Single Cylinder Air Engine, Experimental

A few months ago (June, 2017) I posted a video on my YouTube channel (https://www.youtube.com/user/popzct0214/videos) of Single Cylinder Air Engine, Experimental. After experiencing more than a few propeller strikes on my fingers, I put in on the shelf and decided not to publish it. Since then, I've had a few requests for the STL files, so here they are. Remember, this engine is experimental and when spinning the 10" propeller is potentially hazardous, so be prepared for precision filing,
