I had the idea to build something cool to haul my swap meet finds with, and after some starts and stops, I built this Radio Flyer sized rat rod wagon, that I pull with a dog chain. I built the body out of 16g steel, the rear wheels are from a kids trike, the front wheels are kids training wheels. The engine is a plumbing valve, and piping parts. The grill is a brass floor drain cover, surrounded by the base of a fire poker set. The front axle does pivot to turn.
