The Trebuchet/cataput

I'm surprised I managed to spell trebuchet right without spell check - although it is still complaining, I checked with Google and it is the right spelling. Now I look at it again, I think it's a catapult. Not sure which it is, but it took a while to make (enjoyed the challenge) and works very nicely! It can fire about 5 - 7 meters, not bad for a small model.
