I googled solar flux and it would have been a great way to go on this project.
I had no knowledge of it till now, but I've been away from that part of the pipe trades for awhile.
Yes, it was quite a bit more work than brazing a emt frame together.
As you probably know that stainless draws worse than about anything.
I tried my best to pre camber everything and out guess how much it would pull.
Even at that, it is not totally straight.
The good news is it did not twist and has a nice gentle even arc from starboard to port.
Kind of like a cambered bridge beam.
Thanks for the kind words
