Drive Step 10

Locate and attach the assembly
created in Drive Step 0.

Set the Driving Mechanism sub-assembly off to
the side. You will need this part when you get to Final Step 14.

The Lower Arm Drive

You will assemble the drive mechanism for the lifting arm in two stages. This is the lower half of
the mechanism, which will give a 24:1 speed reduction in order to prevent the flags from being
tossed into the air. It will also serve as an armrest for the lifting arm.
