Nice one Charlie .... but I'd sure get in trouble with that one around here. My Lady already thinks that my Solar One Stirling is just a mechanical noisemaker, so I'm sure one of these would just set her off on the needless noise path once again!
My wife thought I had built a bomb in the garage. 🤠
I am working on mounting it on the board with the Steam Engine Pump. And putting cotton inside the drum to quiet it down.
