what i did was get like a big beam of wood, then buy one 10 ft pvc rail and cut it in 2 and nail each side to the edge, this way you only need one pipe and it works just as well or better then just full pipes because the nails hold it better. a pvc rail is like 7 bucks where i live.
I agree, PVC sucks. It's too slippery so it's nothing like metal, you can't build anything cool with it because it comes in 12ft lenghts and can't be welded, seriously people, just borrow someone's welder and weld your own.
yea pvc is cheap, and if u beat up a rail or something, you can replace easily. I would go with that, but i am building a rail made of metal this year.
