This engine is extremely interesting to watch, and runs at speeds up to 1500 RPM. This is a hard combination to beat. A Pyrex heat cap, replaceable Pyrex power cylinder, gyro-quality ball bearings, bronze flywheel, aluminum cooling fins, and sand cast aluminum frame are only a few of the outstanding features incorporated into this engine. The completed glassworks kit measures 7-1/2" X 4" X 3-1/2".Comes complete with 3 castings, bar stock, screws, hardware, assembly and detailed drawings. Machining and assembly required.
