Copper is my metal of preference. Unfinished it won't rust (tarnish yes, rust no). When lightly polished to a mid-level shine, copper has a certain refined brillance that you don't get from cold chrome and that you can't afford to get from gold.
(Don't remove all its tarnish though; highly polished its hue is too "pink.)Especially in an outdoor rustic enviornment, copper's orange-brown glow just seems right
Not only does copper have sophisticated ornamental qualities, it has a nice balance between workability and durability and it's readily available.
Copper raw goods, are easily mined at your local "Har-Whar" store (disguised as common household plumbing) ...Sorry Keweenaw http://www.exploringthenorth.com/ghost/towns.htmlThe previous copper rant was made possible through a grant by....The Semi-Precious Metals Speculative Investment Group of America and ....the generous donations of your local Pipefitters Union...and readers like you.
....Not really...Sorry, a PBS moment snuck in...
The threaded fitting shown in the middle below was introduced in the first Instructable. The next few steps here detail the cleat-like point on the working end (right) and the finial topper with storage (left).
