Step 2 – Assemble layshaft

Parts required:
  • Machined layshaft x 1
  • Wheel gear x 1
  • Brass hobb wheel x 1
  • M3x5 set screw x 1
  • MR95 bearings x 2
  • Cyancrolite adhesive

2.1 Partially insert layshaft into wheel gear as shown.

2.2 Sparingly apply a little cyanoacrylate adhesive onto and around the shaft and onto the machined flat where the gear will be in its final position.

NOTE: Apply the cyanoacrylate only where the wheel gear will be positioned on the shaft as shown by the red marker in the image.

2.3 Immediately after applying the cyanoacrylate push the gear fully home as shown below
