Siege tower

Siege Tower Kit

Pathfinders' innovative wooden science kits build working replicas of the most infamous and powerful, medieval siege engines, the Siege Tower, the Catapult and the Trebuchet. Weapons that once smashed castle and fortress walls changing the course of many a kingdom! Building the kits allow children and adults to explore the link between design, materials and technology. A wonderful lesson in how basic mechanical principles turned simple materials into very useful and effective tools. Pathfinders' kits are designed by Derek Wulff, a science educator in British Columbia, and made in Canada. The kits are based on historic designs. The kits use only wood and rope. Pieces are joined by wooden dowels, not screws or nails. No elastic, rubber, motor or batteries are used to create the movement of this device. All pieces are pre-cut and drilled requiring only wood or white glue to assemble. The instructions are detailed and complete with educational notes about the siege engine. When completed, the mighty Siege Tower Kit features a working 5" catpult on top, a drawbridge and ladders. It is 15" tall, 6" wide and 7" deep. This kit is suitable for children 10 and older taking an hour or two to complete. Safety instructions are included and children are recommended to use under adult supervision. While these scale models will only be smashing down imaginary castle walls, they are loads of fun to build and use.
