I calculated the tool-paths using Vectric Cut3D. The machine is controlled using EMC2. The roughing toolpath used an 8mm diameter endmill and the finishing toolpath used a 12mm diameter carving core box bit with an extra long shaft from Wealden tools.

I also used a cut-out tool path which cut out the machine head holes and trimmed around the edge of the neck.

You would also need to add a pocket for the truss rod and maybe drill some small holes to secure the machine heads as well. I didn't have any neck hardware to hand so I left these steps out for this prototype

You can see the indexing dowels in the second and third photographs below.
