Ugears Tower Windmill**

Ages 14+

The model is powered by a removable rubber band motor. Once the motor is removed, the Windmill can work in a manual mode that allows you to observe and examine the fascinating complex mechanism in detail.

The rubber band motor drives the sails by means of a screw conveyor (worm feeder) and gear transmission. The design of the gear transmission includes a flexure link, the type of chain drive assembled out of many small links. The full-fledged chain drive made out of plywood has never been used in the Ugears models before.

Resembling a spiral staircase, the rotating base of the arched tower is a part of the screw conveyor mechanism that is a chief part of the models mechanism. Fascinating mechanics of the moving gears will captivate your attention for a long time.
