Building an Inverted Pendulum System The Ups and Downs of Defying Gravity…

The Nordex gears showed up today.  They are incredible!!  They are so light they feel like they are made from plastic.  The set screws will make it really easy to attach them to the shafts, also.  Still have one problem to resolve, though.  The gear holes are 1/4 inch, and the motor shaft is 6 mm.  Just slightly different, but enough that the gear would wobble as it turns.
