I'm going to experiment on some scrap I'm putting decals on today. I need to drill the holes for the bridge and tail piece. The best I could calculate - locating the bridge 25" on the low e and 24.75 on the high e, from the nut. My Les Paul Smart Wood is at 24.75/24.5 and my two Ibanez ones are 25"/24.75 and the necks on all are exactley the same length. The only difference are the saddles are tweaked about the same. The tailpieces are a little different too. So, Im going to drill 1.75/1.5" back. The slant will follow the bridge.
