What's wrong with this Fender truss rod?

[Music] I've got a 78 strat neck here it's been threaded with Jumbo's and it feels great something beautiful about this neck except they don't won't adjust the truss rods bed and the guy that sent her in and said he's afraid if he tightens it anymore he's gonna break it and he can unscrew it either so I don't know what's wrong with this but we're gonna find out okay well I'm gonna go in there with the gripper wrench it's got the tapered Allen if it is stripped it gets a good wedge effect but there's something weird whoo that rods just turning around you know what I think I think it's broken down here broken at the anchor otherwise the truss rod couldn't be turning and turning like this the truss rod is supposed to be welded at the anchor I think I'm gonna have to try and get this out I'm trying to turn it and pull it at the same time I think it's moving now I can see part of the rod it's coming oh there's the washer that's what sits at the bottom of the hole and they look knot tightens against and it's slowly coming out Wow check this out never supposed to see this end of a truss rod somehow this got unscrewed from the anchor have no idea how that would have gotten like that okay we need to get this anchor out that's the steel anchor that's ready to accept the rod that are done screwed from so to do that I'm gonna go over to the drill press I'm going on a slow-speed going into steel though the repairer magnets are real handy I've got a good thread down in there deep enough to do what I want to do I'm going to try to pull this out with the less Shatan knob and bushing polar this is a 1032 allen head machine bolt that comes with it I've got this little harness down there that comes under that and when you start tightening this that's gonna pull that up come on it's a tight fit yeah she's in there cool here's a truss rod blank 1032 thread but you have to cut it to length yourself depending on what you're building what's going through what you're fixing now I've already made this one and measured out where it goes on the fender cut it off at the hacksaw and then I threaded it with 1032 a die this anchor is gonna go into that hole and adjust it up and down to catch into that rod when I go then and when we installed the rod and shove it down that hole want to thread it into this with some JB well that's epoxy steel putty that's really strong I'm gonna go for it the worst that could happen is I'd have to pull it back out again go right down in there a little trick I use for this job is a piece of hexagonal 5/16 brass rod drilled clear through and tapped a 1032 clear through then in one end I put a 1032 bolt and screw it in towards the center and it's the jamb nut when it hits the 1032 rod coming in from the other end you've got two pieces that meet each other in the centre of the brass and they jam together when I tighten the nut I can drive the truss rod firmly into the anchor then when I want to take the brass piece off I loosen the jam nut and release the tension on it so I can unscrew it okay I'm gonna try and find that anchor with the end of the truck right and screw it in right about in that range it's touching yeah it's going right in there I'm gonna loosen the locknut that Jam not take it out gosh that's such a tight fit I'm thinking I won't even need that jb weld I'm in there clean threads into a cleaned out hole I have this new Mac bullet replacement not for a 1032 rod and the home it's one fixed truss rod i've abraded the lacquer a little bit around that hole I'll just take a little shellac and just touch it up so it's shiny and has kind of an amber color to it but man it worked [Music] you
