Click on the step 8 to see how this bow is nearly indestructible from rubberband force.

This is a knex bow that I made that looks very futuristic. It uses a lot of pieces and is pretty big for a bow. It measures over 2 1/2 feet tall. The grip is very comfortable, but I made it to fit my hands. You may need to change the grip around if your hand is bigger. If it's smaller, it won't make much of a difference.

Also, this bow was made for right handers, so if you're left hand, all you have to do is turn it around and hold it the opposite way. IF you are right handed, the way to hold this bow is have the yellow connector slots sticking towards your right hand and hold it with your left hand. I'll show a picture of how to hold it.

BTW, this is my first knex weapon that isn't a gun. It's very sturdy and can hold a lot of pressure. I do not know how powerful it is right now, but I'm pretty sure it will at least be able to shoot 15 - 20 feet. I'll make an arrow step after I have found a rubberband big enough to fit with the bow.

I am canadian, what rubberbands did you use for your cannon? Those look very stretchy.

Finally, a part list. I make a part list for most of my creations so that the builder doesn't find out that he/she doesn't have enough pieces on the second to last step. lol.

Step 1: The Limbs: the Bottom Half

We will be making the limbs. The limbs are sturdy and can hold a lot of pressure. It will be broken into two steps: The Bottom Half and The Top Half.

1: This is the finished product. We will be making two of these.
2: This is the bottom half of the limb. Make two of these.
3: The bottom half of the limb again. This time, you're looking at the underside.

Step 2: The Limbs: the Top Half & Connection

This is the top half of the limbs that we will be making.

1: This is the top half of the limb. The wheel turns to reduce the bending in the limbs and keeping them from breaking. Make two of these.
2: This is the underside of the limb. In this picture, the way the wheel is set up, the wheel will not turn. Instead, make the orange connectors going straight out instead of slanted upwards.
3: In case you were having trouble, this is how the wheel connects. Once again, put the orange connectors facing out instead of slanted upwards.
4: Get the top half and the bottom half of one of the limbs. It is easier to connect while looking at the underside.
5: Connect. Do steps 4 and 5 again with the other two pieces.

Step 3: The Limb and Handle Dividers

Here are two bars that divide the handle from the limbs.

1: Make two of these.
2: The underside.

Step 4: The Handle

The handle was designed to fit my hand. You may need to modify it slightly to fit yours.

1: The handle complete. Ignore the stuff in the background.
2: The handle complete (cont.) Ignore the junk in the background (and my hand lol). The two light grey connectors that you see were not supposed to be there.
3: Make two of these.
4: Step 3 (cont.)
5: Step 3 and 4 (cont.)
6: A support rod.
7: The grip area. It doesn't look very comfortable, but it actually is.
8: Connect.
9: Connect (cont.)
10: Connect the support rod.

Step 5: The Two Main Support Bars

These are the two main support bars. You may need to stretch the rod a little to connect, but it keeps it very sturdy.

1: The two main support bars. (OMG, my knee!)
2: zoom in
3: zoom in (again). Make note that at the end of one connector, there are three reds, while there are only 2 red connectors and a blue spacer on the other end.
4: Showing the blue spacer that i just talked about.

Step 6: Connection! WHOO!

1: Connect one of the dividers to the bottom half of one of the limbs. The two red rods that come out of the divider go half way in between the two yellow connectors so that it is even.
2: Connect the handle to the divider.
3: Step 2 (cont.)
4: Connect the divider and the second limb to the other side of the handle.
5: Connect the main rods to bow.
6: Step 5 (cont.) You want to connect the red connectors here.
7: This is how you connect.
8: zoom out. (OMG, Nerf gun and some yarn!)

Step 7: Mods 1: Strength

These mods are very important! This mod provides strength.

1: Attach a bendy rod to a yellow connector.
2: Attach it to the limb like so. Do it to the other side of the limb. Then repeat this step on the second limb.
3: Get this bendy rod. It does not have to be a different color.
4: attach it here....
5: ... and here. Do not repeat on the other side. Do repeat on the second limb.
6: Get this piece. Make two.
7: Connect here...
8: ... and here. Repeat on the opposite direction.

Step 8: Mod 2: Protection

I first want to say that this has never been done before in the history of knex bows or crossbows. This is a limb modifier that tilts upwards when you've pulled back the rubberband and tilts downwards when the rubberband is in place. It prevents any stress on the limb, therefore making the limb nearly indestructible.

1: First, change the wheel part so that it looks like this. Everything should be straight.
2: Normal.
3: Tilted up.
