Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Comments on quality and potential improvements make me chuckle. I recently bought a desktop version of the stirling fan offered by Stirlingkit and others for $129.
When I first ran it, there were a couple of alignment  tweaks that made it run smoother, but beyond that I’ve resisted the urge to update the parameters beyond what they were. Let’s keep in mind they were produced inexpensively in workshops using mostly hand labor.
The kinds of improvements we are tempted by are akin to putting power disc brakes and independent suspension on a ‘32 hot rod.  At some point you lose the baby with the bath water.
