Interesting Trussrod design

#4
I got a few similar to those from a guy who used to work at Ovation when they imported Warwick. I don't know if that's what Warwick used or not - it might have been from something Ovation made.

They seem okay. I've only used one. I don't know if they can produce the same kind of force that an all-steel rod can.

what steel threads potentially stripping are you referring to there, Hammy? this auction item is listed as aluminum :eek:

I sense a stripped truss rod just waiting to happen. there's a reason that this is a left over from an old guitar shop

All the best,

I second that! Al is not good for threads on that higher stress area!

It's bad enough I have to assemble an engine with head bolts into aluminum!

I don't think Warwick used them. Since 1998, all basses have fixed steel truss rods and steel reinforcement in the neck, according to my repair manual. Might be from Framus Guitars, though, as they are closely affiliated with Warwick.

It's a neat idea, and simple enough for the average garage machinist (though cutting the threads in square stock would be tricky for some). I actually have bezdez in my favourite sellers list just because he/she/it's always selling this kind of stuff.

A bit of figuring and you could probably make it into a serviceable two way rod, too.

But what would the advantages of this design be? Would the flat bottoms interfere with one another, thus preventing the rods from actually doing what they are supposed to? And if not, how can one thread metal that isn't round?

Potentially cheap, easy to fabricate, or light in weight. Plus requiring a shallow rout.

Possible, but not likely.

You put pairs of flats together to make squares, then turn down the ends. For the smooth bars you turn down to the minor thread diameter, minus some clearance; for the threaded bars you turn down to the recommended stock size for the threading die, which you then run down the two of them together. Now you've just made the bars for two truss rods.

I am interested, though, in JP's negative experiences with these.

If I'm reading him right, he was referring to the aluminum Warwick version. I've heard horror stories about Warwick aluminum trussrods but I didn't ever know their design. I would easily concur that an aluminum version of this wouldn't be good at all.

I'm interested in this since I make my own trussrods. This one in the Walnut Fairlane is like the Warmoth version - rod and bar - but I think I overspec'd it's stiffness and it's only a single action. I've figured out how to easily make it a double action but the design takes a little more work to get it installed correctly. I would rather just rout a very simple channel for installation and this design would only require a flat bottomed channel - the simplest to cut.

I can't get access to e-bay any more (or to photobucket and similar...yuck!)
Can somebody mercyfully copy a pic or two into this thread? I'm nearly fainting from curiosity:help:

Do you think there would be a significant chance of buzz when you didn't have much tension on the rod? I would probably want to come up with some type of thin insulating material between the rods just to be safe. As others have said, I like the simplicity of this design, looks like something I could have the guys at the machine shop throw together pretty quickly in custom lengths. How 'bout the nuts though, is that style nut readily available?
