Well Bob, for better or for worse, I already extracted the graphite rod and did a spline graft, without removing the neck from the bass.
This is a cheap bass for my daughter. I spent a couple of hours on this and I think a scroll graft would take a lot longer, not including the time to remove the neck and go through all that again..
If it turns out unsatisfactory I can still do the longer and better repair.
But I think I did a good job.
