Allright, here is my dilema....I've rebuilt, re-radiused, and refretted..( with stainless steel ) 4 guitars for a customer...Floyd Roses, locking nuts...String hight at the 12th fret on the high E a little over 1/64th..no buzz...Hight at the low E 1/32nd...( he's finally realized you can't go lower with a 42 for a low E string...)..He's super happy with everything except the spacing at the nut..He wants both E strings to be in 5/32nds in from the sides of the nut..This makes my compensated spacing ruler useless..So I've done the spacing with a caliper..First nuts on them were O.K. except he decided he wanted the 5/32nds from the edges..O.K., no problem, I'll cut new ones gratis..The spacing on 2 of them was a tad off , so I said I'll redo them..I got the spacing between the strings equal within about 5 thousands either way..Still not happy...How can one get anymore accurate than that?..I've been in this buisness for 2 decades and can't remember the last time someone complained about spacing..Is he being unreasonable? I have given him a great package deal on all 4, and allways bend over backwards to keep a customer happy...I've spent as much time doing the nuts on all 4 of these as I spend refretting one regular guitar.P.S. new nuts were not part of the initial deal, but I threw them in for 20 bucks each..Anyone got ideas on how to get them perfect?
