  • 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.

  • weak shit

  • @master0987654321100 Says the person with 0 videos who has nothing better to do than post on a video of a freshman extra credit project?

  • That's pretty cool man

  • nice

    

  • sorta a trebuchet firing sling type thing with a torsion feel

  • But, will it blend?

  • i suggest a better system for getting the arm down you are going to knock your head off some day

  • about how many times did you wrap the ropes?

  • @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.

  • when u loaded it I could picture u slipping and the arm coming back up and taken ur face off,lol...pretty sweet though

  • What did you use to keep the rods holding your rope from digging into he wood?

  • @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.

  • 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...

  • dude sick!

  • 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.

  • But, will it blend?

  • how far does it fire a tennis ball plzzzzzzzzzzzzzz reply

  • how thick is the rope and how long of rope would i need if i made a 4 feet one instead of 8 feet

  • show me how to make one

  • you should have used a old boat winch to set it, your method is looking for a good hard smack on the chin.

  • which is the best catapult to make a trebuchet or a catapult like this plzzzzzzzz reply

  • @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.

  • @attackofthehog its only 4feet high by 4 feet wide but ive secured it loads

  • @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.

  • whats the length of the swing arm

  • @nerf986 well, he said in the video it's about 6 feet, look at 1:06 to see what I mean.

  • @nerf986 6ft

    

  • would you be able to tell me the measurements of the catapult plzz reply

  • @nerf986 I put the dimensions in the description.

  • @nerf986 the basic frame is approximately 8'x3'. The swing arm is 6ft long and it is wrapped with 1/2" nylon rope.

  • u shoud get a winch for that

  • The dogs want their balls back man.

  • best dog toy ever

  • Dogs: "Untie me, dammit, so I can catch the balls that kid keeps throwing!!!"

  • I bet your neighbors are like, "stop shooting shit in to my yard!" lol. nice vid.

  • 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.

  • Hey I read about this in the newspaper "man killed by flying lacrosse ball".

  • I Want To See How It Will Shoot A Bowling Ball Maxed Tention....Oh Yea Neighbours; Man: Hooney Why Is There A Hole In The Wall ? Woman: I Think The Neighbour Is Declareing WAR ! Man: I Will Get Him For This ! "5 Mins Later" Man: I Was THIS Close To Get Him....Then I Took An Arrow In The Knee!

  • Best. Extra. Credit. Project. Ever.

  • Best. Extra. Credit. Project. Ever.

  • Thumbs up for Elmo

  • Tell your dad I said, "Nice Yard!"

  • @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

  • @m5burndt perfect lawn!

  • @MrSmokeythedragon And a lot of work by the way. Keeping it green is almost impossible in the missouri heat.

  • @m5burndt ahh that makes sense and ya though gret job with it

  • thumbs up if you thout it hit the bird at : 1:53

  • thumbs up if you thout it hit the bird at : 1:54

  • Absolutely Awsome. You might want to add a crank for pulling the arm down. Save alot of work for you and less hazardus, Thanks for sharing

  • Fire in the Hole !!

  • The ultimate dog toy

  • @CoolUserName2010 lol lmao

  • How much rope did you use to create the power?

  • @TH3666SN1P3R I used 50 ft. of 1/2" nylon rope.

  • should put a shock proof camera in the sling and fire it whilst recording.

    

  • EMM ,,, CAN YOU TELL MI PLISSS ALL THE STEPS YOU TOOK TO MAKE IT ... i NEED TO DO ONE TOO .... PLISSS :)

  • @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.

  • this is why everybody needs a nerdy friend. lol

  • 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.

  • @CjStudiosInc Other than that, i think you should be able to get a good idea of how it works by looking at the video.

  • how did you make the basket

  • you should put a hoop somewhere and see if you can make a basket :D

  • ya lacrosse rules!!!!!

  • I had forgotten about the catapult Mr Johnston had! He was convinced you built that thing!

  • i have a similar project!

    how did you build that??

  • @TheCatapults Um, it involved a surplus of partially rotten wood, a box of screws, some rope, and a lot of free time. haha.

  • That's torsion catapult, trebuchet hybrid

  • Whow I wouldnt throw bricks with that thing man... That's not safe!!!

    Im serious.

  • @wishcraft4u2 Yeah, i'm pretty sure most heavy objects flung from this thing have the potential to do some damage.

  • @wishcraft4u2 not in a neighborhood anyway, but in a big open field it would be sweet, as would flaming projectiles :D

  • You have to make it so much more tight

  • 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!

  • @m5burndt Thanks a lot. 

  • @m5burndt be sure to post a video when you have it made :D

  • I'm am very Inspired by this, and I was wondering what type of rope you used, and what the length of the rope was.

    Thanks.
