Looks ok. Just paint it to make it look better. Is this your first cannon?

[stevenarroyo]

well this is my first air cannon.

i have made a potato cannon before this 1 long time ago. but i need to fix it my potato cannon is combustion not air powered.

and i also have a smaller air cannon that i made too, after this 1

it has a dwv bell reducer cut that of and get pressure rated parts its not safe with out it

[blind909]

Scrap the bell reducer. And I was wrong about the chamber, disregard what is written below.

It reads: 7200 2" Type 1 SCH 40 ASTM D-2665 NSF-dwv PVC 1120 PR 280 PSI @ 23c ASTM D-1785

looks like it says sch 40 to me

[blind909]

looks like it says sch 40 to me

Sch 40 is just the wall thickness. That means pretty much nothing. What you need to see is SCH 40 NSF-PW, Not DWV

[stevenarroyo]

that chamber is sch40

[Sticky_Tape]

Scrap the whole damn chamber. The Chamber Pipe says NSF-dwv, and so i tthat bell reducer. Click to enlarge the picture, then read the red writing.

It reads: 7200 2" Type 1 SCH 40 ASTM D-2665 NSF-dwv PVC 1120 PR 280 PSI @ 23c ASTM D-1785

It says pr 280psi idiot. Therefore it is ok to use don't listen to blind.

[trollhameran]

well i dont really no what im on about cause i only use copper so you'd be better off listening to the other people

[blind909]

God Damn People, Sch 40 is just a wall thickness. Read all the writing in red on your air chamber.

[Sticky_Tape]

No crap blind but it also says PR 280psi which means it is pressure rated if it has a rating on it it is ok it use.

[blind909]

Ok, but part of it is still DWV, the bell reducer.

[stevenarroyo]

ok, so if the chamber was was 1mm thick and it says it can go to 250psi do u think it's true!!!

i think it's better to have a thicker wall and have it say 200psi then a thin wall saying 500psi

[Sticky_Tape]

Well you said scrap the whole chamber which he doesn't need to do.
