Carpenter builds wood model of 9-cylinder radial engine

Have you ever wondered how a radial engine works?

A carpenter has built a model of a 9-cylinder radial engine. Ian Jimmerson apparently built this amazing project in his garage or workshop and everything appears to move just as it would in the real thing. But best of all, in the videos he very carefully explains how all of the parts work together.

In the first video he tells us about the design of the engines, and in Part 2 he goes into more detail and animates it with an electric drill.

Most of the earlier air tankers used various configurations of radial engines. For example, the P2Vs had Wright R-3350-26W Cyclone-18 18-cylinder engines. Some of the C-119s also had that same engine, but others had a Pratt & Whitney R-4360 Wasp Major with a large 28-cylinder supercharged air-cooled four-row radial piston engine designed and built during World War II.
