| I bought my dad a desktop trebuchet for Christmas. It's pretty good actually, you get some plasticine with it that's sort of rock-coloured which the trebuchet can sling from one side of the room to the other.
I suppose if we were to build one nowadays the easiest thing to use would be steel box section. Just quickly weld it together and robert's your father's brother. I seem to remember they did that on scrapheap challenge a year or two ago to fling a mini down a runway, but the whole thing imploded just as it was about to fire. It was quality.

Probably so, I was trying to balance performance with ease of construction. As long as it's properly braced and strongly welded steel should be OK. Unless you're Airbus making a huge lump of high-quality carbon fibre is going to be a royal pain in the arse.
How about a sexier metal, like titanium?
