To build a gearbox you need large and small gears. The power source is attached to a rod, on the rod is the large gear. Put a rod above the first one and attach a small gear onto it (make sure the gears are interlocked with each other) then put another large gear on the rod with the small gear. Then repeat this so large gears always spins the small gears. Hope that helped. (i dont know how to make one with gears)
