I have built a table-top Trebuchet. It measures about 20"x20"x16".
I made it out of 1"x2" pine. Used a transformer from an old cash register for the ballast. The sling was cut from an old pair of denim jeans.
While it's not a boulder hurling beast it will launch a marble over 50 feet. I will post pictures if you want.
Currently the welding professor has it to draw up plans to construct one entirely of steel. Tried to explain some weight/stress problems he will run into but he just wants to have a project for the students to work on other than just running beads on blocks.
