Harv,
Although I have never personally worked with metal, in a previous career "incarnation" (when I was much younger), I spent fifteen years as owner/designer/operator of a design/build business with fine hardwoods as the medium. Most of our work (fifteen full time craftsmen) was custom for restaraunts, offices, churches, designers and homeowners.
Concurrent with five of those years I owned a contemporary furniture/art/crafts gallery representing over 100 artists and employing six designers on staff. My wife is also an accomplished interior designer (1996 Recipient of Southeast Designer of the Year award), so I have a sense of how artists often "skip"-think and certainly appreciate the challenges of custom work.
One of my personal favorite challenges was chair design. When I saw your posted Deere pics, my mind could not help but wander into the what-if metal realm, especially as regards your bending abilities. Mayhaps some one of these days we'll get a chance to get together and talk about the possibilities...
You do nice work and clearly enjoy it. I admire and respect that.
