Truss rod tension nut replaceable?

GeoffByrne · #1 06-29-2009, 08:21 AM

I picked up a Peavey Cirrus V BXP at a pawn shop cheapish. I suspected something wasn't too right, but on first inspection it's a pretty clean bass.

On getting it home I find the trussrod nut is totally reamed - and I mean totally.

It's playable, but not perfect, but I really like it, it's in very good condition - no wear.

Since this is a double-action trussrod, does anyone know if the nut is replacable, or will it be a new trussrod job?

I dont know about Peavey Cirrus, but I had the same problem with a tobias toby pro , i got a torx wench and eased it into the nut with a hammer and unscrewed it ,it took 1 min to do . i used a truss rod nut from a old guitar neck (Fender Rip off). you can buy nuts on ebay

If it really is a double-acting rod, you're hosed, I'm afraid. The nut is welded to the rod.

That's what I thought.

D*mn!! Ah well.

How about drilling a hole into the shaft & putting a short self-tapping screw in there? I only need to tighten the thing a bit.

Have a look here: www.mcmaster.com
Type 'screw extractors' in the Find window, then go to page 2814. Scroll down to 'Recess-Grip Socket-Screw Extractor Sets.' These are like tapered Allen keys-you drive them into the damaged head, and turn. If you can figure out which one will fit I'll bet it'll work.

Interesting site - thanks! However, if the nut is welded on, it's by the way.

Sorry - not relevant.

OK, but I'm saying you can use this tool to turn the rod. Not to remove it, just to turn it.

Ahhh!! I see!! American English

Well, that certainly might work!!!!

I must look for these in the UK, then!!

Thanks!!

OK.

Here's what I did.

As it is a double action truss rod, and the nut is welded to the rod, I've taken a 3mm metal drill bit and bored into the centre of the tensioning nut.

Then I screwed in (hard) an M5 x 12mm stainless steel self-tapping screw.

I found I could tension the neck, but couldn't turn it back (the screw came out), so I put a dab of red Loctite on the screw & put it back in - left it for a few hours & now, using a Philips screwdriver I can tension or loosen the trussrod.

Works.

I wish I'd read that a year ago, before I sold my knackered Ibanez Roadstar neck. Could have done that, would have fixed it. And that was a beautiful neck, oh well...
