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!



how do i get a pic thing?
u have one! : )
he posted that a year ago
and you replied a year after
now it is a year later i will reply
Whoops. You saw nothing. Got it?
now i reply a year after AGAIN
i don't quite understand. What is the appeal of these knex weapons? why not create a wonderful weapon out of somthing other than plastic? im working on a nice scale crossbow instructable made of wood that is 1m by 1m completed
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.<br>(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 =) <br/>
Where are the 2 red rods going to on the trigger?
hate to say it but its NOT the first cross bow on this site a crossbow was posted in november and this in december. link to the real first crossbow: <a href="https://www.instructables.com/id/Knex-Cross-Bow/" rel="nofollow">https://www.instructables.com/id/Knex-Cross-Bow/</a>
5stars cause its a first
actually its the 2nd
im 10. i made a pistol sized crossbow and it shoots 50 ft with 2 bands.
The instructions for the trigger aren't clear enough.&nbsp; PLEASE&nbsp;TAKE&nbsp;SOME&nbsp;MORE&nbsp;PICS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<br /> &gt;:-(<br />
Dude, you need 3 grey rods on the firing track.
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
Im going to make a sub-compact CAR submachine gun from this model ( dont worry I will put Hobo lord in my credits)
this isnt really so much as a crossbow ... its kind of like a pistol bow....... any ways nice job 4/5 because its sooooo easy
so this was the 1st crossbow! looks good
plz will someone make a small wrist crossbow iv wanted 1 for a while now but no ones made 1 and i have no clue how grrrrr so plz can you make 1 mr hobo lordon?

thats not a very good website
extremely primitive bow, but it works xd
i added a stabilazer using 2 reds rods awhite rod and a blue snap connector
OK
takes the instruct out of instructable
If you want to shoot smaller ammo, it works better if the bottom of the barrel is a row of orange connectors instead of the gray rod. It gets rids of the bumps between the gray rod and the connectors.
The last stage is when you put the rubberbands over the green nobs, it will not release but may move a bit forward, then you load a bolt and click the trigger.
It has a little lack in instructions for making the parts but i think everyone here could manage to build this.
no its pretty darn hard to follow especially as there is no instructions just please if you can post instructions! oh btw i managed to make it with difficulty
It shoots 50-75 feet with the new bolt.
you want authentic, I have one right now and it is more powerful than the first but it bends grey pieces. Ill get the picture soon
Authentic! It's very cool as it doesn't utilize the traditional "barrel" as it uses a track. Very unique design! Could you make a second-generation version that looks even more like a crossbow with the rubber band attached to the top? You could also strengthen it to allow stronger rubber bands.
not bad its cool seeing all the different designs of weapons people make out of knex
