an idea to strengthen pvc chambers..

Unread postAuthor: trae08 » Thu Feb 15, 2007 4:08 pm

i dunno if this will work or not it might eat away at the pvc but i was thinkin couldnt you take some fiberglass resin an some clothe and wrap it around your chamber so it will harden an make your chamber stronger..

just an idea i had.

Buying a heavier duty PVC (Such as sch 80 or 120) is cheaper, easier, cleaner, and has undergone quality control. Anything more than this, and steel would be the more economic route.

Personally, I think it's a bad idea, because if the pipe DOES fail, the fiberglass will create shrapnel.

For a combustion gun, ABS is the preferred material IMO. If it does fail, it rips clean open down a sidewall of the pipe, and depressurizes with very little if any fragments. PVC, if it fails (or if it's dropped) will shatter into lots of pieces. Plastic doesn't show up on X-rays either.

For pneumatic guns, I wouldn't use any "coating" or "shielding" on the chamber, except maybe a layer of thick fabric or leather secured by hose clamps or zip ties - that would help contain shrapnel. For a combustion, I wouldn't worry about it at all. If you're honestly worried, go up to sch80 or 120 PVC as BC suggested.

Peace,
Pete Zaria.

What do you think, seeing as they are both PLASTIC pipe. Almost nothing except for metal shows up on X-rays.

Bones show up on x-rays. And other non-metallic stuff. It all depends on the size of the constituent molecules nuclei really.

I know that bones show up on X-rays, and why, you don't need to explain. Did I say nothing except for metals? No.

So, I'm not arguing with you here, but have you had experience with getting an x-ray with shards of PVC in you? Cause if so i bet that sucks.

I haven't, but my friend got a piece of shrapnel in his leg, luckily he could just pull it out, without going to the hospital or anything.

He was at my house shooting one of my pneumatic paintball guns. I told him to use it maximum 80 psi, he decided to put it to 140. It was between his legs because he was muzzle loading a paintball, when it exploded. There was a huge BLAM that left our ears ringing for 20 minutes, and shrapnel went everywhere, including into his leg. It only went about half an inch in, but it still had to hurt.
I got pissed off at him and made him buy me new parts. :lol:

NEVER TRUST THE PRESSURE RATINGS ON PVC!!!
The 3/4" Sch 40 was rated to 480, but do you really think it can take that much? I use my launchers at 90 psi max, as a safety measure (except for my inline vortex gun, because the only parts under pressure are the blowgun and quick conect).

Helooooooooo, is there no such thing as moderation around here?
It's been discussed before, it's just a stupid myth, PVC DOES show up on x-rays. And even if it didn't, we have more advanced non-invasive scanning technology nowadays anyway (MRI, ultrasound).
This topic belongs in Material Discussion anyway.
