What's the Plan, Stan?

1. Clean off as much of the old glue as possible, including down the back of the fretboard.
2. Glue the fretboard back to the lower part of the neck.
3. Glue the upper neck onto the lower neck and fretboard.
4. Make some clever jigs!
5. Rout out one side of the neck across the joint; form new sapele infill and glue in place.
6. Once dry, repeat for the other side.
7. Rough shape the side infills to the profile of the neck.
8. Rout out back face of the neck across the joint; form new sapele infill and glue in place.
9. Rough shape the back and sides of the neck.
10. Finish shaping and sand down with progressively finer sandpaper for refinishing (including removing any remaining nasty brown stain that was done on the old repair).
11. Refinish using either satin water based varnish or tung oil. This might be a temporary refinish and I might come back later and do the whole neck, depending on how it turns out. (See previous Yamaha repair https://beaterguitar.blogspot.com/2015/07/ .)
