Trebuchets

In high school my friends and I built two trebuchets and established the New Ulm Trebuchet Society (or NUTS). We started the initial product in January and in the spring added wheels to our creation. After launching pumpkins for several hours at our neighbors house for an October festival our first trebuchet fell apart and died. The next year we got together to build a bigger and better trebuchet and again launched pumpkins at the festival. After a year or two of disuse, both trebuchets were dismantled and parts were burned.

Below is our collection of photos, 90 in all. They document all parts of our process, in a rough order of events. Clicking on a thumbnail will take you to the flickr page for the image.
