  • How brittle is PVC?

    I'm planning a ghetto mod. I need to know how brittle PVC is at roughly 0 degrees F. I'm thinking of wrapping it with fiberglass for added strength if it's too brittle. I don't want it to break in the cold. It never hits much more than 0' F here anyway.

    I think I'm going to make a roll bar for my pickup. Not for safety, but for looks and to mount a light bar on. I'm thinking I may want to put my hand on it and jump out of the back of my truck without it flexing too much or breaking.

    Since there are no stock roll bars made for my truck since it's so new, and they are way too much money to have custom built. I was thinking about PVC pipe.

    Any thoughts?

    BTW: this would be an intigration as mart of a larger ghetto mod.

      instead of PVC, consider ABS. The black stuff is more vinyle less brittle in the cold.. though, it may 'flex' more than PVC. This may take some investigation.

        Dude, don't do that...have some welding shop make a real one or just wait for a real one to come out (can't imagine it being long)...I would feel really bad putting a PVC "roll bar" on the back of my brand spanking new pickup...

          Yea,
          I've seen PVC roll cages before, and it seems a little too Rice for me... Don't do it... Go all the way with metal, or don't go at all.

            PVC = stronger than ABS, usually less expensive and easier to find
            ABS = Chemically resilliant, Very Lightweight

            I wouldn't recommend either of these materials for what you're doing...unless this larger ghetto mod involves spudgunning
            I hope the mods don't realize I can still post.

              Spudgunnin is the ****
              The hairspray ones are okay, but the pneumatic are the best, imho

                pneumatic ones allow for semi-automatic action.

                if you use the proper ratios and fuels (like butane), then combustion guns can fire just as far.

                    me and a friend built a breech loading system, and we used our knowledge of physics to build an ultra-efficient combustion chamber.

                    right now im working on building a super-accurate spud rifle.

                      i wouldnt recommend doing the roll cage thing with PVC. if you do get into an accident the plastic can snap and hit you.

                      rockthevolvo....lets see some pics
                      I made a "spud" gun back in the day with PVC. It was badass. We used to throw nails n crap in there. we also made one with a smaller size barrel and chamber for shooting pennies. The force was enough to bend the pennies when it hit concrete.
