Neck bow repair

    I picked up a 70's P bass as a project to fiddle with.

    It has a bow in the neck I cannot seem to get flattened out. I have removed the neck and loosened the truss rod screw. I then clamped it up straight for a week. No luck. The truss rod will not tighten by the way.

    Any thoughts would be appreciated.

    Can you get the truss rod to tighten? I have read in Dan Erlewine's book you can loosen the truss rod, clamp the neck with a reverse bow !!using padded cauls!! then tighten the truss rod down with the reverse bow. Also you might need to make a spacer washer to put on before you put the truss rod nut back on because the wood might be too compressed that the nut seat against.

    You might notice by doing this that when you string it back up you have a back bowed neck, but you can slowly loosen the truss rod until it suits the amount of releif you need.
