leakage. Not if it is correct to give both fit and if needed give out the air by one of the pistons.
Thank you very much for the help.
I feel bad after so much work not work.

The main things to consider for a Stirling engine are fit of the piston (smooth sliding, with no tight spots) and eliminating friction as much as possible. The power piston must be airtight, but the displacer should have clearance all around. Friction is the real showstopper. If a joint is binding, even slightly, it can prevent the engine running as they have very little power.
Also, my Stirling engine needs to warm up for several minutes before it will run. Put the heat source on it and let it sit for a minute or two before trying to get it to run. Finally, an alcohol flame will burn hotter, and may make it easier to run than using a candle.

Beautiful simplicity!

Good morning. I have downloaded the drawings of J. Jonkman’s Sterling ’60′ engine – superb clarity, nothing too difficult to machine. But I cannot find the connecting rods, displacer to crank, nor Tumbler to crank. Do I need to measure these empirically when the time comes to make them, or can I scale them off the drawing on Sheet 3/8 ?
Many thanks.

Hello, good afternoon,
I’m wondering about cylinder’s minimum temprature for the mechanism’s start to circle. I’m waiting for reply. Thanks.
Sincerely, Aziz the engineer.

Not sure of temperature, but it has to be warmed up. Mine won’t start until the flame has been on for about 30 seconds.
Even then, it has to be manually started by spinning the flywheel. A quick flick with a finger usually gets it going. As it gets hotter, it runs faster.
Hope this helps.
