My REAL catapult

I recently built a Huge catapult at my friends house out of old decking. It is 13 feet long with a 14 foot arm. My friend needs to get the drill fixed so we can finish and until then we are waiting anxiously. It should shoot a large, 10 pound rock about 100 feet. The next time I go over I'm gonna bring my camera and take a video of it, and guess what? It's powered 100% by torsion just like the Romans. It uses 2 inch diameter rope. I also made a Roman Scorpion which uses 1 inch diameter rope and shoots large arrows 100 feet.

Oh I will. Right now I'm just waiting on thicker rope. The rope it uses now is 4 times too thin.
