Knex Catapult

About: I like building stuff and sailing. I also love fishing

first of all ill like to say this isnt my design the guy who buildt it is called ACDC5968. He dosent have a instructables channel but a youtube channel. He makes a lot of catapults and trebuchets. But anyway i didnt think that his instructions were so clear so i made some on instructables.

So you likey sure you do now lets get building!
