Oops my bad! I use this type of double truss rod with the nut welded on for my own “from scratch” builds. It works both ways!
Unfortnately, the call ended without them agreeing to any concrete action. Just that I could send it back again if it still has issues. They weren't even willing to say that they'd check it again just in case.
If you still have issues after you get it back,bring it to your local tech who works on guitars for a living. Get his sincere opinion and solutions.
I'm glad the OP feels that Warmoth at least 'made him whole.'
I just wanted to correct what I believe is some misinformation regarding the compound radius and the straight edge. With a compound radius on a fretboard, you either have to vary the thickness along the centerline, or vary the thickness along the fretboard edges - it's simple geometry since the fretboard width is fixed.
Another way to put it: To turn a 10" radius into a 16" radius, you have to sand down the center of the fretboard until the radius sander meets the board at the edges.
I did a mock-up of a 10" and 16" radius, keeping the thickness the same at the fret ends (by the E-e strings). The difference in thickness in the center is 0.023". So the fretboard of a compound radius will be 0.023" thinner in the center, between the D-G strings, at the pickup end.
The height of a 6105 fret above the fretboard is 0.059". The OP's straight edge shows a gap of a little more than half the height of the fret, so .023" is pretty close to that. I'm sure there is some tolerance in the sanding and possibly in the way the straight edge is being used on a curved surface.
In my own experience I've learned that the slotted straight edge is just a reference point. Ultimately we measure string to fret height for setups, and there's almost always some variation between how the frets were fit and sanded versus the plane of the fretboard.
wouldn't it be very, very, very bad if the Big W sanded down the middle of the fingerboard to get the 16" at the end? the string heights on the middle strings would be a disaster, let alone fretting something made that way. u definitely want the center of the FB to be consistent thickness, so I think they vary the edges, allowing them to "Come Up" to create that flatter surface at the higher frets. it's the only thing that makes senseI just wanted to correct what I believe is some misinformation regarding the compound radius and the straight edge.
