After much planning, a fair amount of dinero, and countless man-hours of work...
I've made a trebuchet. (Which isn't in Firefox's default language pack, shame.)
Don't know what it is? It's pronounced "Treh" "Bu" "Shay", and is a medieval siege weapon.
Here is what it looked like under construction:
Here it is set up. Horrible picture quality, the picture was pink before it was edited.
12 feet long throwing arm, the arm is at it's peak apprx. 16 feet in the air. The weight box weighs 300 of it's maximum 700 lbs, excluding the weight of the weight box it's self. (Approximately 74.5 lbs.)
Unfortunately, the sling requires fine tuning, as the current setup only launches soccer balls partially filled with water... about 30 feet at a constant negative slope. Adjusting sling release time is... annoying to say the least.
Just wanted to show off
Post questions about specs and whatnot... I'm to lazy to list everything and I'll just edit the following spoiler with answers to questions when I've got the time / can find the paper with the detailed specs. The ratio of the length of the arm is fully adjustable, meaning it has the capability to be optimized when I've got enough money and spare time to chuck pumpkins.
