Dave Gingery's
Two Cylinder Stirling Engine
Dave Gingery's letters tell most of the story:
"Here are a couple of sketches of the new hot-air engine project...
I've built a single cylinder engine of a similar design and it runs great.
Practically no sound or vibration at about 1200 rpm... It is a great training
project that should be appropriate for second and third year shop students...."
This is a free-style design with no practical application except as a demonstration engine. However, it is not a toy engine, and the builder will gain some valuable additions to his tooling as well as acquire new skills...
Aluminum castings are a major portion and the remainder is made of common water pipe, drill rod, brass rod and ordinary hardware, fittings and sheet metal. A small lathe fitted with faceplate, chucks and ordinary tooling will do the work. You will greatly expand your skill and you will end up with a mechanical marvel ..."
Dave stopped by one time and fired up his prototype engine. From the outside ends of the opposing cylinders the engine is 11 1/2" long. When he fired up the alcohol burners, the engine sat there on my desk and silently started spinning. It was really something to see.
This
is an external combustion engine but it does not use steam to carry the heat
energy into the cylinders. Instead, it uses hot air. The engine was perfected
by Rev. Robert Stirling in the early 1800's. John Ericsson, the Swedish-born
engineer contributed substantial improvements to the engine.
"I've killed a disgusting number of hours watching it run."
This is the usual full-tilt Dave Gingery manual with all necessary illustrations and step-by-step how-to that has made his name a famous one among machine shop enthusiasts. (Engines have been built without using castings.) You get history, theory, drawings, photos, the whole thing. Another Gingery book!. A "must have!" Order a copy today! 8-1/2 x-11 softcover 76 pages
