Hello dear friends.
I Recently started to put an effort into setting my old guitars up and fixing those that needs some fixing.
I have this not so old classic guitar. she was pretty cheap, but of an OK quality. haven't touched her in a while, but now that i have been researching and performing some set ups on other guitars, i noticed the neck in this one is quite problematic. seems to have got quite a bend just on the connection with the body. is this repairable? or even worth the hassle? if it is and anyone has had similar problem i'd love to hear how you dealt with this situation.
btw, the guitar has no truss rod.
Thanks!

Pull the frets, sand the fingerboard flat, put on strings to check for warp. If it's warping under string tension take the strings off force the neck into the same warp and sand flat again, repeat until the neck stays straight under string tension. Once it stays straight after a day or so of tension you can sand or scrape some relief into it and refret.

Looks like the dreaded neck/body joint hump. Is that what we are looking at?

Yeah looks like body joint hump. If it aint buzzing then don't worry about it. Otherwise like Shelton said.

I am starting a repair, for a friend, of a Fender dreadnought. (DG-8S) the guitar had been dropped and the neck split open a few inches from the head. The repair was done incorrectly, with the two halves not aligned when glued up. The misalignment created a back bow. Running a straight edge along the frets, the first fret has about an 3mm offset.
My plan of attack is to clamp a steel bar or "platen" across the frets and pull the neck back into alignment. Wrap the neck in a wet towel and heat the assembly to steam the neck. Perhaps I need to over-bend the neck to allow for memory.
My other thought was to detach the fret board with a fretboard removal knife far enough down and insert a wedge between the fret board and the neck. If anyone has experience with repairing neck back bow, I would love to hear from you.
