Let’s face it, nobody needs a medieval siege weapon on their desk. Or do they? I recently decided that the lack of catapults in our brainstorming sessions at work was negatively impacting our ability to be creative. So I decided to remedy this. My friend Bill Gurstelle is the dean of siege weapons, so I chose to build a modified version of the Roman onager-style catapult from his book The Art of the Catapult. Using only pine, twine, pegs, glue, and a re-purposed night-stand drawer pull, I was able to build a great looking, fun, and functional desktop catapult.
