I am guessing that it would be best to cover a steel frame with copper sheeting rather than build them entirely out of copper, is that right? What gauge/weight of copper should we use? I have access to a heavy duty shear and brake at work, and My wife has a real knack for soldering. I know copper sheeting is expensive, but the prices quoted to us by fabricators are crazy, we are pretty handy at woodworking and at working with steel , is this a job we should tackle?

Lots of choices, John.
I'm going to post one topper that is:
a) fun to make
b) unusual
c) good for "high" winds. (this one lasted through one breeze at 122mph, clocked on wind gauge before gauge quit. (Platinum, AK)
d) old Norwegian design
