This guy has some very good information on set-ups, guitar builds, and why/who/what kinds of questions. He has a few opinions I disagree with, but that's fine. Here's one about "How to keep a six screw Strat whammy from going out of tune" (My opinion - throw it in the dumpster! It'll never go out of tune again...) :toothy12:

But right towards the beginning of this one he talks about sizing yer nut's grooves, and (astonishing!) he mentions that you can wrap SANDPAPER over something, size it comparatively with your cheap calipers, and cut a wider groove. I usually use a little shop rule or wrap it right around a NUT FILE - they have these neat-o things called handles. The cheap calipers are good for all sorts of things, when you don't need to know what it measures but it just has to be this big. For me I'd throw in the Optivisors or some sort of magnification, you really can learn to look at the string, look at the groove, and say "hmmm."
