Mangonel Catapult

This is a Mangonel Catapult (traction trebuchet) designed by me. All you need is two rubber bands! Attach the square end caps to the rods after inserting them into the catapult. The ratcheting gear goes into the bottom hole where the two holes are located. The ratcheting arm goes above it. Attach the actual launcher arm to the shaft on the far side. Wrap rubber bands around the loops and onto the main part of the body.
