Let's begin the assembly of our catapult

First gather all your materials and then cut the wood into the required pieces. You can use almost any size wood and I used some scraps of wood that are 1 inch by 1 half inch wide.

Cut it into several pieces like this:

• Cut 3 pieces twelve inches long
• Cut 8 pieces six inches long

Now of the eight pieces you cut that are all six inches long cut two of them like the two in this picture. They are still six inches long but the ends are cut off at 45 degree angles. Make sure you cut the angles as shown.

Assemble the first side of the catapult just like this picture shows. I used glue and screws which is the best but you can improvise any way you want, nails and glue would be fine too. This is the support system for the swinging catapult arm so you want it to be sturdy enough to take a bit of a slapping of the arm against it. The line at "A" shows where the screw is. The line "B" shows the angle wood and the horizontal wood are about lined up on their ends.

Now build the other side but make it a mirror image of the first one. The two of them will look like this picture on the left. See how they mirror each other?

Now connect the two sides of the catapult together using the remaining four 6 inch pieces. The photo at left shows these four pieces. I used screws and glue to make it very strong.

Note: The upright wood pieces (the two vertical ones) are on the insde of the catapult base. Don't build it with these on the outside. It is stronger this way and you can use a shorter piece of iron bar.

Okay, we are doing great and it is starting to look like a catapult:

lets continue on with the assembly
