Seige Engines - For when you absolutely, positively, have to hurl a pumpkin!
Since my teens I've been interested in the history, the construction, and the mechanical physics of siege engines of all sorts. I've built many working models of varying scales and even a few reasonably large engines of destruction over the years. I can't begin to describe the buzz from sending a pumpkin or watermelon sub-orbital. Here's a few pics of various engines I've either created, or helped others create, have a chuckle :-)
