It is just meant to be spun with your finger tip on the exposed gear, The gear ratio is right about 2-1 so approx 1/4 turn of the exposed gear results in 1/2 turn (180 degrees) of the arrow (Sorry for the prolonged silence :-( )

simply assemble it with the short pin for the larger gear and the long pin for the small gear and arrow. it is just a couple gears that drive the always right arrow. a hand toy is all. The arrow has the illusion of always pointing right
