I bet mine is bigger than yours

This won't be finished for a while, but this is the base of a trebuchet I'm building. 14.5' to the lever axle and when finished it will be 35' tall and have a 1000-2000lb counterweight

The neighbor kids have one almost exactly that size. It hasn't been used in years. Pretty cool contraption all the same.
Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.

That's cool.  I built one about 3 years ago with my students.  Lotta work.  What will you do for a trigger mechanism?

Haven't quite decided yet, but I've been thinking about (hard to describe) a rotating wheel that has two arms coming of it. One will have a slight curve which will fit through an eyelet on the arm and the other longer arm will have a pull string( might rig the end of the string to a board that can be hit with a sledge if it needs to be quicker)

Slip hook, I believe is the term for that sort of release.
Mine is waaay smaller than yours ::)
I made a miniature siege engine way back, had pictures with some pet gerbils 'manning' it... well 'Gerbilling' it I s'pose  :laugh:
Took some stop action pics in a darkened room with a flash linked to the arm of the engine... before digital cameras.
It shows the action of the sling lobbing a marble.
