Your friend must get hit alot then.Mac/pistol man wrote:Are you kidding me? PVC weighs nothing... Expecially if it is above your COG. Like, In real airsoft, one of my friends has a 45 lb vest full of gear... So, PVC would be nothing...frankrede wrote:3" sch-40 would be safe up to 150 by my safety standards.Mac/pistol man wrote:3" couldn't be compressed very high, unless you used schedule 120! Aha!! You could order some schedule 120 pvc, in like 3" that could be pressurized to roughly 440 psi.
Here is a schedule 120 pressure chart from Harvel pvc.
So, if you want to make a backpack out of pvc, use schedule 80 or 120, not schedule 40. Personally, I would use 120, but it is expensive..
It would hold alot more air than 2".
and wtf?
sch 120 would weigh so much on your back.
40 would be bad enough, especially in a airsoft type game
and weight on a vest isn't the same as weight on your back.
sch 80 pvc is about twice the thickness of sch 40.
So that means it will weigh twice as much.
Why use sch 80 when sch 40 will work fine
