THE SMALL PINION HAS A SMALL PITCH AND THE GEARS MESHING WITH IT THE SAME SMALL PITCH, AND THE LARGE PINION HAS A LARGE PITCH AND THE GEARS MESHING WITH IT HAVE THE SAME LARGE PITCH. THE COMPOUND PINIONS ARE FINISH CUT BY A ONE PIECE CUTTER WHICH SIMULTANEOUSLY CUTS A PAIR OF TEETH, ONE TOOTH ON THE LARGE PINION AND ONE TOOTH ON THE SMALL PINION, SO THE TEETH ON BOTH PINIONS OF EACH COMPOUND PINION HAVE AN IDENTICAL RADIAL ALIGNMENT RELATION TO EACH OTHER AND ALL THE COMPOUND PINIONS OF THE GEARSET ARE IDENTIAL IN THIS RELATION FOR EQUAL LOAD SHARING.
