First, go to the Grey company web page. They are a bunch of catapult enthusiasts. As for me, my Scouts had to build a catapult for a Viking themed Klondike a few years ago. ( yes, I know that they did not have them, but I was willing to go along with it.) Anyway, after a few experiments, I came up with a perrier type. It has no counterweight, but other than that, it is similar to a trebuchet. The proportion I used for the beam was to divide the beam up into 5 parts, then have it balance on the last division line. The thing looked awful, and the kids would not believe it would work, until they used it to launch a volly ball over 60 yards.
