My birthday is coming up and I decided to get some nut files so I can replace some cheap nuts with bone. After all my research, I've decided to go with the Stew Mac gauged nut files but I'm still a little confused on the sizes to get. This will mostly be for electric with size 10 strings. I was wanting to get 5 files plus a 0.010 gauged saw to start the slots. I also plan to get the string spacing ruler and was wanting opinions on their nut and saddle vise as well. So opinions on which set would work best? 1) 0.013, 0.016, 0.028, 0.035, 0.046 This seems to be the closest to the sizes of a set of 10 strings. 2) 0.016, 0.020, 0.028, 0.042, 0.050 This is a little bigger than a set of 10 strings but I read it is better to go 0.003-0.006 larger for the slots. Can I get away with files from the hardware store to shape the nut or should I also get their nut shaping file set? Thanks for any help. I want to do this right.
