Asherman Posted March 2, 2009 Report Share Posted March 2, 2009 The routed area for a truss rod... is it the same depth the whole lengh? or does it need to curve down? (does anyone have a sort of cross section picture of a guitar neck... real pic or diagram) cheers. Quote Link to comment Share on other sites More sharing options...
KeithHowell Posted March 2, 2009 Report Share Posted March 2, 2009 It depends on the design of the rod. The Fender/Gibson design requires a curved channel, the lowest part of the curve (ie furthest from the fretboard) being about 6mm (1/4 inch) more than the ends. The rod is then covered by a curved fillet which pushes it into the shape of the curve. The stew-mac hotrod and similar designs as well as the double rod designs ( the rod is bent in half and the adjstment nut acts against the rod not the wood of the neck) require a flat channel. I have seen a design, by Yamaha I think, where the rod (Fender/Gibson style) is put into a straight channel, however the nut end is shallower than the body end. Ie the rod is the hypotenuse of a triangle with respect to the strings and gives a counterforce on the neck when tightened. Hope that helps.
