There's a problem called 'cumulative error'. Hard to say what is the problem, but all those factors, bridge and fret combined will contribute something to this error. A few ideas: If you can remove the bridge and reglue it with all the strings compensated about 1.5 to 2mm, use a wider saddle, then try to adjust the intonation by moving the ridge of the saddle toward or away from the nut in each string group. Usual format - trebles forward, G string back, D in the middle basses back a bit. Or try to fit a wider saddle on the bridge a see if you can work out better intonation by moving the ridge forward of backward like above. Frets: pull the misplaced frets carefully after heating them a bit with a soldering iron. Get a set of wire snippers and grind the face flat. I can show you a pair if you don't l have them already made. Take some left scraps of your fingerboard and scrape them down really thin into veneers that fit tightly into the slots of the removed frets. and super glue them in. Then take some dust from the fingerboard and pack it in to the fret slot around the veneer if it is not completely tight. Add a bit more super glue, then scrape it flat. Re measure the fret position and clamp the ruler to the neck so it does not move when you have it indexed against the nut. Then mark the proper fret position with a knife. To recut the slot, take the first tooth of the saw or the last tooth and pull it down the knife line until it scrapes a straight groove into the fingerboard right on the line. When the groove is established you should be able to pull the whole blade through the slot and deepen it. A few more passes and you will have almost the right depth slot. Sometimes a little wax on the teeth of the saw help. ______________________ You problem sounds more like the bridge to me. But in these kinds of multi error situations you have to go back to fix everything. However one half mm is not always enough to throw intonation off significantly, it depends on the string length. Hope that information helps
