Marking the Sleeve Bearing Mount Holes

  • Mark 6.5mm from the circumference of the 18mm hole for each sleeve bearing mount hole.
  • Drawing a centerline may be helpful to measure along.

Drilling the Leadscrew Nut Mount Holes

  • Match drill the leadscrew nut mount holes from the leadscrew nut to the block while the leadscrew nut is fitted inside the block for superior alignment.
  • After drilling each hole, tap it and screw in an M5 screw for secure mounting for drilling and superior alignment.

M5 Pilot Holes

  • All pilot holes to be tapped M5x0.8 should have a diameter of 4.5mm
