Ok im going to build a rail for winter. Ive found an about 7' square pipe with the suport bars and all that and its about 2' high. Its a little rusted on the top so I need something to put on top so it will slide but i dont have a welder to weld anything on top but i do have a torch. Anyone have any ideas post them and if u have your own plan post it here to...I might have some photos later. thx
