Plans for building Leonardo's Gravity Powered Engine
da Vinci Trebuchet Build your own working model medieval trebuchet with these detailed, easy to follow plans and instructions. Inspired by the great war machines and siege engines of Leonardo da Vinci , this beautiful da Vinci Trebuchet stands over 14 inches tall in the cocked position, 24 inches tall in the fired position and will hurl a projectile up to 60 feet. Engineered with an open counterweight cabinet, the da Vinci Trebuchet allows you to vary the weight for range and trajectory adjustment. Fire with an empty counterweight for indoor use, or add weight (nuts, bolts, scrap lead, iron or steel, sand, or small rocks) for increased range. Uses common, inexpensive and easy to find building materials, available at your local hardware store or home center. Basic woodworking skills and tools are required, but the straight forward design requires no complicated layout or joinery. This trebuchet plans package includes a complete shopping list of materials, measured drawings and dimensions of all parts, step-by-step assembly drawings and instructions, as well as firing and tuning instructions.
