[GSBN] Curved Gutter

[Art Ludwig/ Oasis]

Here's a pic of the short straight segment technique in cut and soldered copper. Old school, pretty and nice for a long service life. Can't see it in this photo, but they peened the whole thing to make it look extra cool, which it definitely did. 

At one point when the copper price crashed it was the same cost as enameled steel I considered using it on our roof instead of steel. I calculated the amount of Cu leaching from a 1600± ft2 of it with 18" a year of rain and concluded that it was fine if it was adsorbing into soil but not if it was going directly into a freshwater aquatic ecosystem. For gutters only it's probably too little Cu to worry about unless you are filling an aquarium. By the time the HOA approved our project--a year later--Cu was 4x as expensive as steel. Glad I didn't use Cu, as it saves us $ on an armed guard to keep an eye on the roof...
