I had posted a while back in the plans section about a remake of IronHorse's caloric engine. I like Stirlings anyway; but I thought that his was exceptional, and obviously others did as well.
I decided to model the engine with a few changes that I thought may make a difference in how it runs. Sort of an experiment anyway.
Here's a photo of the parts I have gotten a start on.
The cylinder I finned because in one of IronHorse's posts, he mentioned getting a lot of heat on the cold end of the displacer cylinder. Just one of my attempts to reduce the heat.
I also decided to use a two-piece displacer cylinder joined by a threaded coupling, with the lid between the two halves.
I'm not sure this is going to work out, I might have a problem with leakage here. Anyway, the assembled parts so far look like this....
The individual parts are not at their final finish because I am fitting things together and making "edits" as I go. I know better than to start to make parts before the design is done; but sometimes I have an easier time deciding if I like the looks of something if I can actually pick it up and look at it, sooo....
Anyway, comments, good or bad, are welcome.
