Routing out the back of the neck
After about 8 passes, the back is roughed out.
The fretboard is slotted by hand. The scale is 33-1/4" and there are no steel templates made for this scale. I drew up a scale in CADD, printed it, and adhered it to the ebony stock. Twenty-one (21) fret slots will be cut.
Once all the slots are cut, it's time to remove the paper template.
The fretboard radius will be 10" so I needed to make a router jig. First step is using a circle jig to make the 10" radius in 3/4" MDF.
With both sides shaped, I made the top and drilled a hole for the router bit to fit through.
The 10" radius jig completed.
View from the bottom. The black on the curved sections is ebony dust.
The radius jig at work. The jig slides back and forth along the base to shape the 10" radius
Another shot of the jig at the end of the base.
After the radius jig has done its thing, the fretboard is sanded smooth with a 10" radius sanding block.
