Getting into the meat of the fabrication now. Mostly a pretty straight-forward process and totally familiar to those of you who've followed along with other projects here on my blog. One hallmark of this particular design is the complication of using two different metals. Corten and stainless both rely on an oxide layer that develops on their surface to provide corrosion protection; Corten's oxide just happens to be, well, rust-colored, while stainless steel's is chalky gray. The only issue this presents is the rusty Corten oxide can stain the stainless (how the?), ruining the aesthetics of the piece. I elected to use internal supports (standoffs) to hold the two materials a quarter inch apart to prevent this.
