How to… crown and polish frets

by claesgellerbrink

Last week I got all the parts needed to try to refret my Tokai, Since I have never done any form of fret work before I thought it was a good idea to practice on some guitars before I got down to business on my beloved Les Paul. The first thing did was to crown and polish the frets on my EKO Ranger VI. It was a bit scary, like always when you do things for the first time, but I soon realised that it wasn’t harder than anything else I done in the past.

I masked the fretboard and then crowned the frets with my Uo-Chikyu medium fret crowning file. I read that was good to use 400, 600 and 1200 grit sandpaper to polish the frets but I could only find 400 and 800 here in Barcelona. Either way, it felt like the main difference was made by the last step, the wire wool.

Once the frets was shiny on smooth from the wire wool I went over them one last time with a cloth and some metal polish and the removed the masking tape and oiled up the fretboard with lemon oil. I decided to change the machine heads as well, I had a set of open back grover copies that seemed to suit fine. I think the neck almost looks like new now.
