To date I've not wanted to attempt a 1 piece maple neck because of the curved truss rod design Fender uses with a single action rod. I've come across a youtube tutorial where the guy installs a double action rod (heel adjust) with a straight router channel. The slot runs right through the heel, so the skunk stripe runs from the nut to the back edge of the neck. Is this a common way of neck construction? Is there any issues with doing it this way? How deep should the rod channel be? If the neck is 1inch thick and you have a theoretical fretboard of 0.25 inches (6.3mm) I would assume the channel is 0.75 inch deep so the rod sits just under the FB. Correct? What else?
