I am working on this Tele that has serious relief in the neck, like 1/4". How long do I have to wait to get it straight? I want to start from scratch. Been laying around for quite a while. I do not want to force the rod. It's getting pretty hard to turn. Very close now, but i need more. The strings are off, BTW. Any suggestions? What happens when it does not turn any more? Is the neck NG?
