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

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

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

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

that chamber is sch40

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

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

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

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.

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

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

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