Neck Construction Part V

After routing the opening for the truss rod, I made a spline to fill the top of the opening.  This was a little tricky to cut since it was so thin.  I cut a corner off of a larger piece with two cuts on the table saw.  I wasn't sure of the exact depth for the spline so I cut it a little large.  Then I used a hand planer to thin it.  Here's how it looks in the neck before gluing in place.
