The Backyard Ogre Catapult

This is the Backyard Ogre Catapult

The base of this catapult is two feet long and the throw arm is about three feet long. It is made from 2x3's but you can make it from 2x4's also. It took me about two hours to make it.

This page is all about this catapult and how you can make one yourself.

Safety Note: This is a powerful catapult that uses a bungee cord as its power source. You must use safety precautions when building and using it! And you must absolutely wear safety glasses when firing it off. This is in case the bungee cord breaks. And never fire any type of solid object with it. I use balls of aluminum foil and it works just as well with a tennis ball.

How to Build the OGRE Catapult

A Note about Safety Before Starting! Please use all safety equipment when building and using this catapult! It is very powerful. Wear Safety Glasses and follow all safety rules if you are using tools and power tools. This project should not be done by minors without the supervision of an adult. Please be safe and never fire the catapult at a person or at someones personal property. Never fire any hard projectiles from the catapult.

Above is a picture showing all the parts needed to build the OGRE Catapult. I will describe them and tell you a little bit about them. Lets start at the left. You can see that there are some cut notches and some holes drilled in the wood. I will explain what these are and how to do them.

From Left to Right the wood: (All wood is 2x3) The longest one is not quite 2x3 because I used a scrap of wood that I had but you can use a 2x3.

• 2 pieces each 7 1/2 inches long
• 3 pieces 14 inches long
• 2 pieces 24 inches long
• 1 piece 28 inches long
• 1 piece 10 1/2 inches long

The extra stuff along the bottom:

• a cardboard cup (this holds your projectile)
• 2 large and strong eye hooks
• a bunch of long screws (you can use nails but screws are better)
• a bungee cord that is 24 inches long
• a broom handle, dowel or pipe that is about one inch thick and 12 inches long

Okay, once you have these pieces of wood cut to length lets modify a few of them. This is the hardest part and once you have this done the rest of the catapult goes together very quickly and easily. We are going to cut two of the pieces of wood so we can form them into a joint like that shown below. It's not that hard. All you need is a handsaw, a chisel and some safety glasses and gloves. Making this joint is important because it will make your catapult much stronger.

Okay, continue on and I will show you how to do this cut
