1. A couple of nasty looking boards.
2. A 1/2" diameter dowel.
3. A short piece of a 2x2.
4. A length of thin rope.
5. Two 1" wood screws.
6. A 1/2" drill bit.
7. A 3/4" spade bit.
8. A drill or drill press.
9. A table saw or circular saw or handsaw.
10. A miter saw or miter box or motorized miter box
11. Scissors.
12. A screwdriver
13. A lighter.
14. A pencil.
15. A roll of tape.
16. A ruler.
17. A miniature enemy.

Step 2: Preparing your boards.

First, use your table saw to cut your nasty looking boards into two 7 1/2" x 3 1/2" rectangles.
Once you've done this, tape the two boards together with the broad sides touching, then, with your pencil, mark the two longer edges: "top" and "bottom", and the two shorter edges "front" and "back".
Measure 1" up from the "bottom" and 2" from the "front" and draw an X. Next, measure 1" down from the "top" and 3" from the "front" and draw another X.

Next, with your boards still taped together, measure 1/2" up from the "bottom" and 1/2" from the "back" of the board and draw a V. Flip your taped boards over and draw another V in exactly the same place on the other side.
Last, measure 3 1/2" from the "front" and 1 1/2" from the "bottom" and draw a T. Do the same on the other side.
Fit your 1/2" bit into your drill.
Drill the Xs all the way through.
Drill the Vs to a 1/4" depth.
Drive a screw into each of the Ts so about 1/4" sticks out.
Separate the two boards.

They should look like a mirror image of each other.

Step 3: Preparing your dowels

Next, use your miter saw to cut your dowel into two 5 1/4" lengths and one 4 1/4" length.

Great idea. I built a zillion rubber band guns for my kids, now I can build catapults for my grandson.
Hi Pariahcycle,
I built a couple of your catapults. Fun little project and my boys will have tons of fun to come as well.
A few comments though:
1) The upper dowel position didn't work for me. I had to move the upper dowel to be right above the lower one. Otherwise, the catapult would have thrown its ammunition (little foam balls in our case) only onto itself.
2) I didn't have a string, and used multiple long rubber bands instead.
3) I sanded the lower shaft so that the catapult arm would turn with less friction. Worked like a charm.
Thanks for posting.

I'm glad you gave it a try, and thanks for letting me know about the problem with the hole position. I may have to double-check my measurements and edit the instructions.
looking good!
