OK, for a college project, I want to build a scale model of De Vinci's Trebuchet, or at least something based on it, but I am having a hell of a time pulling up an image of the sketches, I just keep getting pictures of normal trebuchets and that damn hobby kit that has the arm mounted to the side of the mast.  I'm looking for the original sketches.  Is there a PDF of the Codex Atlanticus available (for free)?  Or alternatively can anyone find images of the trebuchet sketches?  I have already assembled (from a kit) a catapult that I will use as my plan B, but I really want to go for the how factor as this is (part of) my final project.

Use particle board, it's just as good as solid wood planks for a fraction of the cost.

Nvm...
