A High-Powered K'Nex crossbow that can reach a pretty long distance depending on how many rubber bands you put on it. Its made entirely out of K'Nex and Rubber Bands

Step 1: Make the Rubber Band Holder.

This part is critical, so follow the instructions carefully

Step 2: Make the Body of the Crossbow

This piece is not so critical but is still needed

Step 3: Make the Trigger System

This part is a little tricky but is very important - without it the crossbow is hard to load and shoot

Step 4: Make the Handle

This part is not really all that important, but it does make it easier to hold the crossbow

Step 5: Put the Handle and Trigger System Together

Click the Handle and trigger system together using the two white rods and the two yellow connectors

Step 6: Attatch the Handle/trigger to the Body

enter longer description for this step

Step 7: Attatch the Body/trigger/handle to the Bow

Put the the body/trigger/handle on the bow by connecting the yellow rods to the yellow connectors and the green rods to the yellow connectors.

Step 8: Add Rubber Bands

Add the rubber bands between the two red connectors (I added sello-tape to improve performance)

Step 9: Add Counter Rubber Bands

Add the counter rubber bands on the white and blue rods to make the trigger work - These rubber bands must overpower the other rubber bands for the trigger to work

Step 10: Add a Trigger

Add an orange piece to the trigger system to make it easier to use

Step 11: Bow Complete!

The bow is now complete, But don't go Yet, you need to make the bolts that it fires see the next step to make a bolt

Step 12: Make a Bolt

Make this bolt (if you don't have the weird bit at the tip you can use a grey connector instead, or just don't have a tip)

Step 13: Fire the Crossbow

Pull back the Rubber bands and place them in the slot on the yellow connectors

Step 14: Put the Bolt In

Put the bolt in the crossbow so that the orange connector on the bolt is sitting so the rubber bands are inside the end of it

Step 15: Pull the Trigger!

Pull back the orange connector piece made in step 10! - but Be careful where you shoot it
Pretty cool, although the handle bends a little.

Very Good I Modded it very rapidly and its is more bigger longer and bullet is changed to have a red conneter on the end to make it more realistic, <br>also i have mended it so more rubberband's can be added.
Anyone made a good looking pistol that fires? Most look kinda rubbish
Anyone made a good looking pistol that fires? Most look kinda rubbish
its good for its size but it isnt powerful unless you want to risk breaking parts <br>
good crossbow. have a cookie
the only thing wrong with this crossbow is that if you use enough elastic bands and make it strong enough without to much that makes the grew long bits snap is that the actualy neck could brake so iv made a modded version hope u like it havent started a structional for it yet tho so heres a pic. sorry about the pic on its side<br>
i have done a similar modification and found out that more than 3 rubber bands with bend and snap the gray rods so i modified on with a scope, iron sights, and ended up with longer bow and better handle
I modded and post my modded verison . Ye there is a special thanks to you ^^
this works pretty good, are the bands suposed to get caught on those orange pieces?
The orange pieces on the Bolts, yes.
<em>Coming soon:</em><br/><br/><strong>D-17</strong><br/>

spam on your own instructable =P<br/>
omg that thing is awsome 10/10
My sidearm looks like yours, but mine is much smaller, and of course simpler, but it has a VERY RELIABLE MAG that does NOT jam. Do you need pics? or not? (Oh yes extreme builder told me that it must fire larger ammo, so I am modding it now)
is there a parts list?
k so it's next year, which isn't soon. What's the holdup?
god freaking tap-dancing christ (lol) post it!!! it looks so cool :( (getting annoyed)
Ummmmmm you confuze me...
lol im getting angry cause its taking so long
Yeah well it's obviously not going to be posted.
I made it, it jams like heck.
Yea The new version has some improvments which stop it from jaming And guys, Ill post when I get some time between studying and Playing Gmod :D
Are you actually going to post it? You posted that picture like... 2 years ago.
That stinx
Yeah. It looks awesome though.
ahh shite!! it looks so damn good maybe i can make my own version always think positive
I don't even care LoL.
What is that? A air soft gun??
hmm, its that any good? It looks like i could build it from the pics. but not easily so i want to know if it is worth spending the time looking at the pics.
I made it :-)
is it any good?
's ok, Im going to try to upgrade it though, The ram goes way past where it needs to, so Im going to try moving it back and a couple of other things.
Can you please post this, I have been waiting and it looks like some others have been too.
