Simple Stirling Engines built from the plans

Occasionally I hear from others who have built the simple Stirling engine from my plans. Most people end up making some kind of modifications to the plans. That’s fine with me, in fact I enjoy seeing how other people solve a problem. The only area where experimentation could be risky (in terms of ending up […]

Simple Stirling 1 performance with and without regenerator

I’ve tried a variety of regenerators on the Simple Stirling 1 engine and the one shown in the photo is simple to make and performs as well as or better than all of the other ones I’ve tried. The test results on the engine with the original displacer and with the modified displacer containing the […]

Simple Stirling 1 Engine Materials List

The bill of material for the Simple Stirling 1 Engine is now available. Together with the 3D model, the part drawings, and assembly drawings, you now should have sufficient documentation for building the engine. I believe I’ve covered every single part including nuts, machine screws, and washers.

Simple Stirling 1 Plans and Assembly drawings

I have added color to the 3D CAD model. You can see it compared above with the physical prototype. There are a few difference between the two—the four support rods on the prototype are about 1.5 inches longer than on the plans. You might also notice I have the crankshaft set 180° from the CAD […]

The Simple Stirling 1 Plans are done !

The plans all drawn up. You can see a 3D pdf model that gives you the ability to look at every single part from any angle. If you haven’t used this Adobe 3D view make sure to try both mouse buttons and the mouse wheel for navigating the drawing. There is a directory tree that […]
