I would just go buy some pipe at Menards or home depot.It is pretty common stuff. The ends of your poles should just pull out. If you bent the curved poles just bring your new pipe to a metal shop with your old ones.
Our tradition is that of the first man who sneaked away to the creek when the tribe did not really need fish. ~ Roderick Haig-Brown, about modern fishing, A River Never Sleeps, 1946
