Hi! I have built 3 fender style guitars with dual action truss rods but with heel adjustment. My plans now to build one with headstock adjustment. The problem is that there is not enough room for the access hole if you make the headstock with the "standard" dimensions. My plan is to offset the headstock 2-3 mm more than standard. But I am concerned about the strength when doing so. I have made a drawing of my plans on a standard template of a fender style neck. What do you think? Will it work? Is there any better solution?
