Step 8 Motor Hubs

The next step is to couple the legs to the motors.  I found these handy 5mm mounting hubs, which were perfect for the job.  I drilled four holes in a square on one side of each pair of legs, and screwed the hub to the legs with 4/40 screws.  To fix the motors to the legs, you simply line up the flat side of the motor shaft with the screw in the hub, and tighten the screw.
