This looks awesome! Did you get a good response from the people who saw it?

Re: pic: Shooting a pvc projectile from 70 yards out at Homecoming!

Looks like a 1.5" dia. barrel. What on earth are you using as a projectile?? (Please don't tell me it was some sort of rodent, because that would just be too wacky)

Rock on!

I've got plans to make one of these somewhere, but I'll probably never get around to it because football isn't well attended at our school.

Going by how full the bleachers are, it seems it is not well attended there either yet they are doing it.

Never give up hope. Maybe your contraption will not only make a name for yourself/your team but also bring people to the football games as well.

Mmm fun times. I have had many adventures with spudguns. I have never made a purely pneumatic though as i have no air compressor. I am currently working on a propane/MAPP/acyteline powered fuel injected cannon.

Talking Re: pic: Shooting a pvc projectile from 70 yards out at Homecoming!

heheh...i have a 2.5-inch-diameter barrel on my air cannon. It uses 120psi per shot. Also, i made an ice mold using leftover PVC from the barrel, so i have a projectile that fits exactly into the barrel and has almost zero friction as it's launched. My cannon can make that shot from 150 yards, and destroy almost twice as much stuff when it lands.
=D
That's me holding the cannon in my picture.

Heres all I have to say..."The artillery is on the way! Onward team onward!" and "3...2...1...Happy New Year *boom *boom!" now maybe those are odd hints on what Col. Abney has up his sleeve but you all will be amazed! These guys are making him raise the level of his guns....keep postin 'em, Maybe FIRST will make Air Cannons legal sometime!, and not " a hazard", as I believe they are referred to now.

Re: pic: Shooting a pvc projectile from 70 yards out at Homecoming!

Psh, I saw a kicker put one through the uprights from 75 yards this weekend

PS. You made an 80 yard shot, not 70. The endzone is 10 yards deep.

Re: pic: Shooting a pvc projectile from 70 yards out at Homecoming!

I think I can answer everyones questions. We just made a ABS , 4 inch, tank with two endcaps. In one side we put in a threaded coupler connected to a ball valve, which had another threaded coupler that mated to the 1 1/2 inch grey pipe. We only used 60-70 psi. The projectile was a smaller pvc tube , 8 inches long, with two end caps that fit pretty close to the inside diameter of the grey pipe. Inside the projectile we weighted the front end with some bolts and stuffed the back end with foam. It was front heavy. This kept it going straight through the air.
I guess we did shoot 80 yards, forgot the endzone! We could have used more psi and shot farther, but alas no time to practice before the one shot we were allowed.
The stands are full! At least for Football at our school.

The whole trick with the air gun is to get the pressurized air out past the valve as fast as possible, only then does the gun work well. A quick wrist is essential!

No one mentioned how we got the picture! It was pure luck! We tried a dozen times earlier during the day and got not a one.
