Spinner Arms Step 3
Locate the Arm Pivot sub-assembly
built previously, and attach it as shown.
The 24t crown gear and 8t gear
should mesh neatly.
Spinner Arms Step 4
Slide the 12t gear, teeth-down, onto the axle
of the Right Gripper sub-assembly, until it meshes
with the gear on the Drive Shaft sub-assembly. You will
want to support the end of the #4 axle with a fingertip as
you do so, to prevent it slipping down from the pressure.
