Harmonique

[Richard SimpsonParticipant @richardsimpson88330]

I though some of you gents and ladies might find this interesting.  I came across it on Ebay around 20 years ago and couldn’t help buying it.  After a lot of digging around I eventually discovered that it had been made from a set of plans and six instructional articles in Model Engineering Magazine in the early 60s.  I contacted the magazine and was staggered to be able to buy original copies of the six magazines that contained the articles.

The engine is called the Harmonique and consists basically of two pairs of cylinders at right angles to each other with each pair connected and driving the crankshaft via a scotch yoke.  Its one of those sort of engines that you can’t help but run very slowly on compressed air occasionally just to enjoy watching it turn over.

I wasn’t keen on the base but didn’t want to disturb anything by remounting it, so left everything exactly as the original builder made it.  From what I can see it has been made exactly according to the drawings.

Richard, a very interesting model. Can you tell me the magazine volume number, year and / or issue numbers.

Thanks Alan.

Now your asking Alan.  I was just thinking as I wrote the paragraph that I’ve no idea where I put the magazines!  I will have a dig around for you tomorrow and hopefully manage to find them.

As for running, I should be able to sort that out.

There you go, thank you Jason.

Thanks guys. I have an exstensive library of ME and EIM and if I have those identifyed by Jason my next project will be building Harmonique

OK guys, today I gave the Harmonique a bit of a run after a clean up and an oiling and took a couple of videos for you.

Hope you enjoy:

Fascinating and very unusual,thanks for showing it to us.

[Richard SimpsonParticipant @richardsimpson88330]

You’re welcome Frank, glad you enjoyed it.  Sometimes I just connect it up and give it a run just to enjoy watching the engine running.
