Notes

  • 8 mm pinion, pitch radius 12 mm (9 teeth to the wheel's 30 pin positions), Ø6 bore. Its tooth spaces are the envelope of the Ø4 pins as it rolls both outside the pin circle (centres 52 mm apart) and inside it (28 mm), so it clears the pins in either mesh.
  • Xem Studio design following Brown's figure; true size, no printing allowance (apply your own to the mating features).
