That ash looks amazing, especially the back grain. Bravo! I love it.
How was making a straight headstock (with no angle?) That might be my first design for simplicity reasons.
I like straight headstocks.
they can be elagant, simple, and very rigid.
of course, some designs need an angled headstock, but I use similar straight headstocks if it is possible.
I used this even with my latest 6 string.
3+3 tuners, no string tree needed.
I use thick headstock material (~20-22mm), and make that drillings to accomodate the tuners, and for the look, too.
this way I get a very rigid HS, with good string breaking angles.
