Post subject:  Sanded into the truss rod slot
[uncle] Well, I came back from college for Christmas which means I can work on my build! When I left the guitar last aim I was home (few weeks ago) everything was fine. I now realize that I sanded the neck down too much, because the change in temperature and humidity has made a clear outline of the truss rod slot up towards the headstock (i put a little water on the crack in the picture to help you see it better). Im using a traditional single action truss rod, not a double action truss so with a little bit of savy work, I think that this can be repaired. My idea is to get in there with a razor, and continue to break/cut the thin wood from the truss rod slot until it is a reasonable thickness, and then doing a partial skunk stripe that would only run down part of the neck. I also have two of the stewmac carbon fiber rods in the neck so strength will not be an issue at all. There is a gap between the bottom of the truss rod slot and the truss rod itself so I think Ill be able to get a good enough thickness. How does this sound to you guys, and what are your ideas to fix this? -Alex
PS: sorry for the blurry picture. If you need a clearer picture, let me know I can upload one. Image

I did that on a guitar. Fixed it the same way you describe. No issues 7 months later. Go for it!

I don't see how this will fix anything. Is your truss rod installed in a slot that is too deep?
If not, and the slot is the proper depth, and the back of the neck is already shaped, then you'll have to sand the filler strip to the same thickness, and you'll end up with the same thin strip of wood behind the rod. Unless you plan to leave the filler strip proud of the back of the neck, which I don't see as an option.

Throw it away and start a new neck....

If you ever sell this guitar to somebody (even if he is aware about the issue), chances are that for ever reason, one day, this wonderfull person will end up posting the pictures on a forum and this would instantly have people stereotype about your work and believe me, building a new neck is way more cheaper then the money you could potentially use if people know that you are selling instruments with that kind of issue...

Now if its for a personal project and that the instrument will stay in your house only for you, do whatever you want....

dude, you cant just build a guitar "just like that" in an unappropriate environnement...

-What is the % of ambient humidity in your workshop?
-How dry was the neck in %?

Its pretty hard to explain this without showing a picture, but I'll do my best. I didnt route a curved channel, it is steps routed to different depths. The channel steps down getting deeper with each step toward the center, and then steps up higher again after the center. The crack is right at the beginning of one of these "steps" so I SHOULD be able to get a good 1/8in or so of thickness if I glue the skunk stripe all the way down touching to the truss (but I cant really be sure until I pick at it with a razor). This guitar is for me, and its a neck through (replacing the neck would be a huge pain) so Im just going to try to repair it and see how it goes! Hopefully all will go well!
