This week I was able to finish sanding my guitar body and also sanding my fretboard. While sanding my fretboard I used a 12 inch radius block sander, which is used to give the fretboard a curve. The sander is curved as if it was a little chunk taken out of a big circle with a radius of 12 inches to make the curve precise. I learned that the gaps under the frets can be filled with the rosewood sawdust to make it look like there is no gap at all.
