Step 6 2 Gear bearing assembly

1 First assemble a 4.5mm diameter, 28mm thread length bolt and a 32mm gear. I added a little super glue to make sure these parts were locked together.

2 Washers were added for spacing so that the shaft gear aligns with the servo gear. Now thread the bolt along with gear & washers through the gear assembly piece.

3 next add the 60mm bearing

4 add a washer and small split ring who's diameter is smaller than the outside rim of the bearing assembly

5 Loosely hand tighten a nut

6 Add a split washer

Drill a hole in the centre of one end of the aluminium cylinder . Tap this hole with a 1/4" 20 tap (drill size matches the tap). Marry the reverse end of the cylinder to the gear assembly piece as shown in the picture. Locate two predrilled holes in the assembly & mark through to the cylinder end. Drill and tap these two holes (I used an M4 tap). Next locate the screws and tighten.


Finally Mount the round servo attachment onto the servo shaft. Attach a servo motor to the gear assist assembly . Screw the gear shown in orange here onto the round servo attachment using small self tapping screws.
