The fretboard is made of ebony.  It is cut to length, but not tapered.  The fret slots are cut into the fretboard first, and then the fretboard is tapered, and bound with binding to match the body.  Then small dots are inlaid in the binding to mark the fret positions.  They are glued in with cyanoacrilate glue.

The front fret markers are then inlaid, just like all the other inlays.  First the inlays are cut out, and traced onto the fretboard.

Then the cavities are routed with a flexible shaft router in a base.

Finally, the inlays are glued into the fretboard with black cyanoacrilate glue.  When the glue dries, the inlays are sanded flush with the fretboard.  The fretboard is now ready to glue onto the neck.
