Fretboard Prep with a Radius Sanding Block

This bass is in the shop for a full refret. All the old frets have been carefully removed from the rosewood fretboard.

In this short clip, I am using a Radius Sanding Block [9.5"] and sandpaper to ensure that before installing new frets: (i) the fretboard is level throughout its length, (ii) any dings or low spots have been eliminated, and (iii) the fretboard has a consistent radius of 9.5" throughout its length. This procedure is known as "prepping" the fretboard, and is a critical initial step towards achieving a fret job your customers will love. Video Credit: Norisah Siran.
