I guess no one has tried to dye a white bone nut. I found a black TUSQ nut at Musicians' Friend that I hope I can modify to fit.

Next questions: The neck has a little play when fitted into the pocket. How do I set it in the right position, leading straight out? Next, what is the best way to fill the small spaces between neck and body? Third, I have stained and TruOiled a little too much of the neck heel. How much do I have to do to rough it up so the glue will take?
