Converted Model Airplane engine to run on air

[The_Paso_Kid]

I just finished this project. I've seen videos of weed eater engines converted to run on steam or compressed air. I had this old model airplane engine just lying around and decided to give it a try. I began by machining a plug/intake to go on the cylinder head and then an eccentric cam and connecting rod. Then I started fitting and measuring as I went. It does not look pretty but it works.

Here is a video clip of it running, the uni-flow design of this engine creates an interesting sound.
