I've had friend's guitars that weren't worth, maybe like a D 25 in rough shape, money for them to pay to have fixed. I've glued braces, fixed and cleated cracks, and even leveled frets unevenly from bass to treble strings to make a guitar playable. I even fixed two bad cracks that followed the fretboard clear to the soundhole. Got it to play again. Then I bought an old department store archtop to practice on. Ended up taking the back off, shaving the braces, slipping the neck block, and binding it. It had painted binding. Then I did a refret. That all was practice for building an F style mandolin. But though I could, I tend not to work on the big three. But give me a solid guitar that otherwise would never play again, and I'll have at it.
