Update:
The new Fender LSR Nut came in the mail today so I went to work installing it on the maple neck, I managed to do a better job of it than I did last time, and the overall result looks a lot better than before, the nut is fitting more snugly in the slot, this time round I didn't strip the head on one of the mounting screws like I did the last time.....
Okay, so with the original tuners and vintage style bridge the guitar seems to be a bit more stable in tuning, some of the strings still go out but I'm blaming that mostly on the original tuners which have some backlash and are probably wearing-out, and the string tree, so, I'm going all-out and getting rid of anything which could be causing the strings to go out of tune, I've ordered a Bladerunner bridge from Super Vee.com, basically the Bladerunner bridge is similar to traditional-style Strat bridges except that it pivots on a small thin piece of spring steel, this eliminates friction where the traditional Strat-Bridge pivots against 6 screws, the result is that the Bladerunner Bridge returns much better to the neutral position where the spring-tension balances out the string tension, I also ordered a set of Fender Locking tuners from Amazon.com to replace the original tuners, incidentally, I'm actually starting to really like Locking Tuners and the whole concept behind them, firstly they make re-stringing your guitar quicker since you don't need to have many winds around the capstan, secondly because you don't need to wind the string that eliminates one of the other causes of tuning instability, when you wind a string around the tuning capstan,bring it up to pitch, and then use the Trem bar, the windings loosen when the string tension drops and then tighten when the string tension goes back up, during this loosening and tightening of the windings, they shift positions on the tuning capstan with the result that sometimes the string will come back to pitch either sharp or flat, this is aggravated by any friction in the slots cut in the nut, and also any backlash in the tuners, Locking Tuners usually exhibit zero, or near zero backlash when new....
