Try moving a motor shaft with a small gear spinning a large one some time. The motion is smoother because it takes less effort to move the large one. You don't move it as far but the mechanical advantage is huge. Will that actually reduce the friction?.... I have to think about that one a little. It certainly smooths out the bumps and clunky motor opperation.
