anyone want to give me some pointers .... how do you cut the holes and install fretboard markers, dots, in a new fretboard? ... a brad point bit in a drill press is what I was thinking about...I can do all the locating and depth control alright... just wondering about what kind of cutting tool to use for making the holes. Also, what are the sizes of the dots on a 70's D 18? They seem to be 5, 6 and 7 mm ... but the middle one looks more like 1/4" 6.35mm ... I can get a 5,6 and 7mm drill bit but not 6.35mm bit... any words of wisdom / experience will be greatly appreciated... and Thank you for this great Forum.
