Guys, Today I assembled the engine and it worked!!! It was awesome!!!! I'm very happy and proud! Thanks to everyone who helped !!! Below the link to the video: https://youtu.be/7GYh--ukyug I tried with a can filled with kerosene, but the flame wasn't focused on the engine, so i used the torch. I mad...

Yes, it is. For the cold chamber.

Hi everyone!

I've been working a lot last weeks, machining the parts of the engine. This weekend I'll start to build the crankshaft, which will take me some time.
The heat exchanger is almost done. I hope to post here the pics of all components and the engine assembled on sunday.

Cheers!

Hello, This week i've looked the tube for the cylinder and the tube I used in design is not that easy to find, so I've changed the tube for OD=1" ID=23mm its wall thickness is 1.2mm. The new piston diameter is 23mm for the power piston and 21mm for the displacer. Beyond that, I've changed the s...

Thanks! I'm buying the material next week, and I will start the machining on april 11th.
As I finish the parts I'll post here the results and the first trials.
Thanks for all the tips!!!

Thanks Ian S C! I've not machined it yet, so I can change to make it a lit bit heavier. The other parts do you think it is right?
I'm a little bit concerned if it will work, because a friend of mine did a project of a stirling beta type and it didn't work.
Thanks!

New pics after the changes I've made.
See what you think about it.
Thanks.

I'm trying to figure out the dimensions of the flywheels. I'm thinking on use 2 flywheels made of Steel with 3" diameter and 3/8" thickness. How can I calculate if the inertia of the discs is enough comparing to the pistons inertia? Some information i forgot to give you : The cylinder will...

Hello everybody! I've read the last month a lot of things about the stirling engine, specifically the beta type. So, now i want to do my own project and need some help guys. I read a lot of topics here in this forum and found out a lot of good information, so i decided to start the design of my proj...
