Starting from the first day of our manufacturing engineering class, we were given engineering drawings of a Stirling engine design and its parts. As we learned how to use the lathe, the mill, the press brake, and other general tools, I machined each individual component to the appropriate tolerances.
In addition to machining, we sand casted the flywheel with aluminum. The sprue was cut off using a band saw and I turned it down to size afterwards.
Finally, the whole engine was assembled using machine screws, tubing, teflon tape, rods, a bearing, and a test tube. After tuning the engine slightly, it was tested using an alcohol burner and was able to run smoothly and continuously for at least one minute, the required runtime.
