Help with Peavey Foundation truss adjustment

Hi all,

I am trying to set up an early 90s Peavey Foundation that has too much back bow. I've tightened the truss by about a full turn and a half which hasn't had much effect.. at least not as much as I expected. It's a hex nut and I've noticed that the pin inside the nut rotates with the nut when I turn it. Should it?

Should I keep on turning the nut or is there something else going on? I usually leaves any truss work to my tech so I'm pretty clueless about this kind of thing.

Item #6106 is recommended as a tool. Is this the tool that you're using for adjustment?

Food for thought:
How hard to turn truss rod?

Too much back bow? Then you need to LOOSEN it!

Take this to a pro. If the trussrod itself is spinning you have a big issue

Sorry, it's actually up-bow and I have been using a proper sized socket.

So the nut should turn around the center pin (like a nut and bolt) and isn't pressed together? I'm pretty sure the truss isnt broken.

Appears to be so. Stop, and take it to someone who knows what he/she is doing.

From your photo, it looks as though the trussrod nut may be rounded over enough to be nonfunctional.
