Joshua,
I wish you the best of luck with your build(s).
I don't want to seem negative, but I think that most of the people here are telling you correctly.
There is a huge difference between using a CNC for a body blank and using it to carve around an existing and expensive neck.
I you are hell bent on using a CNC then CNC the whole thing, not just the wings around the neck.
Also keep in mind that this form is MOSTLY comprised of people who are hobbyist builders who build guitars for the sake of building.
For many of us myself included it's not the goal we love, but the process. So you will encounter a bit of hesitation from a lot of us when a first time builder wants to take a lot of shortcuts into building. (Not that CNC is a shortcut, it is an art form all to itself, but you don't have any experience with that either)
If you just want a custom guitar built without having to do any work, call a luither.
If you want to build a guitar because you would enjoy the process of taking a bunch of un-cut wood and turning it into a work of art, then slow down.
Read some books on building. Try to understand why we do the things we do. Learn the balance between what is nice to look at and what is functional.
And finally, a honest word of advice.
Your first 4-5 guitars will be ugly and have many mistakes (CNC or not).
This is a hobby that takes time, money, blood, loss of relationships and patience.
If you really want to learn to build guitars, try this:
Return the neck and other parts you have ordered.
Buy a Saga kit and fully assemble it.
This will teach you the fundamentals of assembly
Next
Buy a body blank and neck blank from Stewart McDonald.
Build your own guitar BY HAND from blocks of wood. This will give you a better understanding about:
Shape, Weight distribution, ergonomics, PLANNING, Electronics design, the world of fretting and intonation, finishing and the sense of a job well done.
Then
Build another from scratch.
Then another
Now, if you still like the idea of building a guitar, go talk to your CNC operator buddy and work on it together.
I hope this does not discourage you from building, but this stuff take lots of practice and time to get right.
You will find that this can be a great community for serious builders.
