The guitar is not only fun to learn and play, but also a challenging and rewarding instrument to repair and modify. A guitar's inlay can be modified in a number of ways, and small inlay pieces like side dot fret markers can be replaced without expert training. With the right tools and technique, you can install your own side dot fret markers in a few steps.
Find the exact centre of the fret you want to add a marker to with a ruler. Mark the centre point on the side of the neck with a grease pencil.
Cut the recess for the side dot fret marker with a rotary tool using a 1/16-inch bit.
Place the side dot fret marker in the recess to judge the fit. It should fit as snugly as possible.
Remove the side dot fret marker from the recess.
Smooth any rough edges of the recess with the rotary, hobby knife and small chisel.
Fill the recess with cyanoacrylate (CA) glue.
Place the side dot fret marker in the recess. Allow the glue to dry fully according to the product's instructions before continuing.
Level the side dot fret marker and glue with a sanding block using 320 grit sandpaper.
