Lets just anwser all of your questions:

then why the ---- do you guys put so many bends into your headers? -lol. you going to make a straight manifold with 4 or more seperate runners joining? :1

you don't know ---- about potato guns. -ok

not compaired to me.-your god.

you guys dont even use PRESSURE RATED PARTS with your '200psi' pneumatic guns. there is no downside to the U-bend. saves hauling around a 5 foot long hunk of ---- vs a 3ft long more compact launcher. -all PVC is pressure rated. its clearly marked on the side of the PVC piping. :1 all of my guns could easily be put in a car, and move about the car.

and stop talking about pipe sizes that don't exist. if you can't read the size on the pipe, then you shouldn't even bother building one. WTF are you talking about?

and how is 200psi 'less dangerous' than 40? hm?-if you stand at the end of the barral then its dangerous. reguardless if you use an explosive or compressed air. a 2" pipe can hold well over 200psi. if I remeber correctly (its been a few years since ive built a potato gun) a 2" pipe is safety rated to 175psi. thats what the govt. regulates it at. 200psi can be put in there.

and the clicks? you're too retarded to realize that if hairspray was a good fuel, we would use it in our cars. -WTF are you talking about? hairspray as fuel for cars :1

why do we use propane/gas/diesel? it's efficient. it doesn't gum ---- up. with compressed air you wont have any of these problems. i.e. why I mentioned 'maint. free'

and i bet you used dwv fittings in your gun to begin with, and a ball valve for actuation. PVC worked perfectly. home depot. the ***** white. has a PSI safety stamp right on the ----.

and by the way, sch40 fittings aren't rated over 150psi. again, what are you talking about

so when your solvent weld breaks, with your drainage fitting, i'm going to laugh. in the 25-30 guns I built, I never had one fail.

noobs -im quite the newbie. How old are you? I think I was 16-17years old when I built potato guns. I would expect you to be about the same age.

Haha, I love that clip. Haven't seen it in a while

Just because im curious I pulled up McMaster-carr's website and checked 2" PVC pressure rating: (so I was off by about 35psi. it will hold 200psi )

yet on the spudtech website it states PVC is not pressure tested. I cant imagine how ------ retarded that guy is. Its clearly marked on the side of the pipe what its tested to. Pipe is white, the print is blue. Cant miss it.

edit: I rest my case

And you obviously know ---- all about potato guns, c0mpl3x you obviously have a complex, a god or inferiority complex(one of em) I noticed in your other post.

I stated in that other thread you should not recommend using pvc for this. Yeah people do it and it works, but pvc creaps and eventually fails.
When it fails it fractures into shrapnel much like a pipe bomb that you're holding next to your face.
That is fluid pressure rating dumb ***. You can't run compressed air in pvc, you need to use poly ethelyne. When it fails it is ductile, as in it getts a little bubble that pops and safely vents the pressure. Ever see a natural gas line run out of pvc?

Get off your high horse and realize you know ----

*Not saying pe is safe for this ----, but safer than pvc [\disclaimer]
