Replying to Need to Build Portable Rail

Hey there fellow NS'rs

So I'm looking to build a somewhat portable pvc/abs rail or preferable large diameter pvc/abs pipe to jib this season in the backyard...first of all if any of you know where I can get a large diameter pvc like 8 to 10 inches any info would be great. But other than that once I find a piece I want to build a small portable stand for the rail/jib. Any input as to how best do this would be greatly appreciated! +k for being legit

Thanks
Josh
