Follow the diagram and stack the pieces together onto the axle.
Again, gluing them together is optional for this step.
The “face up” text will face away from
the spiral ramp during final assembly.
The hubs are sized so it fits into the
final assembly only one way.
The holes do not line up
vertically! They step-
down, to help roll the ball
out at the top of the track.

Pop out the drive gear pieces from the wooden
carrier board and assemble them in the order
shown. Glue is not necessary (but optional).
Let’s start with the glued parts. Glue the diamond to it’s shadow marked on the spiral. For
the bottom rail assembly, glue the narrow “U” to the larger “U”. Finally, for the top rail
assembly, glue the thin sliver to the thicker one.
