Build a Fiber Glass Bow for $5 Extremely Simple Cheap and Scalable

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.

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.

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.

After the glue cools, use a knife to make notches on the top and bottom of the bow. Take a length of twine and add loops at both ends. Now afix one loop over the bottom of the bow and push down beding it so you can get the other loop over the top. Wear safety goggles and watch that there are no sharp edges that can spring back and hit you in the face.

Try pulling back on bow a few times and listen for excessive creaking or cracking noises. DO NOT DRY FIRE the bow, firing without an arrow can wreck any bow and is dangerous. Now find the center of the bow by balancing it on your finger and add a spot of hot glue. Shape it into a mound that the arrow can rest easily on without falling. Add a drop of glue at the same level on the bow string so that you can rest the arrow knock on it. Now you can try test firing it, good luck and be careful.
