Here's the inlay in process:

The red stuff is a marking fluid. Once it dries, you can scribe a very fine line in it. Mike's now done with the inlay:

and up close:

Here's how it works: you take off the inlay plate with carefully placed mounting screws (nice black one will be here soon for the white side):

And you get to the brass plate:

The screws are angled to get the clearance to mount the master volume control. Then the inlay plate mounts to this brass plate for the decorative finish. You won't need to access this hardly ever, so we didn't think the two-tier plate would be a problem. Hope you like it!
