If I were t try to make a bike trailer from plastic pipe, what sort of pipe would be best?
As a non welder, with limited mechanical skills, I wondered about building a trailer from say, plastic plumbing pipe, having the advantage of L shaped joints for corners and T joints to strut it for strength. Granted, its not going to be as strong as a metal one, and probably not much lighter, but its something for me to work on in my forthcoming man cave/basement....
