Large stirling engine

Post by spom » Sat Jul 13, 2019 3:53 pm

Hi, I'm based in the Cornwall, UK and would like to share my fairly recent build of a hot air engine. It is roughly based on the rider Ericson design with addition of rocker arm and linkages. It is mostly made of easily obtainable items like welded steel tube and an old propane cylinder with a small amount of machine work for the crank shaft

I was going to eventually install it into a buggy but never got around to it and it's stayed in the wood frame since.

I've got a few youtube video's of it in action:

Just looking at the second video, I don't know how long the wooden frame work will last, perhaps you should get to work with some RSJ and a welder. When running the best load I have found is something that will give a fairly constant load that brings the revs to about half the free running speed.

That's a great motor, good on you.
