Competition Day

The competition went pretty good. We got first in distance but lacked acurracy a little. Timmothy puller came in 2nd behind us in distance. But we still have a few more people to go.

Final Fabrication

I'm currently working with a partner to make the final trebuchet. We are going with the design of a steel and aluminum base and frame. But our throwing arm is part of a tree branch. As you can see from the pictures here we are cutting down the tree branch to size and melting lead as the counter-weight.
