A lot of the universal joints are not connected at one end. They should be attached to
the nearest axle. 

There are 2 3 stud axles sticking out on either side of the arm on the segment mounted
to the turntable. they should not be sticking out, push them in. They should go into
the red #2 connector.

The worm gear sitting on the ground is supposed to be on the 8 stud axle with stop
behind the turntable.

The 3 yellow axle connectors sitting on the ground are supposed to go on the pneumatic
valves.
