Keeping it simple and painting the core black. Wrap and glue thin copper wire in the grooves and adhere to the textured black base. A small control box to be added on the base.
It didn't happen that way and I am still tweaking its design. I have painted the cork screw copper and drilled two small holes on the bottom of the rod. I was planning on adding two small stands here, but after I gave it a try and it all seemed too flimsy. The center piece needs a bit of touch-up where I used aluminum paint. An equipment box needs to fabricated and "attached" to the base of the screw.
