Climes of Massillon vacuum engine restoration. By: DJoksch Date: June 8, 2024, 5:01 pm --------------------------------------------------------- This was an earlier EBay purchase post where I learned about its history and origin. The cylinder was made from spiral wound HVAC tubing so I imagine he had this in his shop. I’m improvising with a cylinder design I used in my Stirling engines. The fins are press fit. This engine is really just a pattern since I decided it’s to far gone to restore. *****************************************************
