Step 2: Break two short pieces (same length) and one longer piece of the second pair of chopsticks and tape them to the base as shown in the picture below. Step 3: Join the other ends of the sticks you taped together to form a 3-dimensional triangle. Step 5: Attach the catapult arm to the frame and tie a rubber band around the catapult arm and the top of the triangle. I’m extremely impressed with your writing skills and also with the layout on your blog. Today we’ll be setting aside the circuits and solder for a little while in favor of good old fashioned wood and bungee chords to make this backyard catapult. The swing arm is a 28-inch beam with the broom handle running through a hole in the bottom and a cardboard cup at the top. This seams like alot of effort to build something significantly less effective than even a human arm. At this rate I’d might submit my trebuchet which is made only from various types of computer memory boards. I don’t think that a 10 year old boy can make this alone as effortlessly as you guys put it. Kids will build their own catapult and see how far it will launch small objects (all supplies provided). Made possible with funding from the Institute of Museum and Library Servicesthrough the Washington State Library, Office of the Secretary of State. This tutorial on how to build a catapult takes you through all the steps in showing you how to do it.
Note From Will: If you are looking to buy a Siege Engine kit that you can make yourself you should check out my siege engine store. Parts List: You don't need a whole lot of parts or tools to make this catapult and this is just a suggested list and these are the parts I use to make the catapult in this tutorial. 8 pieces of wood 6 inches long ( two of these pieces have the ends cut at 45 degree angles - I will explain more about these. About the metal bar from the axle: This is what I am using but you can use almost anything similar. Complete project with step by step assembly instructions, blueprints and a video for making this powerful 3 foot catapult.

To change things up from my regular posts, I decided to write instructions on how to make a simple catapult.
When finished, I found that the best items to launch from this type of catapult was mini marshmallows commonly found for a few dollars at a grocery store.
I chose a simple design that would be easy for the boys to follow and would allow plenty of time to launch marshmallows at a target. Step 2 – Tie another rubber band tightly around the opposite end so all 7 sticks are bound together. Step 4 – Insert the 7 sticks banded together through the 2 stick bundle as shown in the illustration below.

You might discover the item impossible to understand woodworking not having all the information in addition to expertise the fact that you will get from a woodworking teacher. You can make one of these catapults with just a few pieces of wood and a little bit of know how. This is going to be the pivot point for the catapult arm so you need something thin and strong. A mangonel is a type of catapult that is true to the real catapults they made in the Middle Ages and Medieval Times because they didn't have rubber bands! This is a great example of making a catapult without using any nails or glue and creating a neat little catapult to have fun with! It was extraordinarily powerful and was easier for military engineers to build because it used gravity as the energy source. Including detailed diagrams and supply lists, Gurstelle's simple, step-by-step instructions help workshop warriors at any skill level achieve impressively powerful results. The mere presence of this striking machine on your desk will induce fear and respect among your peers.
It is the Paper Castle and it has everything you could want in a castle making project including all the art work you can download. I’m a Den Leader for my local Webelos cub scouts group and we are working on the engineering activity badge. Many designs (including the one provided in the scout handbook) were fairly complex and would require a long time to built.
This catapult was built strictly out of office supplies (By web visitor Brandon N.) and he has also built a trebuchet! Find out how the ancients were able to use nothing but wood and ropes to build machines that could hurl heavy stones great distances.
This kit includes everything you need except for glue and a few simple tools like scissors, sandpaper, a file (a utility knife would be helpful too) and about two or three hours of your time from start to finish. Made from high quality knot free Basswood, this Ballista is a great addition to any homemade artillery collection. If you have wood glue or someone to help you with hot glue, you can use that instead of the tape. You can change the angle the catapult shoots from by sitting it on a notebook that you can tilt. The bungee chord should be stretched from an eye hook on the swing arm and one on the base.
If you are creative there is a whole host of parts and things you could use instead of these parts.
Here are some suggested things you could use: very firm coathanger wire - the cut off blade of a screwdriver, the metal bar handle from a bucket.
Load it up with the included wooden balls or get creative with marshmallows, coffee creamers, erasers and more to see how many cubicles they can soar above before landing. All you'll need is glue, scissors and a steady hand to construct this wooden, Canadian-made siege engine kit.

Take charge and besiege your opponents with a fully functional, genuine trebuchet for your desk! They absolutely love decorating them with felt pens, and shooting off anything they think won’t put an eye out.
Inspired by Alexander the Great's Artillery of the Macedonian Soldiers, this ballistic firing machine is a working model easily assembled from pre-cut and pre-drilled pieces.
The same should be done to two 14-inch beams, which will allow them to be fitted to the 24-inch beams at a right angle. The strength of the catapult can be adjusted by using a stronger bungee or adjusting the height of the crossbar. There are lots of different ways to power up a catapult and the way I show you in this tutorial is probably the easiest - you need just a rubber band or two. As you can see though it is pretty basic and you don't need a lot to build a basic catapult.
It has a range of about 15 feet and that can be extended with the use of more rubber bands. The finished catapult stands 6" tall x 5" wide x 10" long and will toss assorted stuff (meatballs?) 15 feet or further, depending upon the stuff.
Build a Paper and Cardboard Castle It also has a learning sheet that helps to learn about castles when you are building it. This catapult can be used as a craft idea for kids on a slow weekend or it can be used as a school project.
After following these instructions, it only took the scouts about 10 minutes to complete everything and start participating in trying out their new catapult.

A fun group or family project, once completed you and your friends and family will be experiencing the thrill of flinging projectiles like those medieval machines, but focusing on height, velocity, and distance rather than on knocking down the enemys fortress. Two more beams, a crossbar and angled beam, are added to complete the support system, leaving it prepped to add the swing arm. The professionally designed kit and fully detailed instructions - 10 pages of descriptions and tips, with of photos of every step - makes assembly a breeze. For the truely daring, you can alter characteristics of the trebuchet such as the mass of the clay, the string length, or the amount of the counterweight and can see how the results are affected.
You will also see these concepts in action: levers, inertia, counterweights, friction, and more.
For a more refined look, a little sandpaper and a small, round file would be helpful, but are entirely optional. For example, he used angle irons to support the vertical pieces instead of the forward support & notching which is a great idea.
If you can get some angle iron this will save you the trouble of cutting and notching (much easier!) He also used threaded rod and lock nuts as the rod to support the swing arm. This mighty desktop artillery is capable of hurling the wooden ball projectiles (included) over twenty feet!
This is another great idea and you can pick up threaded rod at any hardware or department store.
