Radial Air Engine Compressed Air Engine
Since starting the construction of this engine, I have made some changes to the bore and stroke, which are now 5/8” x 5/8”.
The original concept for this project was taken from a video I saw on YouTube. I took some stills from the video and copied it as best I could from the photographs. This turned out to be a bit of a headache as I had no dimensions to work from. I decided to make it a rotary valve engine and after looking at this site, I realised that I was copying the engine designed by Rudy Kouhoupt. Everything was made except for the rotary valve which I was struggling to design. Then, I had the offer of a set of plans for the valve from another F.A.M.E. member. As it happens, it turned out alright with everything missing each other where it should! The two base plates are a cast iron retort stand base and a piece of scrap from the local scrap yard. All the rest was sourced from scrap except for some of the screws that I had to buy and the propeller. It runs very nicely on 20-30 PSI and has a nice multi-cylinder note to it.

Radial air engine with 5/8 bore x 0.8" stroke. I am undecided as to whether to make it ball and pin, or rotary valve.
