Is there a formula I should use.

I work full time and run a small business. I don't have a whole lot of spare time. I'm not an engineer, nor do I possess a machine shop. However, I am good with my hands. I heat with a large indoor woodstove. I'd like to see a sterling engine run fan sitting on it. Maybe 2.
Is there a good tutorial thread here for something like that?
I'm also looking for information about what size things should be in relation to one another. Primary cylinder, displacer, power piston... if I found a couple of cans I'd like to work with, what size should everything else be? Is there a formula I should use?

FYI: When I click on the "free plans" link I get a prompt that says "page not available".

You have a wonderful sense of humor. I didn't get any answers then either. Guess this forum isn't worth much.

Also the Schmidt analysis can be used:

Or the Beale equation and number:

I would stick with o 0.11 or even 0.1 until you get your own calculations of the number for your style of engines. It is only a starting point.

The Stirling Engine Design manual is large but well worth it. It is a free download PDF:

If you help getting started just post here any questions. Please.
