Help. Truss rod Problem

Hello.

I need really really help.

I have Ibanez guitar. J-custom.

Today, I need adjust neck because I have buzzing from changing condition.

It looks upbow and I adjusted Truss rod counter-clockwise. and the problem occurred when I turn it.

Only Trussrod 'Nut' is just loose. Just only nut. I can't explain exactly in english.

Truss rod nut(in headstock) loose off from truss rod. so It still work clockwise(because it is fasten direction)
but CCW isn't work. just loose(unfasten) only nut without adjust trussrod.

How can I fix it? Super Glue?? ugh...

DO you still have strings on the guitar and up to tension? If yes, good! Give the neck a few days with the truss rod nut loose. the neck should straighten up a bit.

Thanks.
Is it work? Neck condition isn't problem. The Problem is truss rod 'nut'.
It just unfasten only nut not with truss rod.
So I need 'How re-fasten again truss rod nut with truss rod'.
How I make torque enough again for CCW adjust.

Re: Help. Truss rod Problem

Do you mean you have removed the nut from your truss rod and cannot screw it back?
Just show some pics.

Yes.
This Nut Unfasten along.
Truss rod nut and Truss rod will be locked tight each other, because it will be not loose each other when it turn to CCW direction.
but my guitar's truss rod nut isn't lock tight enough maybe.
When I turned to CCW direction for fix upbow, it loose along from truss rod.
I was tight back turning Truss rod Clockwise little bit(about 45 degrees) again for making torque, but it can't make enough torque. so It loose along easily again when I turned counter clockwise.

Re: Help. Truss rod Problem

Let's familiarize ourselves first. This is what your truss rod looks like out of the neck. Are all the parts I have labeled in good working condition on your truss rod? Is any of it broken?

Re: Help. Truss rod Problem

There are those types of truss rods :



Wonny will not be able to fully remove his truss rod, unless this is of type 1 or 3.
Are Ibanez truss rods removable ? The one Ryc showed seems like type 3. If so, wonny might remove the truss rod and examine thoroughly as pointed by Ryc.
In types 1 and 3, the nut is not supposed to be removed from the main body of the twin rods.

Wonny is working with a J-Custom which has the same rod as the one I pictured. All MIJ necks have these rods. It's not removable unless you take the fretboard off, as I did. Mine is from a 2001 Super Wizard neck. The nut and washer should be easily removable.

Re: Help. Truss rod Problem

You loosened the nut to get rid of backbow and it's loose, but you still have some backbow?

If that's the case the neck needs to be trained into relief by clamping in a jig and heated/cooled several times to get the fretboard glue to slide.

Does it have some kind of anchor to the other end (neck heel end)? Or just there is not enough room to get it out, which type is it? :

a) vintage type with anchor on the other end (gibson, fender style)
b) twin rod double action
c) twin rod single action?

From your pic it seems like c), can you show it as a whole in some pic?

This is what I was trying to figure out too. The language barrier is a little tough. I can't tell if the nut broke off with threads attached, the threads are stripped, or if all the parts are OK and the neck is stuck in back bow.

It's a twin rod double action of Ibanez' own design. Here's pics of the whole thing.

Aha, I see, thanx Ryc. I had the impression that in twin rods double action designs, the nut (if present) is never meant to be screwed out. How does this design make sure that the grip on the nut/rod will be greater than the rod/threads on the bushing?

I think wonny said/implied that the clockwise function works OK.

not totally sure of what your asking but this is how the Ibanez rod works: I think it's the same as all dual action rods.

In the pic you can see the sleeve. It is not attached to the main rod, only the "action" rod. As you tighten the nut, it pushes the sleeve forward (toward the heel end) on the main rod. Both rods are welded together at the heel end. This tightening, in effect, shortens the main rod. Because the ends of both rods want to be flush with each other, the torsion forces both rods to bend- other wise known as backbow.

Sorry- forgot the pic.....
