Good to see someone making an effort, and the idea is a good one, but there's room for improvement. With that sort of timber, it shouldn't be necessary to help the shot along by throwing it by hand. Just a suggestion - shorten the distance between the upright posts, make the base of the siege engine narrower, and lose the supports under the crossbar, they serve no function and you gain nothing from that kind of support underneath. Move the crossbar to behind the uprights, the connection between the crossbar and the uprights is weak, putting the crossbar behind the uprights will eliminate that. When we're talking torsion artillery the greatest force exerted on the machine is on the base as the sinew/rope/whatever is tightened. Don't drill holes in the uprights, it'll only weaken the construction, place your power source behind your uprights, and make sure it's supported by really beefy wood. Lastly, use 4-5 times more "elastic" as you power source, and replace the floorboard used as a throwing arm, with something of a more suitable shape, a flat face and a curved or triangular back of the arm is what you should go for, it is slightly heavier but much, much stronger. Also, shorten it down to where the basket just clears the crossbar, a long floppy throwing arm isn't what you want on something like this. And yes, I have built siege engines before.

Sick build, more work than I might put into any class projects. Give him props for me!
