Medium trebuchet a success

We had our first public launch with our new medium trebuchet. It actually worked, repeatedly! I have some serious doubts that it would hold together after repeated launches. We do have one or two things to modify but nothing serious, a washer here, a cable there. I have to admit that I am already designing a new medium trebuchet for just such an occasion. I want one that is easily assembled by one person. I think I have that part figured out, now I want to come up with a way to launch and re-launch quickly with one person. I am planning on working on this over the winter and spring. I want to make it a more robust machine and not give to much worry to distance. It's for pubic launching and the public is still awed but 100 ft, not just 150ft. That's something that I forget.
