Doc's Mignon Windmill

Hi folks, Doc here. This windmill is another model from the Mignon No. 3 set. It features a freely rotating head assembly on top of the tower, and a clockwork motor beneath the tower platform to move the blades. Power is transferred from the motor's horizontal driveshaft to a short vertical shaft beneath the tower via a pair of helical gears. This shaft is offset from the center of the tower, so a pinion and gear wheel is used to transfer power from this shaft to the main vertical shaft in the tower; this gear combination also serves to further reduce the gearing and thereby the speed of the blades. Finally, I modifed the original design a bit by using a pair of bevel gears in the head assembly to transfer power from the main tower shaft to the horizontal blade shaft.
