Hi FW what thickness is the headstock at the neck joint. Looks like it would still be 12mm+ . If so maybe could draw file flat.
I'm not quite sure what you mean Tony? The thinnest point of the head stock is the upper corner nearest the transition, it tapers down to about 3/8".
The transition itself is pretty much a match for a factory neck, the splice/scarf joint itself is fine.
