So after all these TUBES WANTED ads I've placed, and all the searching on the net, and discussing it here in the forums, I've still never been given the name of a machine shop I can contact who can just supply custom tubes outright. What's with that!
I'd just like to be able to say, give me a 35" aluminum long tube, 20 TPI threaded for 1/2" on each end, 7" O.D. with walls somewhere from 0.08" to 0.1" thickness. I can't believe there's not 50 vendors who can do it in the USA.
