Re- slotting the bridge for new saddle

Dear All,

this is my biggest challenge so far ( since I start repairing guitars),

here is the situation:

the slot of the bridge where the saddle bone set in, is oversized, I dont remeber how it happens long time ago , maybe by using wrong type of file,

the slot was too wide and the bottom of it is not flat, so I glued a piece of wood and wood filler to block it and slot it again,

the problem now is I am not sure how to locate to slot center line - where it should be on the bridge - I don’t want to have intonation problem,

I don’t remember the exact scale of the guitar I think it was less than 650,

so , how I can locate the exact place of the saddle slot to slot it again?!

Measure from nut end of the fingerboard to center of 12th fret. Add a 1-2mm to that measurement and that would be the approximate distance from the 12th fret to the leading edge of the saddle. It varies according to the accuracy of the fret location and string height. Caution, this will not work if the fingerboard has been compensated.

If the guitar was playing in tune before you filled the slot the simplest method would be to make your new slot line up with the leading edge of the old slot location.
