Beautifully restored pre WW2 aircraft on tour.
Video is a primer on the hobby of building model engines. Featured here is the Atkinson Differential Engine. This engine is built mostly out of barstock aluminum. The flywheel is machined from a 10 pound gym weight.
Two 95 pound anvils are machined out to hold gun powder, placed one on top of the other, sealed with peanut butter and a fuse. The top anvil (shooter) is blown up in the air 300+ feet with a goal of landing as close as possible without hitting the first anvil. Note the last picture with the shooter buried deep.
This is a repleca of engines built near Kansas City in the late 1800's - early 1900's. The engine here is machined out of bar stock materials (no castings). The fuel system is a bubbler with a mix of lantern fuel and alcohol. A fly weight on the side of the flywheel controls the engine speed by holding the exhast valve open giving it a hit & miss common on early engines.
