The Big Book of
Catapult and Trebuchet

Catapult, Trebuchet, Mangonel,
Ballista, Onager, Petraria, Scorpion...

They came by many names and many different designs. The hurling machines, the artillery of the ancient world that gave us the modern words Ballistic and Engineer, and laid the earliest foundations for the science we call physics.

For fifteen years we manufactured and sold pre-cut kits of these amazing machines. Millions of dollars worth of happy customers came across our web site during that time, until one day the nefarious forces of international trade and market dynamics compelled us off to other things.

But now you can get the plans and instructions to make your own kits. All our most popular models are collected in this Big Book of Catapult and Trebuchet Plans.

We'll be honest, it's not the most well-written book out there. But we weren't going for style points or artistic awards. If you want plain, raw, un-embellished information, mechanical drawings, photographs and simple tips on how to cut, assemble and fine-tune a hurling machine that will actually work and work well, this is the book for you.
