How would you shape these headstocks if you had 3+ to do? That's how I plan to do these, in small groups, shaped from Allparts or USACG necks. I'd like to achieve as little variation as possible; you can see my first two guitar headstocks are slightly different. A pin router, standing drill press or CNC are not options, space is limited to smaller power tools (router, scroll saw, etc.). In my mind the areas of concern for tearout are the end of the headstock and the "mouth" of the cutout which has a 1/4" inside diameter. How would you do it?
