Jack, you're right, of course. Use that stuff to pull the 3 phase
through for the big CONTEST amp. Keep it off the towers.
BUT.....
The 4130 Chrome-Moly 2.5" 3/8" wall I'm gonna buy for the big tower is
called TUBING also. "Pipe" is designed to have "stuff" flow inside it,
the name "Tubing" can apply to material used for OTHER mechanical
purposes (like holding up those stack arrays ...) !
Cheers.
