It was finally time to prepare for reassembling the fingerboard to the neck. With the neck sitting in the body, I taped the fingerboard to the neck in three places, and used a bar clamp in the sound hole. Then came a final check of the center line alignment and the neck scale length, comparing the measurements from the head stock end of the fretboard to the 12th fret and from the 12th fret to the bridge.
Satisfied, I removed the neck and added a piece of tape to mark the fretboard and neck alignment at the dovetail end.
Before detaching the fingerboard and applying the glue, I taped and clamped a metal ruler to the head stock to provide a mechanical stop. Then I did a dry run without glue, to figure out how I would use clamps to secure the assembly as well as to make sure that the fretboard would end up as planned while using the mechanical stop.
