Floating arm Trebuchet

This summer I plan on building a floating arm Trebuchet (FAT) for pumpkin chunkin. We ran a contest this fall, and this year I will run it and win it. I have been making sketches and figuring. These are my latest with what I think will work
Seems like it should work, but we will mess around with it and see what happens. I expect many failures before getting it right. It will be fun throwing things around the backyard no matter how bad it turns out.
I will continue posting about this

Pumpkin Chunkin

I have been spending the past month getting ready for our first Pumpkin Chunkin contest. Lots of details to deal with. Last few nights have been tough falling to sleep. Hard to think of what I am missing or forgetting, but am sure there are plenty of things. Hoping for a good turnout, but hard to say. Hope for good weather too.
We are holding it at a pumpkin farm near here. It should be lots of fun. If we have enough teams

Electrical is an issue, might have to use a car as a generator to run the PA system. I have a generator, but the amount of noise it makes, makes it useless for the PA.
