After adjusting the neck's curvature, the strings rub the first frets, so I'll make a custom nut for this Gibson Lucille. A great deal of experience is required to do this job; just taking out the old nut in this kind of Gibson is difficult enough, unlike in some Fenders.
I glue the new bone nut with cyanocrylate, then I polish all the frets and clean the fretboard with a homemade oil blend made in my workshop. I'll adjust the new strings, the distance between them, and the distance to the fretboard. Tune the instrument and play!!!
