Make a PVC Catapult




In this I will show you how to make a simple catapult out of PVC pipe.
All the materials you will need are:
4 1" PVC pipes
4 4” PVC pipes
6 3” PVC pipes
5 corner pieces
4 T connectors
3 end pieces
1 4 way connector
4 2 way connectors
Duct tape

To cut PVC pipe, you just need to buy a large pipe of it from a hardware store and cut it with a hack-saw.

Step 1: Step 1: the Base

For this one you will need:
2 4” pipes
4 3” pipes
4 Corner pieces
2 T connectors.
Assemble them like in the picture shown.

Step 2: Step 2: Add Supports

For this one you will need:
4 1” pipes
2 2” pipes
2 T connectors
4 2-way connectors
And assemble it like the picture below, and add them to the base as also described in the picture below.

Step 3: Step 3: Add Catapult

For this you need:
2 4” pipes
2 3” pipes
1 4-way connector
2 end pieces
1 corner piece

Then add the duct tape to the end piece to make the basket for the catapult, like in the other picture below.

Step 4: Finished

Now add that onto the rest of the catapult, and you are finished.

    how did u modify it to be a real catapult?


    Reply 3 years ago

    I made some pipes longer, and added bungee chords so it would be slightly more efficient. But, right now, I think that this project might be able to be classified as a catapult even though you have to use nothing but your arm to launch it.

    The problem is that it's not a catapult. It doesn't use tension to launch the object. Instead you have to hit one end to launch it.

    Why does it say in all the materials you need you need
    4 1" PVC pipes
    4 4” PVC pipes
    6 3” PVC pipes
    But on the second step it says you need 2 2” pipes?
