Rudy Kahoupt water-cooled hot air engine

[Tom Jamboretz]

I decided to take a break from IC engine making and made a water-cooled hot air engine from Rudy Kahoupt's plans. I'm finished with the engine and it ticks along at about 400 RPM on the tach.. It took along time to get rid of all the friction. Lots of beer can shim stock was consumed. Here are a couple of photographs. TJ

Nice looking engine, there is a lot of work there not counting the can opening, do you have a video of it posted somewhere yet, thanks for the show, Lathe Nut

I tried to post video but did not have any luck. Sorry! TJ

Lathe nut, Seems that the video did load. Look under hot air engine in Videos. Sounds like a diesel on the video but not in real life. TJ
