Step 1: Materials
To build this catapult, you will need some of the following materials. Keep in mind these can be variable depending on what you have available (i.e. arms to pivot on, drill sizes, etc). Five 2-foot planks of wood (pref. 2x4) Two 3-foot planks of wood (pref.
Step 2: Building the Base
First, take one of the three feet pieces of wood and lay it out straight. At this point you'd have two options; you can either connect the pieces of wood directly with screws, or you can connect them with braces, again using screws. We recommend using braces as it is likely to make your catapult more stable.
Step 3: Building the Arm House
The "arm house" is the part of the catapult that holds the pivot arm (a metal pole in our case) as well as the "stopper" which is essentially the most important part of a catapult, as it transfers energy from the arm to the ball ( think of inertia and moving cars, what happens when you get into an accident?!). To start with, you're going to need to place the third two-foot piece of wood standing straight up off of one of the three-foot pieces of wood, as can be seen in the attached picture (yes, it's a duplicate!) Place it approximately in the middle of the three-foot piece of wood. Screws will not work here, you NEED metal braces for this point; screws would either be too long and protrude from the bottom, or would be too short and be ripped form the wood upon impact of the arm. Do the same for the other three-foot piece of wood with the fourth two-foot piece of wood.
Step 4: Constructing the Arm and the Spring Holders
Depending on what you chose to use for an arm, this step may differ slightly or completely for you. To build a replica of our catapult, keep reading. You're going to need another two-foot piece of wood to use as the arm.
Step 5: Tighten, Seal, and Finish
Make sure you go around and ensure that no pieces of your catapult move too easily. You can tighten or slightly modify in places where you need to, just make sure everything is stable! Next, you're going to want some form of arm-stopper-protection. As you can see, we use duct tape.
Step 6: Launch Day!
Now that everything is connected, secured, and finished up, you are able to launch your golf balls.
