Had a bit of a breakthrough today on one of the problems with the dials. I originally wanted the dials to be 3d printed, but the resolution was just too fine for shapeways. I stumbled on a method of making your own electronics PCB's with black spray paint and a laser engraver. I figured I would give it a shot on 360 yellow brass, and see what happened.
Not sure if this is THE solution, but it certainly looks good. I'll try 3d printing the dials with out the engravings, and see if I can duplicate the results I got on the flat brass with some actual 3d printed dials. Also have to see how well acid black and red soaks into the engravings to give the correct contrast.
Here is the black for contrast
