Roman Ballista Plans Build a Working Model Ballista Catapult. Once complete, this Stone Throwing Ballista is 2 feet long and will throw a scale projectile up to 90 feet. This Roman Ballista design allows you to vary the elevation and bow strength for range and trajectory adjustment. Fire it with a soft projectile for indoor use, or a solid one for long range outdoors. Resembling a crossbow, the ballista derives its power from skeins of twisted cord, just like a catapult. The Stone Throwing Ballista is perfect for demonstrating ancient Roman warfare and technology as well as the physics of torsion, ballistics and projectile motion. Ballistas make great science and history projects. 2. Roman Onager Plans Build your own Roman Onager. When built, this Roman Onager stands 12 inches tall in the fired position and will throw a scale projectile up to 50 feet. The most powerful artillery piece in the Roman arsenal and a direct descendent of the Mangonel, the sling equipped Onager took its name from the Persian Wild Donkey because of its powerful "kick" when fired. The Onager is perfect for demonstrating Roman Warfare and technology. 3. da Vinci Spring Catapult Plans Build a Working Model Spring Catapult. The Spring Catapult is based on Leonardo da Vinci’s own design and updated for ease of construction and operation. Once complete, this scale model catapult is over 18 inches long, 12 inches wide and 24 inches high. da Vinci’s Spring Catapult is an interesting study in catapult design. Most ancient catapults used either tension or torsion for motive force. Leonardo’s spring catapult uses tension, converted to torsion, to launch its projectile. The Spring Catapult is perfect for demonstrating ancient design and technology as well as the physics of tension, torsion, and basic machines. This da Vinci Catapult makes a great science or history project. Spring Catapult plans also include a full size cutout template for the catapult’s ratchet. 4. Highland Trebuchet Build a classic hinged counterweight trebuchet. Once complete, this magnificent Highland Trebuchet stands over 36 inches tall and will throw a scale projectile up to 80 feet. Designed with an open counterweight cabinet, the Highland Trebuchet allows you to vary the weight for range and trajectory adjustment. Fire with an empty counterweight for indoor use, or add weight for increased power and range. The Highland Trebuchet is perfect for demonstrating medieval warfare and technology and the physics of leverage, ballistics and projectile motion.
