Stirling Prototype

Small-scale Stirling prototype. It took maybe 6 or 8 hours to build, mostly from scraps. The only really tricky parts were the piston and the displacer shaft, both of which have to be air-tight.

A few more candles (or a larger one) and a smaller flywheel would probably get this guy really moving.

how did u make it could u tell me how

I didn't make it from any plans, if that's what you mean. But if you read up on stirlings, it's pretty simple to design your own with the scraps you have.

I found a rod and a tube at the hobby store that were a good fit. Same for the piston and cylinder, although that was two tubes that fit well together.

Nice work, you should try making the power piston stroke shorter to get more speed out of it.

Very well for a device made out of scraps, decent looks and it runs.

now to up the RPM?

Nice engine!How did you tigh the displacer shaft?
