BIG NASTY

[ADAM GILLIAM]

I built a pneumatic cannon I call "BIG NASTY".It's about 12' long,the barrel is 10' long 3" sch40 pvc.It can shoot 20 oz coke bottles frozen about 500 yards.At 20 yards it can shoot a frozen or thawed coke bottle on its side through 3 sheets of 5/8" plywood.At 10 yards it can shoot a 20 oz coke bottle on its side through 4 sheets of 5/8" plywood. I used 3" irrigation valves and 3072 cubic inches of air at 120 psi.

Oh really lets see some pictures. Or has your camera broken?

[killagorrila99]

C'mon, Dont post here untill you have pictures. Its unessisary (Spellcheck needed) and makes us wonder if you have even built the gun.

Oh and:

I used 3" irrigation valves and 3072 cubic inches of air for propellant.

Propelent??? If its a pneumatic you Need air, Not propelent.

[schmanman]

show us, dont tell us.

[SpudStuff]

Some how I don't believe him. I wonder why.
What Size Chamber?
Huh
huh
huh
See you don't know. BUT I DO!

[SpudStuff]

Too bad EVERY part on that chamber is DVW.

[killagorrila99]

DAMB, I love the pics.
How do you know its not pressure rated DWV? We can get that in australia. Nice gun, was it your first?

[SpudStuff]

Thoes are sanitary Tees and elbows and the cross and cleanouts are also sanitary DVW

Who cares? It's still a fricken beast with a good paintjob.

[WOW!!]

Who cares? It's still a fricken beast with a good paintjob.

DWV DWV DWV who cares? I do casue I dont him to kill himself! Yea the cannon is super cool and it is powerfull as hell. but it is still DWV. and the paint job is sweet too.

[noname]

If he doesn't use too high of pressures he's fine.

[SpudStuff]

Yes the sprinkler valves are rated to 200 PSI that is probably what he thinks is the max

[sgort87]

All you dickheads shut up. You were an ass to him before he put up pictures, and after he put up the pictues. He has just posted one of the most powerful guns I have ever seen and you have done nothing but bring him down. I haven't seen anything remotely good from ANY of you. So shut the fuck up. All of you.

As for Adam, VERY sweet job man. I see you went as far as using cam locks and you rigged up a sweet pilot sytem. Great find on those huge valves. Though you did use DWV fittings which aren't intended for this pressure, I assure you that it is fine. I have never had that problem. Just don't use DWV for making piston assemblies.

Once again, incredible job there dude. And welcome to the forums! Very welcome.

[saladtossser]

those fittings actually makes it look better, makes it look so curvy

appreciate the curves guys

[iamthewalrus]

curves are good, especially on girls. but anyway. SWEET CANNON, i love how u took time to paint it and paint it right, and i love the trailer, wheels always help. there are so many red straps and they look friggen awsome with the paint job. nice job man, i give u my approval and i say u is not a noob now.
