In my repair business I often have occasion to make nuts. Sometimes if a customer requests I will make one using the Tusq blanks. When doing fender necks it would be useful and time saving to use the pre slotted nuts as they seem to line up well most of the time. I have used the pre-slotted ones with a radiused nut slot since they fit well after removing the little block they preform for flat bottomed slots. I was wondering if any of my repairment brethern have used these for a flatbottomed slot. It seems to me to leave only three points of contact and a lot of air under the nut. I'm thinking this is a poor design. I'm trying to come up with a quick way to fill that space and still make the nut useable. Maybe epoxy or super glue with some kind of filler or tiny little rosewood or maple wedges. It just struck me as a poor design. Any opinions?
