truss rod nut bottomed out?

[Milothicus]

i've got an old P copy by Profile, and the neck is a nightmare. heel adjusted truss rod and no access rout in the body...

and then it looks like the nut has bottomed out, but i need a bit more to get the neck to be reasonably straight.

anyone have any suggestions for washer-type things i can stuff in there to get some more movement? no one seems to make washers small enough.

I'd drag the neck into Home Depot or Canadian Tire & size washers that way.

I found it easier to locate brass washers in the right size for some reason. Don't forget to look in the plumbing section.

i tried that a while ago, but there's really no need anywhere for a washer that small. washers are usually added to add to the diameter of a nut or a bolt head...

i need something that's only a few mm wide...

edit: i don't think i did try the plumbing section... guess that's the next step... thanks for the tip

I found the right sized washers in a Home Hardware on Danforth in Toronto. I've found them as well lately in the hardware department at Home Depot. Bring the truss rod nut with you to check the size.

I took the neck to home depot and tried a few washers... it looks like the threaded rod inside is an M6 thread, but the largest washer that would fit inside the opening was an M4... obviously too small to fit over the rod.

i'm not sure how the outer diameter is determined.. is this a standardized thing?

You could get a needle file and file the opening of the M4 washer big enough to fit around the rod...

Also, have you tried removing the nut, cleaning it (and the threads of the rod) and lubricating it? Sometimes that is all you need to do to get the truss rod working more effectively.

For example, I recently did a setup on a Fender A/E whose truss rod wasn't taking out any neck relief. After cleaning and lubing the nut/rod, not only could it take out the relief, it could put the neck into a backbow.

You can use dry graphite, teflon lube or light machine oil to lube the nut/rod.

Good Luck!
