Why didn't you go full brass on the decatrons, instead of mixing stainless and copper? Same goes for the counter box: you only wrapped 2 sides when you pro'lly could have wrapped the whole thing in brass... you probably saved yourself 10 hours by not doing that, but you're already in for what, 30 hours already?
Now I'm going to nitpick. :) My only critique is the high gloss finish on the wood looks unfinished in the final assembly picture: you can see drips/wrinkles, and the grain wasn't filled which isn't a good match with high gloss, or if unfilled a hand-oiled finish would not have called attention. This is a consequence of working with mahogany. (And what's with the hand filed-gouges in the cutouts. Yes they are hidden, but details count, man!)
I'm also jealous you have a machine shop. Very jealous.
Super job!
