Was a lengthy thread on this exact subject awhile back. Try a search under pipe fencing. I don't remember exactly where it was, but it had many responses.

Good luck on it. S.W.

Search for "pipe fence" and you will find threads on this, a few months ago. Here's one.

when i build fence like this i charge 7.50 a linear foot if you make a jig to hang the rod with it goes much quicker you also have to consider whos digging the the post holes i try to have them dug by the owner before i get there i usually do these alone and can run 100 ft a day sometimes more

setting the post, top railing and hanging rods, im charging 7.50 too. per ft!
