The UGears Tower Windmill is an elaborately designed, intricate and well-crafted mechanical model kit, especially suited to the interests of history and literature enthusiasts alike. This vertical windmill-based puzzle speaks to a faraway time and place. Seventeenth- century England is your destination as you explore the wonders of the Tower Windmill, which was inspired by a real mill in Chesterton, England, owned by Sir Edward Peyton, an English landowner and politician. You’ll love assembling this masterpiece, and when you see how the parts fit perfectly together, you won’t feel a need to tilt or fight this particular windmill, unlike the man of La Mancha, Don Quixote. Fashioned in a “Victorian steampunk” style, this Tower Windmill model kit is devised so that a quick turn of the main tower column causes the aerodynamic sails to spin, generating wind. An applied outside wind source can also turn the sails to provide not only long-lasting entertainment but also a unique insight and discussion of the inner workings of an actual windmill. You can remove the rubber-band motor that powers the model to closely observe the mechanics when the windmill is rotated manually. The mechanism is based on a double planetary gear configuration. In such an arrangement, gears are mounted so they revolve around the center of another gear through the use of a carrier. In this complex arrangement, gear motion propels the sails to move. Due to the open architectural design of the main column, you can see the various gears connecting and working together to translate the rotation of the tower to that of the sails. The UGears Tower Windmill enriches learning as well as generating enjoyment.
