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 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!

knex is an easy building toy that many people have and doesnt require tools to make it
That is correct. If you can imagine it, you can build it!
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?
do u play guild wars or world of war craft
I play guild wars....
guild wars is AWESOME!!
i like wow gameplay better but guild wars is pretty sweet
get a life (on runescape)
Zelda games are the Chuck Norris of all media.
Timesplitters 2 is the god of all first person shooters.
(along with the original Goldeneye)
Its one of those games where you can play for a week and i gets boring like runescape... buy a REAL game like Half-life 2 or GTA IV
dude, you pull the trigger which sends the bolt flying into the unfourunate target
*unfortunate* sorry 'bout that =)

this is a fun crossbow. I really like it. I haven't made the special ammo for it butit works fine if u use a grey rod with agrey cap at the point and an orange double sided at the back. OVERALL:GOOD GUN PS i took the red rod off the bottom of the front. i think it looks a wee bit cooler but watever.
put an orange on the front and it can put a hole in paper thats strectched tight.or sharpen the rod
use 3 grey connectors
