After wibbling around for ages, I finally started building a trebuchet.
This is a small portable trebuchet. The design brief was to be crude, unrealistic, and to fold up small enough to fit into my car. The beam is 2m long, the frame dismantles into 3 pieces, each 54" long and it's all powered by a 12 brick counterweight.
Ammunition was a mix of water balloons and half bricks. Maximum range on the first trial was a rather disappointing 30 yards or so, so enhancements are already planned - maybe a 20 brick counterweight.

So far this is our biggest trebuchet, but we're already planning the next...
