The Tk3 Model Trebuchet Kit

Modern Materials for Medieval Machinery

Build your own working trebuchet with professionally engineered materials in this kit.

In only two or three hours with just a pair of scissors and some glue, you will complete a working trebuchet capable of hauling the included wooden missiles over 40 feet.

The TK3 model trebuchet can demonstrate all the principles of the trebuchet as either a hanging counterweight machine a wheeled fixed counterweight machine.

Switch between both models and test to see which is more powerful and efficient.

• Detailed instructions are complete with diagrams, photos, tuning tips, and even efficiency equations for calculating your maximum theoretical range.
• All parts are pre-cut, pre-drilled and can be assembled to a finished model in one evening (plus glue drying time).
• Sanding and filing required. Some dowels may require sizing to fit. Sand paper, file, and wood glue not included.
• The counterweight box is supplied, but you'll need to supply the counterweight material to fill the box. For best performance, we recommend using 360 pennies for counterweight and/or two 1.25 lb. barbel weights (barbel mounting inserts also included).
• Size: 15" throwing arm; 18"L x 9"W x 13"H.

Recommended ages: 12 and up.
