It's time for an update.
I finished sanding the inlayed fretboard down. Overall I'm very happy with the result. On the board with white MOP blocks, the black dye seems to have penetrated the shell in a couple of areas, most noticeably on the inlay of the 1st fret. While the dye penetration appears uniform and is not a huge issue, I will have to come up with either a different manner of glueing the inlay in, or some way of sealing the shell to prevent this. Interestingly there was no dye penetration of the gold shell. Weird.
Next I turned my attention to the headstock. I glued in a "fretboard" stop, as Benedetto calls it, which is a piece of wood glued at the headstock/fretboard surface intersection to bring the level of the headstock overlay up so that the binding for headstock and fretboard line up. I wasn't able to get it to work exactly, as I would have had to move the fretboard further down the neck, which would have moved the 14th fret past the body join. That goes into the notes for the next two. I didn't get a picture of that.
Next I glued on the headstock overlay. I cut a 17 degree angle into the edge of the headstock so it would make a 90 degree angle to the fretboard surface. I then rough cut the headstock to shape and the attached the headstock template to route it to shape.
I routed it to shape with a top bearing flush trim but when DISASTER STRUCK!
The short grain near on the sharp edges tore out. Fortunate I had off cuts from the headstock that I was able to use to make a patch piece. I cut the headstock surface flat with a fret saw and planed the headstock off cut true.
Overall the repair looks ok, so that's done.
Next I routed the headstock for the binding and for the inlay. I decided to try CA glue and dust instead of the dyed ebony. It seems to work well.
Next I tapered the fretboard. I have a jig that I can use to route straight lines with a flush trim router, which I used to trim each side of the fretboard.
I've been working on a commissioned neck build that is close to wrapping up, so I should be able to get back up to speed in terms of progress.
