20 ounce curved radius gutters, closely following the radius of the tower wall.
These large capacity 20 oz. copper curved gutters were built to fit the tower base and turret of this piece of new construction. That makes it sound easy, but it is an impressive technical feat to make them fit snug to the tower wall throughout the entire path of this extended, steady radius arc. Rather than learn to do it yourself, you can go to Concord Sheet Metal of Pittsburg, California and ask them where they got theirs.
