Hazcon,
i got it BAD this year.... YES its close now.. less than 18 hours to go for light.
hey i should be a SORE member.. i designed and made a tennis ball launcher out of PVC, DUBBED the MOAL 250, for Mother Of All Launchers and the 2.50 is the diameter in inches they are. we also made a barrel for it to shoot 1" superballs with...
we made it with a 12" long by 3" diameter pvc, with an inlet fitting like a bicycle tire and a guage, and a pop-off valve for added saftey... YES i can put 125psi into that canister and with the touch of my blow-gun trigger and teh 3/4" sprinkler valve (modified of course) i can shoot a tennis ball at an astounding 171 FPS (feet per second) thats about 200 yards shot with a tennsi ball!

, although that PAILS in comparison to that of the superball barrel...

yeah we chrono'd the superball as moving at a whoping 551 fps! [&:] WHOA.. we were like uhhh we shouldnt shoot those anymore...
it hit a brick wall, and liquified! it was superball jelly!
i will try to get some pictures of my friend and I execising his dog with the MOAL 250! and it was like only 75$ to make! (compressor not included.)
