One more idea. Move the nut one foot to the left so that it rides on the unworn part of the screw. Then use a one-foot-long spacer to connect the nut to the machine. You do lose one foot of travel.
About Andy's idea of not using a spring between the two nuts: That works if the screw is really well made. My experience is with cheap screws and you need the spring to accommodate the variable screw pitch.
