Thanks to my good friend Evan for helping me build and shoot video of this trebuchet! About three months ago I decided I wanted to build a trebuchet, and this is the result. The arm is about 14' in lengths and the frame stands around 6'-7' tall making it a fairly medium sized trebuchet. The red-painted pop bottles in this video are going around 200' (A distance tediously measured with a 12' measuring tape. Sure, I could have gone back to the shop and gotten a 25' foot one and have been done in half the time, but wheres the fun in that?) Unfortunately, the machine isn't tuned very well and as a result a lot of the energy from the weight box (Which is full of red bricks) is being completely wasted. I'm confident this machine could throw around twice as far if I had the time and initiative to take it all apart a half-dozen times and meticulously size everything for maximum energy transfer to the projectile. But alas, I do not! Sorry if I got a bit overambitious with the ole' video editor for your taste. I decided to have a bit of fun with this one and I am happy with the final product. If this kind of thing is not your cup-of-tea though, I plan on doing some more videos on this machine in the future! If your are watching this video in the future, then go ahead and watch those instead. If not, remember: Patience is a virtue.

Support Will: http://www.stormthecastle.com/support.htm In this tutorial I show you how to make a rubber band powered catapult out of PVC plastic pipe. It is a small desktop sized catapult and easy to make. PVC is plastic pipe that is readily available at all hardware stores and it is very inexpensive. Same thing with all the fittings and elbows you see in the catapult. You can get them right off the shelf and they are very cheap. Just about the only thing you need to make this catapult is some kind of a saw to cut the plastic pipe. It is the perfect catapult project if you don't have any woodworking stuff. I give you a complete parts list so you can get all the parts and put the catapult together quickly and easily. The tutorial and template for this catapult are on my website here: http://www.stormthecastle.com/catapult/how-to-make-a-pvc-catapult.htm About my Channel: I have hundreds of videos covering all kinds of creative projects.

The purpose was to create catapults and a trebuchet to throw tennis balls. The trebuchet launched it 100 feet, the large catapult, 80 feet and the 2 smaller catapults like 8 feet because they are built by inferior people.

** Read Full Article Here - http://goo.gl/9EoS1I Model building is a big part of woodworking. Just like in boat building, woodworkers often make smaller models of the ideas and designs and in the video we make a table top size Trebuchet. ** Like me at Facebook: https://www.facebook.com/WoodWorkWeb ** Follow me on Twitter: https://twitter.com/woodworkweb ** Join me on woodworkweb: http://www.woodworkweb.com ** Connect with me on Google+: http://goo.gl/7fotJq **** Subscribe here - https://www.youtube.com/user/knecht105

This is a short film about the testing of my mini catapult project for the course Introduction to Mechanical Engineering. I tested it with the help of my little nephew. This catapult was also intended for the Mapúa Institute of Technology School of Mechanical Engineering Catapult Competition 2011 for freshmen.

Spent a weekend teaching trebuchet building techniques and assembling a mid-sized catapult with Craftsman at their MAKECation getaway. Then we shot water balloons over the roof of the Lake Arrowhead Resort. Fun.

This video shows the amount of force that is involved after we converted our Medium trebuchet from a hinged to a fixed counterweight. I thought that I could cock the machine by myself since I had no problem cocking it when it was a hinged. It also shows how wheels are very necessary to a fixed.

My friend's daughter, who is also one of my karate students got to build a trebuchet for a class catapult contest at her school, so I offered to help. This is how it turned out. We need to add some heavier counterweights and it will fly much farther. We got ideas for the design from this very helpful site: http://hila.webcentre.ca/projects/trebuchet/index.htm Our model is about 2.5 times the size of the desktop trebuchet on that site. I had a lot of fun building this, now I want to make a big one :-)

I built this catapult in 23 minutes. I tried to do it in ten minutes. I will be posting complete plans for this torsion catapult on my website. You just need some rope and a few pieces of wood. I call this catapult "The Wyvern". When you use twisted rope like this the catapult is called a Mangonel. THe website is stormthecastle.com

A (Mangonel) Siege Onager I constructed as an extra credit project for my ancient history class. It is made out of old wood and some rope. It will chuck almost anything that can fit in the sling. The specs are: 8'x3' dimensions 1/2" nylon rope. "Pin" type firing system

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. If you are having trouble wrapping the rope or string I have a video that shows you exactly how to do it here: http://www.youtube.com/watch?v=PRSBKm1encM 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.

a trebuchet I made as a final project for highschool. I (Freek) did the calculations and design of the trebuchet, starting with a small test and then medium sized prototype we tested the capabilities and the forces that would work on the trebuchet after a final design was made we started construction. and together with Gertjan who did research on other weapons of our essay we tested it... at the school yard :) (yes we actually got permission to wreck the playfield :D) final specs range about 60 meters, up to 80 meters with a lot of extra weight (as can be seen in the end of the video) that is with a one kilogram steel jeux de boules ball. about 2 meter high frame (i am sorry i do not have the exact sizes anymore) over 4 meters with the arm in upright position. weight in the bucket, standard 150 kilo's final tests estemated weigt in the 300 kg range. (wet sand, with tiles for extra mass) it was alot of fun to build. and even more fun to use, if you have your own trebuchet please post a videoresponse.

I started making small desktop trebuchets (starting with pop sickle sticks and working my way up to basswood). Then I had to tear down the white picket fence around my yard (because it was falling apart). What to do with all that wood? I don't know, how about make a trebuchet!

This is a fast and easy trebuchet project that you can make in a couple of hours. It fires an object the size of a tennis ball and is pretty powerful. I built it with simplicity in mind. A few pieces of wood and 2x4's and powered by dumbbells. The project is also complete in a web based tutorial here: http://www.stormthecastle.com/trebuchet/Fast-easy-tennis-ball-trebuchet-part-1.htm I have no idea how far it will throw a tennis ball. didn't take it outside, just bounced the tennis ball off the walls inside.

As featured on http://www.geeksaresexy.net Mark Winkler decided, in infinite wisdom, to spend six months building a full-scale trebuchet. In the next installment of Geeks Are Sexy's series on crazy inventions and crazy inventors, we introduce Mark's brainchild, "Mongo, the Trebuchet." Mongo often launches watermelons, but the 25Gs of force put on the melon as it launches often causes it to burst in mid-air. In the video, Mark throws a 16 pound (7.25 kg) fireball yes fireball about 250 meters or so with 1200 pounds (550kg) of counterweight. (Mongo can handle up to 1600 pounds/725kg of counterweight.)
