Finally, I finished the plan for the Neck Router Jig! A flexible tool that helps you to create/re-create your favorite necks, or to do more advanced asymmetric neck shapes that otherwise can be time-consuming.
The grip shape of the neck is important. How much wood does it take to fill up your hand? Too little equates to quicker hand fatigue. Too much is even worse. With an asymmetric neck profile (in theory) you can get a more proper playing position across all frets on the neck. To reduce strain on your wrist, fingers and forearm, the neck needs to have a supporting profile for the hand from the first and to the last fret.
