Picture of 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

Picture of 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)

Sypran (author)  buthead1875 years ago
oops lol well ty for telling
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...
