I made four rain chains sometime in the mid 00s. the first was was for myself. I wanted everything to be copper, so I made all of the bolts and nuts out of copper grounding wire.the catch basin on the bottom is the housing from the original 1923 porch light from my house, and the funnel up top was my attempt at metal spinning. I went with a more complicated two-loop chain. I made a jig to fishmouth the ends of the loop wire so I could solder the links. I still have the jig in my workshop in case I ever decide to make more.
This is the chain today.
