How to Make a Torsion Catapult – Table top size Mangonel

Thu, Mar 11, 2010

Woodworking Plans Videos

This is a great little catapult that uses torsion from twisted rope or string. It is more accurate to the types of catapults used in the middle ages because they didn’t have rubber bands back then but they did have rope. The rope can generate enormous force that is used to hurl a projectile. This type of catapult is more specifically called a Mangonel. Lots more catapult stuff on my website: www.stormthecastle.com and a web based tutorial with complete plans, instructions and pictures for this catapult is coming soon.

    Hi! I was wondering as to how you made the throw arm stay in an up position.. cuz my partner and I tried wrapping the rope around the throw arm but the throw arm remains on the ground :(

    When you twist the string the arm will go up. If you already twisted the string then you went in the wrong direction with the twisting!

    I can’t remember exactly, I have a video of it on my channel somewhere. I believe it was around 15 feet.

    thank you for this video i am making this for my science project !
    BUT right now i am trying to string it together but what i dont understand is how your supposed to wrap it around the pegs and the tutorial you made doesnt make sense because the pegs are upright whereas in the real model they are on the sides of the catapult! please please help i have untill friday! :( so, how are you supposed to keep the pegs on the side without covering the holes?
