I built some ones catapult that shot marbles but i have made it to shoot knex wheels, i have also added a firing mechanism on it .

I give credit to the original catapult's owner

funniest thing I ever flung with it was a bit of turkey burger at my mum


i will post when i get positive comments

it need's a lot of modification

it's the best i could do with limited suply of knex
Can you make instructions for it please?
Urm sorry, I doubt I could. I'm planning to get rid of my k'nex and this was ages ago so I wouldn't even know where to begin. By all means try and build it from these images.
cool
