Copper Chimney Caps
Hello all, this is my first question(s).
Last summer we built a wood burning pizza oven with an 8x8 clay flue and a big outdoor fireplace with a 12X16 clay flue. We would like to make copper caps for them. We live in a high wind area. 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 Norwegian exhaust stack.jpg

I put a cut clay flue liner on mine . I did however use copper for my water heater flue and the built in grill . minimum that I would use is 16oz.

Pictures
These are not great pictures, they are all I have on my phone currently.
The pizza oven has since had another flue section added, and bee wrapped in brick up to 4" from the top. 20210821_102134 (1).jpg 20210712_064116.jpg

Tools Available
These are the brake and shear from work, my neighbor who is a third generation eavestrough installer has various beading machines and is a whiz at soldering too. While he mostly does modern extruded trough, he also does the copper trough on prestige homes and at the nearby pioneer village.

One town over from me is Sea Cliff where many houses are built on a cliff overlooking Hempstead Harbor. Many of the residents have switched to rotary style caps because they have problems with extreme winds blowing out furnaces and hot water heaters. I’m told they are the answer to high wind problems https://www.youtube.com/watch?v=4hJW4Yry_R4 . Worth considering anyway. ~ John Buchtenkirch
