Wow... what woods in the binding? I have a set of black Walnut and was thinking some AYC bindings etc for contrast would look cool. As far as the relief there are so many variables... perhaps it would be prudent to take a thin strip and do a deflection test? Knowing every piece of wood is going to be different and treat accordingly: adapt your neck profile and thickness distribution. When I’m shadowing my neck I have fret relief in mind. Once upon a time I took some basic physics for aeronautical engineering classes and we did some simple modeling fir force/load distribution, plotting a graph was a basic log curve as a function of aspect ratio, width to length, the curve started at zero at the end, think wing tip or guitar nut, and max laod at the root, say at the body/neck junction. I’ve taken to thinning my necks with accordingly getting more daring with each one. The reality is the failure mode isn’t string load but gravity induced shock ie the gravity check :/ About Ricardos comment up thread about f12 string clearance I tend to agree that 3mm is it, I hit the strings hard when I’m really going at it and anything less is a buzz fest. I find I need to bump the 4th string up a touch overall. I haven’t set a firm relief number but found I like more then less but I can get some buzz at f10-ish if there is too much, again I’m crushing the wound strings when this happens. HR
