This engine was built during the horrendous snows of the 2018 winter months in my garden workshop (photo 1). As with all my hot air engines they are cheap to build, mostly from scrap. This is my 5th attempt and can be seen running on YouTube along with my other large Stirling engines, running in the workshop or at shows. The only bought in casting is the 9 inch flywheel casting from eBay. It was theoretically cheap, except for the heating costs of keeping a large workshop and me alive - but only just!
