Modified OKMO / Microcosm J07 Miniature Stirling Engine
A very nice Miniature Stirling Engine it was a real 'dancer' across the table turning and spinning on its fuel tank so I cut and put some 4" x 4" timber in my 4 jaw chuck and bored it out to a tight fit on the lathe for the spirits tank and routed it, then stained and varnished the wood plinth. There was also a fairly significant secondary flame flareup from the spirits tanks breather hole when the spirits warmed up enough to create more vapour exiting the breather hole. I extended with a small section of K&S aluminium hollow tube through the breather hole (drilled out slightly) and put a bend in the piping and flared it on the inside for a very tight and snug fit which completely solved the secondary vapour flame.
