just curious about pricing... i probebly will not buy a rail because i could make them... but what are rail sites? i cant find any that sell rails or boxes.
I got my buddy to weld me a 16 ft 3ft tall flat bar. Seem like a pretty good price cuase he put out like 120 bucks for steel and stick/gas for his welders.
find a cheap pipe bender that can put that large of a radius in a flat bar. My uncle has a shop that does structural steel and the machines arent cheap
