A DIY Desktop Trebuchet is an excellent beginner-to-intermediate woodworking project that scales a medieval siege engine down to tabletop size. It utilizes gravity via a counterweight to fling light projectiles like marbles or paper balls. Building one helps teach fundamental physics principles—specifically the transfer of gravitational potential energy into kinetic energy. Core Mechanics & Dimensions
To ensure your mini trebuchet works efficiently, your build must respect precise structural ratios.
The Golden Ratio (3.75:1): The pivot point of the throwing arm should be split unevenly. The longer releasing side of the arm must be 3.75 times longer than the short counterweight side.
Sling Length: The length of the fabric sling cord must exactly match the length of the long end of the throwing arm.
The Counterweight Rule: For maximum distance, the counterweight box should ideally weigh roughly 133 times more than your chosen projectile. Step-by-Step Construction Guide 1. Cut the Frame Components How to Build a Trebuchet | MythBusters
