12th fret is half the distance between the nut and the center of the bridge.
The first fret is 1/18th the full scale length from the nut. The second fret is 1/18 of the distance of the length from the first fret to the center of the bridge. The third fret is 1/18 of the distance of the second fret to the center of the bridge. The rest of them follow the same 1/18th of the distance pattern...
If you screw up the distance just a touch, it'll screw the intonation up on the rest of the fretboard.. But not all is lost.. You just raise the action way up and tell everyone you were making a blues slide guitar..

  One of these days, man, I'm gonna build a 16-fret/octave instrument (based on a 19-tone scale, minus three less useful notes).
