Looking good, Doc. Thanks for making me glad I don't build necks! For me it would be easier to just refinish the entire neck after filing the fret ends.
I have it pretty easy with nuts also since I only do P or J necks. I just superglue a properly cut one to a blank and duplicate it with the belt sander, Norman nut files and needle files for the slots and clean up with a flat file, etc. I've roughed out as many as 3 bone nuts at a time (superglue and a machinist vise).
