6: Neck reset confusion

That's right about where the fretboard should project onto the saddle. Very peculiar. I decided to not modify the neck joint but just shim it and glue it back together. The neck joint must not have been at fault here.

And no surprise, once it was strung up the action was the same as before.


 

7: Hacking the neck angle

After discussing with some guys online I theorized the neck joint geometry is right but the neck block is probably weak. A luthier that runs Guitars For Grunts (a charity for overseas military members) showed me how to do a neck bolt.

I used a #6-32 x 3" bolt and matching a washer and hex nut. It's not as convenient as GFG's T-nut solution (you have to hold the nut with pliers to tighten) but it works. Well, kind of. This helped my action problem by about 50%, but not enough. For the rest I took to sanding down the saddle.

The final result. The 15th fret string height is 5/64" (treble side) - 7/64" (bass side). Very playable.


 

8: Bits and pieces

Regluing the pickguard:

Somehow the trussrod cover ended up on the floor and a back over with a chair:

I used some of my two-part superglue to stick it back together.

It's not as noticeable as it looks in the picture, but it's not invisible either.

That's the new heel cap made out of 3-ply pickguard material.
