Where it all began!

I wish I had a link to share right now, but I don't... Anyway, a few years back I did some research into exactly how the Flyer's engine was built. Amazing stuff. It was mostly iron, not steel. The only real metal working tool used was a drill press. They decided on a four cylinder engine because that would mean a flat crankshaft, so the crankshaft could be chain-drilled out a single sheet of iron.
