It would be nice if there were an economical source of this rod mat'l
avail w/o hacking up cleaning rods, and it has many other great uses.
My chimney rod sections are only abt 3/8" or less and I don't think I'd
use that for a dodger. A set of chimney rods isn't exactly a retail
giveaway, either, and one is stuck with the unusable couplings as well
as the rather short lengths. 316L tubing in modest sizes is fairly
easy and forgiving to bend in a conduit bender (not the Harry Homeowner
type). One may even practice a little with scrap conduit to gain
confidence. I'd get the right tubing & sidle up to a commercial
electrician on a jobsite at lunchtime. At lot of these guys feel
under-appreciated & they might even bend it all up for you for free if
you've already lain it out. Remember to pickle/passivate after
finished working it all up prior covering. Unless SS is not available
in one's area, it seems a false economy to invest the planning, time,
fabric & work for a lesser mat'l.
