Please rate good or bad, blatent slags deleted this is a low budget holiday project maybe more..... A quick clip of the placement and options for top of motor. From all the machines I have looked at none use component stacked cold end of displacer chamber so with seals I hope this format will allow pressure over 100psi to be added. The 8-hole flange and machined surfaces will seal without gaskets even so with high grade gasket sheet and redundant o-rings I am expecting some actual power output on scale with a St-5 or Steele stirling typ unit less the complex drive gear involved for scaled up output. Making a large version has been goal from the start so these should make excellent demo's of using modern manufacturing effectivly to cut costs. I can't wait to compare gases like helium and pressures at 200psi cold! Knowing you can do something with proper research is all you need to start a new project or direction in life. Go for it! and the more people balk the harder you assure your success.
