I disagree with your findings about alum and your idea about polyacetal. I also happen to know he is building a walking beam engine. :grin: The best piston material is graphite. Harder to get. Hard to machine in a garage without a lathe. Very light weight. Self oiling. Very minimal expansion . Will ...

Re: Help with aluminum piston
The piston length.........Too short and it will try to turn in the cylinder.......Too long and you are wasting energy moving it. On a 1"long piston I would pick around 3/4" long plus or minus. Drilling holes in it to make more of a vacuum?...... Sorry I am not sure of the question here. we...

A Stirling engine is a temperature differential engine. It runs on the difference in the two temperatures. The greater the difference between the two the more potential it has. But you can also lower the temperature on the hot side if the cold side also goes down in temp. Or visa versa. Just keep th...

Horizontal tin can engine.......running?
In the final phases of this engine. Thought you guys would like a peek before it is done.

Initial runs show some more work to be done. 3 or 4 cycles and it stops. Not from friction, but lack of power.

Air Cooled Hot Air Engine Plans (tin can engine kind of)
I ran across these plans to build an air cooled hot air engine on ebay. It was an old 1961 Pop Sci magazine article. I purchased them. About three weeks later I ran across an air cooled hot air engine for sale on the internet by an antique dealer. Well I was surprised when I realized it was the same...

That faire sounds like fun!
I'm am in the Bay Area. In Concord.
I'm going to try to get there! Looking forward to seeing your engine run!
Keep going!

Yes they do run. I'd say most of them run the first time. Maybe 20% have some sort of problem the first time out. :sad: If it is the walking beam engine, most people email me and get help. But we get them running after a few runs. I wouldn't put up the webpage if the engine didn't run. As I don't ma...
