Day 8: Drawing out the head and making an accurate mould in plywood.
Day 9 and 10: Copy the headstock onto the wood using the template, cut it out and finish the sides. Mill out the profile for the construction of the tuning keys + finish the transition. Draw the profile of the joint on the neck.
Day 11: Finish the neck profile joint + glue the heads on.
Day 12: Remove upper part of transition from neck to headstock + measure length of neck and saw joint roughly. Drawing the profile back of the neck and rough shaping it with cuts. First cut.

Here is the mould for the head and a first specimen sawn out and roughly finished.

Follows the finished back of the head and the profile for gluing to the neck. At the top, a glued set.

Here are the three copies with the first cut already removed to obtain the profile of the back of the neck. The profiles for fitting the tuning keys on the headstock are clearly visible.
