Fixing a Guitar Fretboard: Radius Tools

Video Transcript

"Most fretboards, at one time a fretboard, fretboards were flat. Completely flat across the top. But as guitar players evolved, we've and guitars themselves evolved, fretboards started taking on rounded shapes. This particular one has a radius of twelve inches, approximately. In other words, if there were a circle here, this fretboard would have the roundness of a cylinder that had a twenty-four inch hole. Because the fretboards now are radiused, depending on the brand of insturment, some have radiuses of nine inches. Some have radiuses of twelve inches. Fretboard radiusing tools that you would have to get like these little brass insets, are handy when working on frets because we're going to want to force the fret into the same shape that the fretboard has. And so this tool here, which has the same radius as the neck, can be used to help force these frets into the correct shape so that they sit flat against the fretboard."
