I have always made necks and fret boards out of maple. Finishing was always easy - you glue the pieces together, shape the contours spray the finish and slap the frets on and you have a finished neck!
For my latest project I am going to stick with the maple neck, but I am going to go with a ebony fret board.
Of the top of my head I have a few finishing/construction options:
1. Finish the neck first. Then glue the shaped fret board (which would be previously dyed black) on the neck then glue them both together. Then slap the frets on.
2. Or probably better. Glue both pieces together then shape the fret board. Then dye the fret board black (I want it perfectly black). Then tape off the fret board and spray the nitro on the neck. The remove the masking and slap the frets on.
Any advice would be greatly appreciated.
