I found 20 feet of 4 inch pipe in my yard.. what to make?

[pyromanic13]

it's none pressure rated, and I want to do something with it, cannon related or not.

[fatcat]

Matbe if you built a huge chamber you could use it for a barrel.

More practically, you could cut off a 5 or 6 foot length and use it for a guide tube for a coke & mentos rocket

hmmm.... 20 feet of 4 inch piping...Well I wouldn't use it for a chamber definitely....You could cut off a manageable length and make a TP barrel like this

[super spuder]

if i had that much pipe. i would cut it in halfe and make two chambers, join the togather with a T and then put a piston valve on it ,and then go and shoot some spuds

[Flying_Salt]

Use it as a mortar for model rockets?
I'd get a HUGE pressure rated chamber, then use that as the barrel for, tp I guess?

[Bubba05]

I see alot of barrels in you yard dude. get some rated chamers and experament with it!!

Have fun

contend with Schmanman's Swat Gun..... but i doubt you'll win

[schmanman]

build a large cannon

(chaos, 20 feet of four inch has less volume than 10 feet of 6 inch)

[jackssmirkingrevenge]

divide it somewhere along the line (something like
my 3" cannon and make a massive combustion - since you have no idea of what pressure it can handle, I think this would be the safest and cheapest option.

[noname]

Agreed with Jack, just make a 20 foot long combustion cannon. It's the easiest, cheapest, and probably the most fun thing to do with it.

[super spuder]

yea, that sounds like a great idea. then all you have to find is some gineticly modified spuds to shoot out of it . or you could just make your own ammunition, i like the gineticly modified spuds better thou (i wonder if radioactive spuds would glow) (tracer round) any ways. if you do make a 20 foot long combustion i want to see it and if you find any gineticly modified green glowing radioactive spuds to put in it, i want to see thos to

[super spuder]

sorry i got a little off topic

[super spuder]

so back on topic, is this pipe ABS (black) or PVC (white)

[pyromanic13]

pvc, and I don't want to make a cannon out of it. ....small chimney?
