So, same story for the truss rod. First, a test run:

Then for real. This is a test fit (I know it’s upside down, but I did not create the access cavity at the nut yet, so the rod doesn’t go in all the way, and this way I can test fit the widest part of the rod):

A close up of the rod configuration at the body end:

And one at the nut (now, I flipped the truss rod over so I could see how it’ll fit when there’s room for the adjustment nut):

Now, I’ll first glue on the headstock veneers before I create the truss rod access / adjustment cavity.
