Lunch break gave me the time to sit down and do some "precision" work: filing and cutting string slots in the smaller neck's nut.
I found a scrap piece of nut material and had glued it into a slot I cut in the "ukulele" peghead. Once it was dry, I filed the height, and used the nut files to cut the slots for the strings. Slots were cut in the nut evenly spaced. The nut files are smooth on the wide part and have the cutting edge only on the sides. My favorite ukulele (Blackie) wanted to watch. Since I'm using a zero fret, the purpose of the nut is only to align the string to the correct left/right position - it doesn't need to be set to the correct height. The strings actually sit on the zero fret, which determines the string height.
