A Trebuchet Story

The Best of Intentions

It all started out with Jeff saying he wanted to build a robot. About an hour later, we had managed to take over an empty bedroom with a table stolen from another room. Then, we retrieved the fischertechnik parts from their 3 year journey in the storage cabinet.

A Dose of Reality

Building a robot apparently takes a little more planning than what we were up to that particular evening. Well, okay, its probably more honest to leave the "that particular evening" clause off. Anyway, after having watch several episodes of Junk Yard Wars that centered on various medieval tools of destruction, it didn't take long to make the decision move on to building a trebuchet.

The Reality of Time

Well, we hadn't planned well enough ahead to have sufficient time to finish the trebuchet that evening. Okay, we hadn't planned. Anyway, we ran out of time. A few days later, when Jeff had left town to see Kirk over Spring Break, Brian happened to be over and once again we were looking for something to do. It didn't take long to find the partially constructed trebuchet. About two hours later, we had mostly redesigned it. And, it worked. Below are the pictures with some brief explanations.

Couch Firing

Trebuchet Fire 01 View From The Target This is the view our fearful opponents would have (were they to be about 6 inches tall). However, as we concluded later, couches may have little to fear from this trebuchet.
Trebuchet Fire 02 Ready Here Brian is making the final adjustments to the sling in preperation for firing.
Trebuchet Fire 03 Release Fractions of a second after the trigger is released, the firing arm is in motion. As you may note, Brian wisely posed for the picture by watching the camera through the entire firing cycle.
Trebuchet Fire 04 In Flight From this angle, you can actually see the hex nut near the top of the image as it wreaks terror into the heart of our unsuspecting target couch.
Trebuchet Fire 05 At Rest After firing upon the couch, the trebuchet comes to rest. The long chain dangling from the firing arm is the sling.
Trebuchet Fire 06 Target Hit With a smirk clearly indicating his satisfaction with our successful siege on the couch, Brian proudly points at the epicenter of our formidable trebuchet's strike against the couch.
