Hand finishing



The neck still needs some hand finishing before it is ready. First you have to cut through the tabs to free the neck from the blank. Then you have to sand away the machining marks.

The final photo shows the four previous attempts - which were less than perfect. The final attempt turned out left handed - I must have flipped the model in Cut3D!

Roughing and finishing the neck



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.

Drill indexing holes in the neck blank



I used pine to make the neck. This is not the normal wood for guitar necks, but it is cheap and you make need to have a few gos before you get it right. The piece was around 28mm thick, 106 mm wide and 738 mm long. The two sides you will be machining should be as parallel as possible.

Fix the neck blank to the spoil board - with clamps or double-sided tape whatever works for you - make sure the toolpath doesn't collide with your clamps. The blank should be aligned centrally with the spoil-board.
