Intro: KNEX CROSSBOW

BEHOLD THE FORRUNNER OF ALL KNEX CROSSBOWS ON THIS SIGHT!!

A simple knex crossbow that uses few pieces. Many different types of ammo and modifications. Includes Flighted Crossbow Bolt simmilar to the sniper round but I did not copy KILLERK! I made it when I was 10.

Length=40 Cm Height 16 Cm

Step 1: Collecting the Materials and Constructing the Crossbow

Materials

Crossbow

Rods
6 green
2 white
4 red
4 blue
2 grey

Connectors
4 yellow
2 orange
6 red
2 white
1 grey
4 light grey
2 green
2 brown

Other
1 medium strengh rubber band
3-5 smaller rubber bands

Follow the steps through the pictures

Step 2: Stringing the Crossbow

Follow the pictures to string the crossbow.

Add extra rubberbands to the trigger if the bow rubberband is too strong.

The trigger rubberbands will counter act the bow rubberbands.


Step 3: Constructing Crossbow Bolt

Dart

Rods
1 red
1 green
Connector
1 orange
1 black socket
1 grey

Other
Paper
Tape

Construct the rod then tape on the paper fletching at both ends and back. The fletching size depends on the power of the crossbow. Keep testing it until it is good.


Step 4: Firing and Loading the Crossbow

Take the rubber band and wrap it around the two green connectors and put in the bolt. Press the trigger and shoot. Range depends on rubberbands and ammo. You can also shoot other ammo types like grey connectors.

This crossbow is only the basic form. You can make it smaller and also make it shoot two bolts at a time.

Problems,
The bolt keeps falling out:
Put some grippy tape in the trigger area.

The Rubber band keeps jamming into the gap between the yellow and green connectors at trigger:
Also use tape, but use smooth tape.

This is my first instructable, tell me if it is good!

    Because K'Nex are easy to build, easy to repair, easy to find, don't take long to make, and are a WHOLE LOT of FUN! They give you a sense of accomplishment when you make one and it works great. A lot more fun than boring old WOOD! lol

    I don't get it. What do you do at the last stage when you wrap the rubber band round the green stuff. Whats supposed to happen? What rubber band do you use and where does it go?
