Ok. I've got a lot of advice from you fine folks and I have come up with a working plan that is wide open to suggestions. As I said previously my pipe is oil field 2" schedule 40. It is in 30 foot sections so I figure on cutting it to get 4 posts at 7.5 feet each. It has the liner but I have a fairly effective way of torch cutting it so Im not concerned about the liner. The plan is to cement every 3rd or 4th post and to drive the others into the hard ground. These will have the ends dipped in thick tar where it contacts the ground to prevent premature rusting. I want to space them 8 or 9 feet apart (comments?) and run one top rail of pipe. Should the top rail go on top of the posts, on the inside of the posts, or in between? Below the rail I want to run 3 rows of metal cable with springs at the ends. (saw a fence set up like this and it look pretty slick and was holding back some horses just fine) Does anyone know what gauge cable I should run and how I go about setting this up and are there springs specifically designed for this? Also I have seen it run throught the pipe and also run on the outside of pipe through metal eyes. Which would you prefer? If I do any painting it will be around my welds. My fencing priorities have unfortunatly fell in the order of 1) cost 2) functionality 3) cosmetic apperance. I am very greatful for the help I got on my original post and I am looking forward to more input. I don't want to make any huge mistakes here. Thanks again!
