We will show you how to build an extremely simple and durable fiberglass bow that can be scaled to any strength. Although it definitely isnt for target shooting it is well worth the $5. Warning this is dangerous and should not be used for any illicit activity. We claim no responsibility for injury or damage caused by this.

Step 1: Assemble and prepare your materials

For this instructable you will need:
-Several fiberglass reflector poles(people put them at the edge of their lawns)
-400 lb test twine (army navy stores have it)
-hot glue gun
-and arrows, or 1/4" wooden dowels to make arrows from

First you have to remove the reflectors from the fiber glass rods, if they are those red plastic ones simply smash them on the ground. remove any plastic remnants till you have only the bare rod left.

Step 2: Binding the fiberglass rods

Now is where you get to choose the ultimate strength of the bow. The more fiber glass you use, the stronger the bow is. At the same time this increases the complexity of binding the rods together. In my case i wanted an extremly light simple bow so i took 3 rods, tacked them together with hot glueand started wrapping them with the twine. The best way to join them well is to put a long bead of hot down each joint between the rods and wrap the twine around uniformly while the glue is still hot. This lets it permeate the windings and soak into the twine creating a strong but flexible fiber glass, Nylon and hot glue composite material. Continue wrapping the whole length of the rod to ensure that there are no weak points.

why is this under nerf? this isn't a nerf thing

if i didn't have a twine what string can i use

you could use an old fishing rod for the fiberglass
not really a fishing rod is tappered and hollow the can't be either

What diameter rods did you use? Also, are these hollow rods or solid?

its from a fiberglass reflector pole look here look in the pic, its the one with the red reflector on it. Srry i cant describe it better

This would make a nice weekend project for Scouts. I would recommend you use some of your nylon string to create a grip at the center of the bow. Just use a series of half-hitches until the grip is wide enough and then secure the loose end with your hot glue. You can also use a bit of duct tape on your quarter-inch dowel to make the fletching - the feathers - for the arrows. Squeeze three pieces of the duct tape equidistance around the end so it contacts the dowel and the sticky side of each piece of the tape and then trim the tape to the right shape.

Neat! Awesome job, and I will be careful. ;-)
