@LegoScout09 I'm not sure, i know it was 1/2" rope, and i think it was about 50'. The frame was about 3.5' wide, so 50/3.5=14.285so about 14 times. Really you want to just wrap as many times as you can fit.
@attackofthehog Nothing, which was a bad idea. As a result it dug very deep grooves into the wood and really tore it up. I would suggest reinforcing that area with a respectably sized steel plate.
how many times do you wrap something of this size? im made a catapult with an arm about 4.5 feet long and am not sure about the torsion part of it. and btw NICE JOB!!
@LegoScout09 I no longer have this cannon because i was once trying to push its limits and it snapped in half due to the extreme torque. As for most of the questions about dimension and stuff: From looking at the footage your guess is as good as mine. If you look at the footage near the beginning it should be easy to make good judgements.
@nerf986 It really depends on your requirements/purposes such as what kind of projectile you want to fire and how far. As a generalization, torsional catapults like this are good for lighter objects, but can throw them relatively fast. Gravity catapults (like trebuchets or something that uses a really heavy weight) are good for throwing really heavy objects that dont need to go quite as fast.
@nerf986 In my opinion trebuchets are funner to build and tinker with, but they are also a lot more complicated to built. Onagers are simpler to make, but there really isn't many ways to adjust one without taking it apart. If you want to build the trebuchet I would personally recommend you make it no higher than 15 feet tall with a 500-600lb counterweight, but not much smaller than 10ft tall, at least for your first one.
@nerf986 Also trebuchets are much much easier funner, and safer to build with a friend. Finally if you build a trebuchet, it will work much better if your throwing arm has the 5/1 ratio. This ratio dictates where you put your fulcrum, ie. if your arm is 15ft long then you will put your fulcrum three feet in.A wheeled frame will also increase the distance your projectile goes.
@nerf986 The last thing to remember is support, I cannot stress how important this is! See to it that all of the joints are well secured, and support the crap out of the thing. Believe me, it is no fun at all when your trebuchet topples to the ground (I have had this happen and it was not pleasant) Good luck with what ever you build! and if you ever need help send me a message, I just might be able to solve the problem.
Nice job on your onager! I would imagine you know this, but you can maximize power by adding more rope to the rope bundle. If you like to watch things explode, the perfect projectile would be a 2-4 pound pumpkin.

@AntLyon Actually i'm the one in charge of the lawn/yard care in my family. I have a small business providing such services commercially. I have to say the yard was looking pretty nice when this was filmed :D
@danielaalaniss By looking at the video, and the other comments i responded too, it shouldn't be too hard to figure out the general design and layout. There is nothing sacred about the dimensions i used. Feel free to use my video and design as a general guidline, but i recommend you evaluate what you are looking to get out of it and come up with a design to suit your personal needs.
What are the dimensions of the wood that you're using, and how far do you think a pupmkin will go? Please respond because I have an upcoming pumpkin launch with Troop 2 boyscouts of America and I am a patrol leader.
@CjStudiosInc it is mainly 2x6's and 2x4's. The wood i used was somewhat rotten and as a result it could not take a lot of torque. Theoretically, the distance you can throw an object is only limited by how much torsional force you can put on the ropes. If you construct a device similar to what i build, only out of fresh wood, with a longer metal rod you could put a lot of force on it.
@m5burndt Thanks for the info, but do you have a plans that I could use to find out how much wood I need and how long/wide/big the wood will have to be?
@CjStudiosInc Sorry, i dont have plans drawn up. The dimensions of the catapult in this video are 3 feet wide by 8 feet long (the base). The base was constructed with 2x6's, the sides of the bases were doubled 8ft long 2x6's. You will need to drill large holes (3 or 4 inch) through those doubled 2x6's to string the ropes through, i recommend reinforcing the areas where the holes are drilled. Also, wedge a good sized piece of wood next to the ropes to keep the sides from caving in from the force.
Actually its just typical home depot 1/2" nylon rope. I think it was about 50 feet total but i cannot remember. This is actually a somewhat inefficient catapult because it was constructed as an extra credit project out of some old rotten wood laying around. I am planning on constructing a new one complete with a 12v truck winch to crank the arm for me so i dont kill myself!
it's a nice one. i suggest you to stay away from the throwing rod when it is in action and be careful when you are pulling it back.

that is one dangerous way to cock that.. if ya ever slip its got enough force to kill ya.
they were cocked then many ppl cranked the ratchet to tighten the rope...
