Bored out to the diameter of a Red Stripe bottle, which will be my displacer cylinder wall ;)

I knew i should have measured the offset instead of just eyeballing it... I’m not concerned, this is a seat of the pants build... Just disappointed that I missed. Probably did order of operations wrong too...

Still to do:

  • Bore transfer port
  • Power cylinder sleeve
  • Power piston
  • Crankshaft
  • Con rods
  • Displacer cylinder sleeve
  • Decide on displacer material
  • Lots of other stuff
really pleased with the fit of the Red Stripe bottle to the displacer and the top

I think the displacer is all set, but the fit on the power piston to the sleeve is a bit loose, and I haven’t polished the bore yet, so I may have to re-turn the piston.
