Shaping The Fretboard
Once the slots have been cut, the fretboard is placed on a fretboard taper – this is basically a piece of shaped plywood cut to a particular taper and can be used for a variety of instruments from guitars to basses.
How do we use it? We start with our nut and slide it up the tapered template until the ends of the nut are flush with the sides of the taper template – we are using a nut width of 43mm so our fretboard starts at the point where the taper is 43mm wide.
We mark 4.5mm which is the depth of the nut and draw a line across – this is where our fretboard (fret 0 if you like) starts. We match up the centre line of the fretboard with the centre line on the template and stick it down carefully using NEC tape.
Once this is ready, we can turn the material over and see the overhang on each side – this is extra wood which we need to remove so we return to the bandsaw to remove the bulk of the excess:
And then a router for the rest:
