Scotty Hewitt is a former race car driver who turned to machining as a retirement hobby. He has built several contest winning compressed air race cars modeled after vintage dirt track racers. For this project, a miniature J.C. Tanner tugboat, he took plans for a small oscillating steam engine and scaled them down significantly. Mr. Hewitt then fitted the mechanism in a small tug boat kit, making the cabin removable to service the engine. The boiler is too small to actually work, but Scotty noted that the boat runs fine on compressed air from a line input, and that the engine really drives the propeller shaft. In the photo, the cabin has been removed and sits in front of the placard so that viewers can take a look at the tiny steam engine inside.
