Nut is compressing wood at bottom of truss hole on heel of my maple Mayer signature Strat neck. As wood compresses over a couple weeks, guitar relief gets higher resulting in buzzing at upper frets. Cranking the nut down straightens neck only to compress more wood with the pressure and couple weeks later, back where I started. Was using washers but that is not solving the issue. Considered a couple options: 1) Supergluing a 2.5 mm sleeve down in the hole so the truss nut has something more secure to press against.? 2) Modifying something like a EZ-Lock threaded wood insert to remove ID threads (so it doesn't affect the truss rod). This screwed in insert bites into the wood on the outside of the hole as you screw it down to the bottom - would be approximately 2.5mm high - trust nut would press against the threaded insert and provide a more stable base to press against when adjusting the neck relief. 3) On the flat part of the neck heel (on side that screws against the body) to cut a thin slot of sorts down toward the truss rod (and on either side of truss rod, then inserting a metal U-shaped flat piece of metal that would essentially appear at the bottom of the truss hole thereby providing a metal platform (supported by ints placement through the wood) for the truss nut to press against without affecting the truss operation. This option would leave a small slot on neck heel screw side which could easily be masked with filler (mine has a fender barcode manufacturing sticker there I could hide it under). This last method would require the most precision in measuring and installation I feel. Any other idea -or- can you see any of these working.
