Created more control curves based on asymmetrical neck profile from first fret. Basically copied neck profile curve from fret one, added center point to mid line, relocated gumball to snap to point, resized horizontally, when close, snap to edge of fretboard. The higher up the volute harder to line up. Much smoother, not perfect, going to try to match curves better to line up zebra better. May match surface or blend surface. Almost there.
