The plan is to cover the top of the tray with etched brass work. Below is a sketch of the brass peices that will be cut and then etched. The holes in the brass will accommodate some of the brass rod which will drop down the tray and fill in the hollow space below.

I’m thinking I’ll then start running some copper wire between all the rods and between some of the end nuts.

I want this brass work to have a splash of modernity something like a steampunk, vintage electronics looks. I want the etching that will go on this brass to have a circuit-board look. I’ll get to that in a day or two.

In this drawing you can also see the the flat brass spirals and the reinforced base.
