As you can see, in theory, once its all back together, the cut should be pretty much invisible. I've done a test stringing (without drilling secondary fixings for the neck or doing any sanding as yet) and the action is much more sensible, however, there does seem to be a bow of about 1.2mm (at the 7th fret- the worst spot) in the neck. The 1.2mm is with the rod slack. Cranking the truss rod does not seem to make a difference. I seem to recall bow can be corrected using clamps and a rigid thing to clamp the neck too. Any ideas on the process folks?
