Ok this is my first instructable, it is a cross bow with a new bow system (at this curent time) i hope u like it.

Ok for this pic you can see it has no trigger, that's because in not good at makeing trigers, well for crossbows anyway...

I don't know the range of it for i use weak rbs do to all my good 1s r ether :under something, destroyed by my cat, or put somewhere without me knowing... Ok anyway i used 2 hairbands on the limbs and they work really good, for me it fires 30ft before it hits something (this is with my ammo that i made, last step shows the ammo and how to make it)

Step 1: The Stock Pt 1

this is rather easy

7 blue rods
9 yellow conecters
1 grey connecter

(note that the blue behind the yellow is in middle connection thing not the hole except the 1 near my hand thats in the diagonal 1)

Step 2: Back Wheel

the back wheel is not important, (the wheel its self everything else I think is)

5 orange conectors
2 red rods
2 gray conectors
1 small wheel
1 blue rod


Step 3: The Crossbow Limbs

ok this is the crossbow limbs, of course you goto build 2

12 white/silver rods
4 white conectors
8 orange conectors
2 grey conectors
2 green/black rods

Step 4: The Top

OK this is going to be the top for the crossbow/ balista

14 grey connectors
1 yellow rod
4 yellow conectors
1 red rod
1 black idk what to call but its half connector half rod
2 green/ black rods

Step 5: Botten of the Bow Part

the bottom of this bow

1 yellow rod
5 yellow conectors
1 red rod
10 grey conectors
2 green/ black rods
2 half rod half connector things

Step 6: The Conection Point of Stock

this will be later used to connect the bow part to the ending stock

2 yellow rods
4 green/black rods
4 blue circle things
4 yellow connectors

Step 7: Peices Ull Need Later

ya these you will need a bit later.

Step 8: Step 1+2 Conected

simple connection between step 1 and 2 you'll do on both sides

Step 9: Step 6+ Step 8

OK there is 4 added pieces the wheel is on the other side

2 yellow con
2 green/blk rods

Step 10: Add to Top and Botem and Mix

its a small addition to the top part of the bow
*plz note the 2 yellow connectors in the back are not supposed be in this pic1*

pic 2 is how the bottom should look

pic 3 is when u add limb then mix

pic 4 is just the top and bottem mixed

also note that after you are done add a red piece like in pic 3 unless you want the bow to break constantly

pic 4 is that 4 orange conectors and 2 green rods u built a wile back connected to the middle red rod

Step 11: Stock Con to Bow

ok now you will start some conections from the stock to the bow itself (yay finaly)

pic 1 this thing will keep the stock straight if some weight is put on it

pic 2 this is the first conections between the bow and the stock

pic 3 the top red peice realy dose not need the half rod peice but its there in case 1 falls off and i cant find it i have spares, then there is the yellow conector with 2 green rods on bolth sides

pic 4 this is optional, you can also take a red rod and put normal small wheels in this place to

Step 12: Stringing for Power

ok now this will show you my sugestions for stringing it

pic 1: the bowstring should be a stretchy not the strongest of all rubber band

pic 2: this is were i used hairbands but try to use semi string bands here also note the band in the wheel of the limb that should be a strong band

pic 3: also you can put the rubber bands like this to keep the bow from bending down

Step 13: My Kind of Arrow

ok you are done with the bow now what? easy you make arrows!

basicly what this is is a 10 inch wooded skewer with a notch on the end and tape for feathers and tape neer the tip to add some weight on the front so it gose head down first

you might want to skip the notch for it is kind of hard but it dose not mater

ok to load it (srry dont hove a pic) you place the arrow inbetween the limb wheels and pull back all you can before the end of the orange conectors going inbetween

ty for reading this, this was brought to you by: sypran, 5 times internet not responding, 2 computer shutdowns, 3 cans of seltzer, my old cellphone and 1 crossbow

Can you believe these photos were taken by a cellphone?

again its a y clip
ok idk y but it wont show my pic on step 10 so gust foloow what i said there
u may not believe me but i made up "idk" lol
just to let u know u did so NOT make up idk
i did cus one day i was sayin "i dont know to people on msn" and i got lazy of sayin it like that so i made it idk!
stop making up stuff
dude seriously i made it up!i created idk
i seriously think i made up tyvm (thank you very much)
Maybe you did for Instructables, but I heard it first like 15 years ago.
i heard idk before i had an instructables account and before i found this website
yeah right that has been around for a long time.LOL
I'm gullible, I'll believe you.
lol
oh, yeah?!? well I made lol LOL, NOT
i highly doubt that but whatever
you need bettr pictures
I probably do, these are old and from my old cellphone...
i found tht its good to but another piece of a skewer on the back for the notch<br />
&nbsp;is there a trigger
sadly no... I did make one once but it hardly worked and was to sensitive <br />
that thing you said you dont know what to call are called y clips just so u know
lol you forgot the 1 blue rod<br />
oops lol well ty for telling<br />
I built this and I launch the long gray or black rod probably 50 feet!
now to make one of these that's twice the size of IAC's heavy cannon, switch to spears for ammo, and TAKE OVER THE WORLD! or at least the block i live on...
lol, I wanted to do something like that for my schools science club, but it had to be a catapult, no ballistas alowed
Dude this has been one of the most strongest knex guns i hav ever made man u need to give urself a big pat on the back when i shot it the ammo put a hole in my wall and is still stuck in there
I added a crude trigger to mine so I could hold it and fire it.
HOW DO YOU LOAD AND FIRE????
umm you take the bolt out it through the front. hold the ruberband and the bolt, oull back then realese...
man you need some better pictures
i know.. ill update soon, (this was all taken from my cheap cellphone cammera) ill update it before the 27th
thanks
sorry that i could not update, i did not realise that i was going away from home for vacation. as soon as i can get my hands on some knex (i hope my uncle still has some) ill get pictures
thats fine i can wait
nice,but actualy it's not a crossbow but a ballista
yeah
