So I have been building my first 2 LPs over the last year and I'm at the point where my necks are almost complete and ready to glue in. The only thing left to do there is install the frets. My concern before moving forward is if I should do something now about the truss rod rattle. I used the dual action rods from Allparts and used silicone on the ends (where the nut blocks are) when I installed them but nothing in the middle. When the rods are loose they rattle a lot and when I put tension on them in either direction they can still rattle if I knock on the fret board. Is this normal with dual action truss rods? Will this be OK when under string tension? I did a google search and searched here for a fix but most of the reply's are about the traditional single action LP rods so I'm still not sure how I should deal with this. Being that the frets are not installed yet I thought that drilling through one of the fret slots to inject something might work to quiet the rods but I'm not sure what I should use or if it will actually work. If anybody has any experience with these rods and this problem can you give me some advice on what I should do or if I'm worrying about nothing. Pulling the fret boards off (again) is not really an option I want to go through.
