• Bruce. Thank you!
  
  Gil. Thank you!
  
  Regarding lubrication, for hot air engines....
  
  I see a lot of differing ideas. And, I often try them out. Always returning to my old favourite. (Suggested by Reid, many years ago).
  
  If it is metal on metal. Rotating, or sliding. I use 5w-30 full synthetic. As in my car.
  
  The only variant is this engine......

  The displacer is moved, only, by the impulses from the power piston.
   It will only run, with half a drop of this oil on it's horizontal displacer shaft.
  
  
  
  
  Most of my engines have graphite pistons. So, need no cylinder lubrication.
  
  I never use graphite powder on power pistons, preferring an oil film to seal the running clearance.

• David, those are some sharp stirling and I like the repurposing of materials. Thanks for the tips on running and for the excellent table

• Thanks, David. I have also been using Mobil 1 synthetic 0W-20 or 0W-30.
  These modern synthetics are great and they don't gum up after a year or two of sitting.

  Almost 10 years ago. When the Huxtable arrived, from Australia.....
