Members guitargod0dmw Posted November 25, 2007 Members Share Posted November 25, 2007 Ok...so I just picked up a Warwick Thumb 5 Bo for dirt cheap because it has a broken truss rod. I've told told that it's not worth the trouble to fix, but I just went through all the trouble to remove the fretboard from the neck to get at the rod...so the hard part is over! Here is the problem... The rod adjusts from the top...by the peg head. It was just free spinning. The little block at the other end wasn't attached. So my question is, how is this piece attached? Is it free floating, or does it actually crimp on to the rod? Here are some reference pics... Rod & said piece... Rod as it should be...but the piece is just sitting there. It can fall right off. I assume that I should just get a new rod, but if it doesn't need to be "attached" then I would assume I can just use this one. I've never seen a truss rod to know how it should be. I can thread both pieces if necessary. BTW: I removed the fretboard with an iron set of steam and a putty knife. It was a pain, but it came off pretty easy. Here are some more pics...

Members Richy Posted November 25, 2007 Members Share Posted November 25, 2007 The fact that the truss rod is no longer inside the bass is very bad. I hope you got a discount for this. Link to comment Share on other sites More sharing options...

I got a huge discount. But...I took the truss rod out of the bass. It was all in one piece 2 hours ago. Then I took it apart... Link to comment Share on other sites More sharing options...
Members Deacon_blue Posted November 25, 2007 Members Share Posted November 25, 2007 I would either silver solder the original part back on or - thread the end of the rod (10-32)and get a new end from StewMac. After you thread the new piece on you peen it over.Being European I would guess the diameter is .196", close enough to 3/16". Link to comment Share on other sites More sharing options...
Members willsellout Posted November 25, 2007 Members Share Posted November 25, 2007 I hope this works out for you man..I have no advice other than to say, why not put a new one in there? Call Dana B. Goods and ask for a replacement and advice. They should hook you up. Dan Link to comment Share on other sites More sharing options...

Solder won't be strong enough to hold, you need a weld to hold up to that kind of stress. I agree, a replacement rod is the best way to go, preferably one that's double-action.

Moderators Kindness Posted November 25, 2007 Moderators Share Posted November 25, 2007 I'm impressed you are trying this. A new rod is the best bet at this point. Link to comment Share on other sites More sharing options...

Moderators Kindness Posted November 25, 2007 Moderators Share Posted November 25, 2007 the metal end-block is not supposed to be attached. Roger, it is my experience that functioning compression rods have their end blocks welded or rivited to the rod to prevent any movement between the two piece. If the rod were able to spin freely within the end block, there would be no counteracting force to create the compression needed. Am I misunderstanding something?

If the rod were able to spin freely within the end block, there would be no counteracting force to create the compression needed. Am I misunderstanding something? I've seen it both ways. This rod looks to me like the end block just acts as a "camming" mechanism. In this manner, the rod could travel no further because of the block. Now, when the threaded end is tightened and trys to travel, it would cam against the end block. I certainly could be wrong. I was going to suggest that since he has it apart anyway, for him to adjust the rod to see what kind of tension, if any, can be applied.....or, if it just spins like you mention.

Members Jazz Ad Posted November 25, 2007 Members Share Posted November 25, 2007 Ask Warwick (in USA, Dana B. Good) to send you a new one. They may do it for free, it happened in the past.It's a bit late to tell you that but on most warwick basses, the truss rod can easily be replaced without removing the fretboard.

Ahhh...down here we call that "Brazing", not soldering. Different strokes, I guess. Link to comment Share on other sites More sharing options...
Members mrcrow Posted November 25, 2007 Members Share Posted November 25, 2007 you can buy truss rod bits i think on stewmacbasically any rod will do which will take the tension and can be adjustedthe threads on that one look stripped..and for the life of me i cant figure out why the block just slips over the end..you can get the block drilled out and get an thread insert put in if you want to use it again..it fits the routand the rod can be easily swapped for another of the same length and thread to suit the insertthe head of the rod will have to fit the headstock recess and be able to be turned easily with a tool..grease the threads before reassembling http://www.alliedlutherie.com/truss_rods.htm Link to comment Share on other sites More sharing options...
Members guitargod0dmw Posted November 25, 2007 Author Members Share Posted November 25, 2007 the threads on that one look stripped..and for the life of me i cant figure out why the block just slips over the end.. There are no threads on that end...and the other end is in great shape. I can't figure out why it would just slip over it either, so that's why I ask if it's supposed to be attached. I'll ask Dana about it... Link to comment Share on other sites More sharing options...
