Sypran's knex ballista

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)

I built this and I launch the long gray or black rod probably 50 feet!

[mettaurlover]

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...

[Sypran]

lol, I wanted to do something like that for my schools science club, but it had to be a catapult, no ballistas alowed

[10110010R]

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

[Pbyrd]

I added a crude trigger to mine so I could hold it and fire it.

[DrWeird117]
