Admin Post I always find that measuring to get the location to drill the side dots to be a time consuming PITA. Quite a long time ago I made a jig to do this... but I lost it... so I made another one.... New & Improved. It's pretty self-explanitory from the pics. Most guitars I make have a 12" fretboard radius, so I've made this jig with that radius. But I can make a wooden "handle" at any radius and quickly change the jig to accomodate. So the distance from the edge of fretboard to the dot is constant and I just "eyeball" the location between the frets. I can drill all the holes within a minute or so. .
