Floyd rose nut question

[tpruitt]

So the last few weeks I’ve been dealing with my nuts moving. There swinging from..kidding.
Seriously though there moving. Both guitars use top mounted nut screws. 1 is a Ltd KH and the nuts moved so much the screws no longer would get snug so I tried toothpicks and wood glue but it’s still not tight enough to hold the tuning . 2 is a prs that’s flexing back and forth and not returning to tune either but not as bad.

How do you guys keep those tiny azz screws to hold the nut in place and not move under all that pressure?
And how do you permanently fill those holes to make them stable again ?

Here’s how I check.try this out if you get a second. Tune guitar. Dive bomb once all the way down like your Evh. Now check your tuning….with a tuner!

You could redrill a slighty larger hole in the nut but you would have to mill new countersinks in the nut if the head of the new larger screw doesn't fit flush in the original countersink.

You might be able to fill the original holes with an epoxy like JB Weld and then redrill for the exact same screw size. I assume the KH is a Maple neck and the PRD is mahognay???

I am not a luthier so these are not tried and true fixes I'm just throwing out ideas. Maybe consult a luthier and see what he suggests.

How are you sure it's moving? Can you see it move?

Yes. I can hold it up behind a light and dive bomb and I can see it move away from the fretboard.
Now my guitars with screws in the back like charvels and Evh guitars are rock sold and hold there tune. That’s why I said those top mounted screws can’t hold the pressure very well.

On the Ltd I was actually thinking about filling the holes with a maple dowel and redrilling. But the best solution I think is drill it for rear mounted screws.
Just a couple ideas.

You may not be able to drill rear mount holes due to truss rod placement so be careful with that.

You can try a Graph-Tech Un-Lock.

If you know a good luthier he would be able to tell you the best route to the best repair. I imagine a luthier would drill an oversized hole in the old top mount screws, plug them with hard maple then drill new holes for the old screws. The luthier could also tell you if installing a rear mounted Floyd locknut would be possible.

All my floyd locknuts are rear mounted.
