136 Masterpiece 3 • The LEGO Turning Machine

Putting It All Together

Let’s connect all the sub-assemblies and finalize the machine by adding the RCX and
some electric cables. Be careful to place the various parts correctly on the baseplate so
that the required distance and nearness are maintained. Watch out for the electric cables
interfering with the correct movements of the motors; the tape should be free to move
either direction smoothly.

Final Step 0

Locate the previously built
Direction Control and Direction
Control II sub-assemblies, and
attach the axle with the 8T gear
(not visible) to the 40T gear as
shown.
