K'nex Bow Prototype

Introduction: K'nex Bow Prototype

NOTE: Please note before making this that this bow is designed to shoot larger arrows. I haven't tested it yet, so I'm only posting it as an idea that others can build on. After building it please don't fling any criticism for the design. If you have modded it, please post some photos because I want to see it!

Step 1: Supplies

Gather all of the pieces.......

14 red
4 green
12 yellow
4 gray

2 purple (the kind that bends)
2 red
12 yellow
3 blue
4 white
8 small black (not in the picture)

You need four special black pieces. They latch onto the side of rods but don't fit on the ends. They are used to hold the rubber band in place so don't fret if you don't have them.

Step 2: Making the Limbs

Follow what's on the pictures.

You stack the limbs so they are each 6 yellow rods thick.

Step 3: Finishing the Bow and Stringing

Connect the two limbs to the center and it should look like the picture. Then take the two pruple rods and bend them like in the picture. This will make the bow resist to breaking in half. Finally put the two long rubber bands made earlier to make an x shape like the picture.

Step 4: Arrows

As for the arrows part, you're pretty much on your own. I've thought about using real arrows, but the fletching doesn't fit through the hole. You could do it if you cut off the fletching, but I'm not willing to waste a 20$ carbon arrow. Good luck with toying with this bow. Send me any arrow ideas that work!

    I've tried to fit real arrows in there but the fletching blocks the path. You might be able to try it with a special kind called flu-flu fletching. Other than that you may have to resort to making your own wooden arrows or cutting fletching off.
