Introduction: KNEX HEAVY CROSSBOW

A upgrade of the original crossbow. More powerful,accurate, and long ranged. Also includes two shotgun barrels on the bottom.

Step 1: Collecting the Materials

Connectors

11 red
19 yellow
10 green
4 light grey
24 grey
4 white
5 orange
2 brown
4 black nobs
4 blue spaces

Rods
8 grey
2 black
6 red
4 yellow
23 green
7 white
5 blue

Rubberbands
1 strong long rubberband (I got one at staples)
5-7 rubberbands for the trigger
2 thick rubberbands

Step 2: Constructing the Main Crossbow Frame

First you must construct the main frame of the crossbow.

1.Construct the trigger area shown below.
2.The construct the front of the gun.
3 construct the firing track.

Step 3: Adding the Accesories and Modifications

The new mods are the new stock, bow,shotgun barrels, and reiforced firing track.

Construct the m through the pictures below.

Step 4: Adding the Rubberbands

Add the trigger rubberbands, bow rubberband, and shot gun barrel rubberbands. The trigger lock is incorporated to the trigger rubberbands.

Add the rubberbands through the pictures below.

Step 5: Loading and Firing

To fire the primary projectiles, pull the rubberband back and over the two green rods and load a bolt and pull the trigger.( find instructions for making the bolt on the KNEX CROSSBOW instructables.)

To fire the secondary fire, pull back the pins and load green or white rods into the barrels.Pinch the two orange connectors together. Press both at the same time for a double shot or just one for two single shot.

you're nerf gun shoot into cardboard at 25 feet (white tiger v2 rifle) and I'm not bleeding from a stupid cheap made in china foam dart going at 7 feet per second. good guns like my m2 and some others can fire at 80+ and 25 feet< god, i've been aroud for a while here and when I here"25 feet" I'm not exatly like "omg!! that's amazing!" and, you don't make nerf guns. you buy them at that stupid little walmart. Last time i checed that's the place the sold a guy a bike and then the quick realese fell off and the wheels where untrue?if you want to argue more, come over to my house you will use your nerf guns and I'll use my knex guns. I'm not paying for your insurance.

If you still think this build the reaper. It shoots 200 ft and travels at over 75 mph. Try to beat that with a nerf gun.

author
xiao hawk (author)g123453892007-07-21

I just toyed with my Knex for about an hour... and I've run into quite a lot of problems. Anyone have a good magazine design that holds around 4-10 yellow or red rods?

(Note to all those that have no clue what a chinese repeating crossbow (Chu ko nu) is, go to this like:
