Banged the tailpiece ferrules in with their ground wire, then shoved the neck in the pocket and attached one string to check the alignment and fit again. Still not totally sold on the neck pocket, its just a wee bit too tight in one corner and cant be pressed in all the way for a solid base measurement, but I can fix that in due time if needed. On this test fit I could fret all but the bottom three notes cleanly, so that tells me Im not too far off the mark.
