Truss won't tighten to fix neck relief
I picked up a beat-up '91 RG570 last week. I spent 3 days filling in all the edge chips. Started cleaning and adjusting today. The trem is way in the pocket after I got it level so I know I need to shim the neck. There was a little too much relief in the neck so I loosened the truss all the way 1st just to see how far it would move. About 1 turn and it was loose. I tightened it back up and can't even get back to where it was. I'm going to take the nut off and I think there is a washer too, and try and get some grease in there and see if I can get it loosened up. Anyone else run into this problem?
