I Made a Catapult

One more thing to check off my bucket list, I now have both made and fired a piece of siege weaponry. A trebuchet to be exact. A couple of bed frames, bits of channel stock, a dirt bike chain, freon tank filled with water, an old rim, and some parts from a treadmill. The arm is on a ball bearing pivot and flings things ever so smoothly. The farthest shot thus far is about 60ft, but I'm hoping to improve that with a proper sling and a couple of heavy old batteries for the counterweight as soon as I get some from work. It's still a work in progress, but it's pretty awesome even as it sits now at roughly 12ft tall. Once I get it really tuned up maybe I'll post some videos. You can also see Mighty King Tiki Toki Tookie behind me too.

EDIT: I've vastly improved it with two large truck batteries for a counterweight and a sling instead of a simple hook. It now slings objects about 150ft. Also, BRIGHT GREEN!
