I am making a license plate / sign guitar with the sign being 12"X 9" celebrating the Irish heritage of a friend. The bridge I am using came from Gitty. My mind took a vacation and I spaced the string indentions too wide (3/8") at the nut for the spacing of the Gitty bridge (which is 7/16"). The outer strings are almost even with the width the fret board. What would be the string spacings that would work on a 1 1/2"wide bone nut? Thanks in advance for your help!
Depends on your fingers. Mine are stubby, so I use 5/16".
I go at it the other way, set your outermost strings then divvy up the remainder. Once that is in the bag, figuring bridge spacing is a straight compare job. Yeah the spacings vary a little but since I bulk precut necks anyhow, it seems to work out OK
