I remember my cousin had a Martin when I was a child. I don't know what happened to this guitar but I didn't hear him playing for too long. Maybe it was damaged like yours, he probably didn't have money for luthier service and didn't know how to fix it himself.

You did it perfectly. I can't believe this is the first time that you tried to repair a guitar. Did you search for any tips or you simply just used common sense and did what you thought was correct?

I can imagine people coming to you with their broken guitars now :)
