Step 8: The fret board
I did go out and buy a nice piece of cocobolo for the fretboard. It is a really nice variety of wood and looks really sharp. The spacing for the frets were found with an online fret calculator. You can just search google and find a decent one. Then with a dial caliper and square the individual positions were scribed and cut with a thin saw.
While perusing the home depot I found some hardwood screw caps and used them to make the dots out of. Just drilled a bunch of small holes, glued them in, and sanded them flush. Finally the top of the fret board was rounded with a home made radius sander.
The sander is a pretty simple device. I saw one at a store and decided it was to simple and useful to shell out $35 on, so I just made it on my table saw. Its a pretty simple concept. Take a short length of 2x4 and saw a wide channel. The thickness at the bottom should be about a 1/4" glue some sand paper to the bottom and use some nuts and bolts to expand the top and change the curvature of the bottom. It does a surprisingly good job.
