Holy crap! Called the local steel place and they want $166 for 24' of 1.75x.188 DOM. Fock that noise. Pipe sounds much better lol.
If I was doing it, I would build the halo, and top main bars out of 1.75 .120, (6 points) that attach to the frame, then the rest out of the supports, seat bars, guessets and cross bracing out of a mix of 1.75 .090 and 1.5
