RedHeadedStranger Posted April 23 Report Share Posted April 23 Hello! I am 15, and I broke the truss rod on a Yamaha FG-75-1 Black Label parlor sized acoustic guitar. I got the fretboard off, and the truss rod out. Does anyone know the size needed, or do you know of a cheap truss rod that would work? Could I use a two way truss rod? Thanks!

Bizman62 Posted April 23 Report Share Posted April 23 Hi and welcome! What type is the original truss rod? If it's a single rod in a curved or slanted slot it's single action. If it has a flat rod welded both ends to a round one or two round rods connected at both ends it's a two way rod. You "can" replace a single action rod with a dual but that would require filling the original slot and routing a new one. After finding out which version it is, simply measure the length and search for a suitable one. The FarEast online shops may have inexpensive two-way rods, a single action rod is relatively easy to make by yourself. Quote Link to comment Share on other sites More sharing options...
RedHeadedStranger Posted April 23 Author Report Share Posted April 23 Hello, thanks for the response! It is a single action rod. It has the nut up by the tuners, and a rectangular washer down by the body. It is 371mm, and I am having trouble finding one that length.

Bizman62 Posted April 23 Report Share Posted April 23 You can take a longer one and cut the rectangular washer end to desired length. Then put the washer back in a way it can't rotate. A square nut tightened and peened works. Or you can take a length of welding rod of the right diameter and cut threads for the nut and the square anchor. Out of curiosity, in what way is the truss rod broken? Quote Link to comment Share on other sites More sharing options...
RedHeadedStranger Posted April 23 Author Report Share Posted April 23 I was adjusting it, and my muscles go carried away. And, I went way to far way to fast. It wasn't till I was researching how to replace it that I found out you're supposed to turn it a quarter rotation per day. I went like 3 rotations in an hour! I am fifteen and learn by trial and error, so now I have to learn how to fix it! Hopefully minus the error part. It is broken a tiny ways below the nut. I may have been able to remove some wood and fix it that way, but now I have it apart so I might as well replace it. Quote Link to comment Share on other sites More sharing options...
RedHeadedStranger Posted April 23 Author Report Share Posted April 23 I think I will try making one, that seems like the most cost-effective way to do it. So if the guitar is still junk once I am done, I am not out of much. 1 Quote Link to comment Share on other sites More sharing options...

I've snapped some 8 - 12 mm bolts just with an adjustable wrench. Not to mention smaller screws. Regular steel isn't that strong. Good luck with making the rod! It's not rocket science, just make sure that the rod can't rotate inside the anchor! Here's a tutorial including several anchors. Just follow the instructions for the flat bar one.: Quote Link to comment Share on other sites More sharing options...
RedHeadedStranger Posted April 23 Author Report Share Posted April 23 Thank you so much! I will let you know how it goes. It will be a good learning experience, because one day I want to build a guitar. Thanks again! Quote Link to comment Share on other sites More sharing options...
