I believe that article is from Scientific American . Looks fairly reasonable, but I suspect that it isn't much more than an oversized tin can engine. There is a book being advertised on http://www.AmericanSterling.com that describes a 5 horsepower engine built in Bangladesh out of scrap. I don't kno...

If all works well, you can determine the timing of the system by moving your heating element by hand and watching the response from the power piston. Cartech: I like the reverse flow idea for the passive solar engine! I would still want to avoid valves and such if possible, but at least you've found...

Tom, I think you may have blurred the purposes of the displacer and regenerator. While they can be physically the same component of the engine, they don't necessarily have to be. In fact, a regenerator is not necessary for a Stirling engine to produce power, it just improves its efficiency. Examinin...

The whole purpose of the displacer is to move the enclosed air from an external heat source to a heat sink. I think this is the genius of Stirling's design: there are no valves or complex passages. Keep in mind that you probably want to keep your displacer as light as possible, since moving it (in c...

JB weld holds up under low flame and super glue almost immediately burns up. Soldering the aluminum will probably be a more permanent solution, but it will require the appropriate solder and flux (it's one more reason I tend to stay away from aluminum in my construction... aluminum requires a specia...

Hi Tom, You have some neat ideas there! Here are a couple of random thoughts I have about what you have proposed: - You're basic notion of how a Stirling engine works is correct. Please note however that you sketch has the displacer and power pistons 180 degrees out of phase; they should be 90 degre...

I'm guessing that as long as the port doesn't impose a restriction to air movement (along the lines of a pin hole sized opening), it probably doesn't have much of an effect. It might be a cool experiment if you installed a spot for a restrictor plate in order to test different port sizes, but that m...

Hi Cat, My first thought would be to consider both your skills as a machinist and the tools you have at your disposal. A Stirling can definitely be built without a lathe, but you will be reducing the number of design options since you will need to use materials and components already available. As f...

Gamma Beam
Hi Everyone, Just dropped in to show off my newest engine. http://www.stirlingengine.com/file-storage/download/Stirling2-002.jpg?version_id=258 It's a gamma type beam engine. It stands 7.5 inches high with a 3 inch flywheel and about 2cc volume. My most recent test runs clock it at about 700 rpm wit...

(Stan) Comment: The pressures on the double acting piston will more than likely not be balanced throughout the cycle. This will result is less output than for two engines running in parallel and phased 180 deg apart. Well, I just started reading chapters of Rizzo's Volume One that I had passed up b...
