Sounds like they may have kept this in a damp area. I know people who have their quilting machines in their garage. I don't know how it would be fixable if the rails are warped. I have the 120 grace frame. And my rails are not warped. I keep it in the sewing room in the house. And the machine just glides. I would be worried about warped ones.
