Replacing a broken truss rod

This Gibson EBO bass had a broken truss rod, and the neck had too much bow in it. Because we could hear it rattling in the neck near the neck pickup we had a pretty good idea it was broken at the anchor. The first step was to pull the rod out. Ron tapped against the nut until he could get ahold of it with a Robogrip and PULLED!

Once it was out he could use it and magnets to locate the anchor. Next step was to remove the last 2 frets and drill down into the fingerboard to hopefully expose the anchor with the broken end of the rod still in it. It worked! He cleaned out the hole and removed the anchor. Since the rod was long enough he threaded the broken end and extended the threads on the other end where the nut goes. Next he cut a new anchor from a piece of bar stock, drilled and tapped it.

The repaired rod was then waxed, threads and all, and pushed back into the neck. The wax is a lubricant to help it slide in and also helps lubricate the nut. Then the new anchor was ground to fit perfectly in the neck and a mahogany block glued in place to keep the rod from moving. Next step was to make the repair disappear. Ron cut the hole in the fingerboard to a rectangular shape so the ends of the plug would be hidden under the frets. He found piece of Brazilian rosewood with similar color and grain pattern, fit and glued it in place, cleaned it up and oiled it, put the frets back in exactly as they were, and……what repair? Works just like new! Read For More Information - https://stpaulguitarrepair.com/2018/05/22/replacing-a-broken-truss-rod/comment-page-1/#comment-744

How To Clean And Maintain Your Electric Guitar Fretboard

Finished and Unfinished Fretboards The guitar community is torn in a debate about whether the material of a fretboard makes any difference. Some believe that a rosewood fretboard is markedly different from ebony, while others say there’s hardly any difference. But when it comes to cleaning, you will need to be cautious. Primarily, the focus is on fretboard cleaning, but other guitar parts are involved, like the neck and tuning pegs. And if your electric guitar has a fretboard that uses unfinished wood, things are tricky, demanding extreme caution. So, it’s recommended to oil unfinished fretboards for obvious reasons. When you leave wood for a long time, it turns hard, thereby making it difficult for the truss rod-neck adjustment. Unoiled fretboards can also crack in places that look bad and hamper your guitar play. How To Start Cleaning Your FretBoard For maple fretboards, you don’t have to spend time oiling. Typically, they are pre-hydrat...

How to Repair Binding around the Body of an Acoustic Guitar

What is Acoustic Guitar Body Binding? Almost all acoustic guitars have some type of binding around the edges where the top and back meet the sides. Many acoustic guitars also have binding around the fretboard and peghead. Acoustic guitar binding can be made out of many different kinds of material including: various woods, plastic, or celluloid. A “true” binding around the body of the guitar is inlayed or glued in a channel cut from the body. A router is used to cut a small channel or shelf on the edges of the guitar for the binding to sit on. The binding is then bent and shaped to fit the body and glued in place. Most of the time decretory purfling strips are usually inlayed next to the binding. Purfling strips are thin laminate pieces of wood dyed different colors. You might ask, what is the purpose of binding on an acoustic guitar and why don’t all guitars have binding.
