Thanks boobhah. It is at Floating Arm Trebuchet Plans Download
There are 4 pages that detail the construction and also a google sketchup download right under the graphic of the trebuchet so people can get the dimensions. After we finish checking out other people's stuff we were thinking about making another set of plans where the center wheel is closer to the drop as we are finding that the design seems to be moving towards brutal drops by moving the center wheel closer to the top and using shorter arms.
My son did the design and built most of it. I was just there to offer advice for construction and to make sure he still had all his fingers after using the tablesaw and router.
