Good progress today. I enlarged the PG screw holes and countersank them. Same with the control plate, except I left them a slight bit shallow so when it's back from polishing, they can be cleaned up with the countersink.
I made room in the pickup rout for the neck pickup screws with a 1/2" Forstner bit. Then I routed for the bridge pickup.
That done, all the pieces went back together to make sure everything fits.
I'm not sure I like the big gap around the bridge pickup. I do have a chrome cover with the center open but that will probably affect tone. I'd like a black cover anyway. I do have a black plastic one but it won't fit on the pickup. The bridge pickup may or may not get a cover but it'll depend on my mood when I start the wiring. I might cut a piece of black pickguard material to put under the plate to hide the gap.
The 1" knobs look a bit small so I ordered some 1.3" ones to try. Those will be here in a week or so.
