  • can u post the dimensions?

  • It's been a while since I built it. 16 or 17" high, maybe 22 long, 8 3/4 wide. Arm is 15 inches on the long side and 5 on the short side. Various counterweights 10 to 20 lbs, 15 most commonly used. Axle was a short length of 1/2" EMT, maybe10 inches. It took a lot of work to get it shooting right; started at 35 feet, so that was doubled with better tuning.

  • how would you sell it to me for?

  • Twenty-five bucks without the weights, you pick it up. Los Angeles, CA.

  • Yes. The tennis ball is normal-sized; the trebuchet is tiny. 15 inches from the ground to the axle.
