cool Marlin !!
after you get all that copper polished up, wash it with a solvent
and spray it with clear rattle can finish. stand them vertical while
spraying and drying and you won't see any runs.
(1/2" pipe is plenty strong enough for a few pots and pans).
I remember looking through Pinterest for pot hangers
awhile back and remember seeing the copper pipe hangers.
here are a couple of examples. if you go to the Box Store, you can get
some 3/16" electrical grounding copper wire that is easy to shape by a simple jig
and you won't need any hefty tools or vice. you buy it off the roll by the foot.
for more examples, google: "copper pipe pot hanger"
(you can still use the galvanized pipe and couplings, just spray it with copper paint).
