Notes

  • Single helical flight, Ø60 outside, 3 mm thick, pitch 60 mm (pitch = outside diameter, the classic proportion), 3 turns (180 mm) on a Ø12 shaft that runs 20 mm past each end.
  • Inclined at 30–40° in water it lifts a pocket per turn; it is a Xem Studio model following Brown's figure.
  • Xem Studio design following Brown's figure; true size, no printing allowance (apply your own to the mating features).
