▪ Most repair people know that on a fretboard with a tight radius the upper frets have to be milled flatter than the first frets if the player wants to bend strings without “fret-out.” Most just file several times until the get the results they are after. What they are really doing is trying to turn the playing surface into a conical section. Mottola’s method is more precise. Consider it the thinking man’s way to dress frets for the most optimum action. With 7 figures, 6 photos, and a chart.
