Sleeving Pipe

[medievalman]

i am going to make a buzooka style combustion launcher, and i have two ?'s:

what should i sleeve 2in. PVC in?

what should i sleeve 1 1/2in. PVC in?

thanks for you're help.

I don't know what to sleeve 2" in, why would you need to do that? If the 1.5" is SDR 21 it fits perfectly in 2" sch40

[Flying_Salt]

Doesn't 1 1/2'' Sch. 40 have the same OD as 1 1/2'' SDR-21? Just sleeve the 1 1/2'' in some 2'' sch. 80.

You could sleeve both in 3in or higher.

[MisterSteve124]

Why do you want to sleeve them?

[squeaks]

Yeah, your question is really vague as to what you're trying to accomplish.

[medievalman]

alright, im not very good at drwing, but you asked for it!

i am trying to make an inline combustion cannon with a 2in. chamber and a 1 1/2in. barrel, but i want to put it in a larger tube so that it looks like a buzooka or rocket launcher.

here is the diagram:



click on it to get a better picture.

the red is 1 1/2 in. the blue is 2 in. and the purple is what i would sleeve the entire thing in.

ok well i don't know of anything that fits in 2" sch 40 but you could take a slice out of another peice of 2" sch 40 and sleeve that inside it.

[medievalman]

i want something that fits outside 2in. pipe

[frankrede]

2 1/2 sch 80.
Good luck finding it.

[Bluetooth]

You have to order it most likely.

[medievalman]

well, thanks anyway guys. disregard this question. i have gotten the answers i wanted, and i dont think i will be building the gun exactly as i planned, but then again, things dont usually go as planned.

Look at the other 'bazooka' style guns on here and find out how they made it.
