Attach uprights to the base and connect the track from both sides.Nut should be inserted all way down in this possition.Nut should be inserted all way down in this possition in a thumb screw (I have indpendently invented screw pulling technique before reading about it in the MK3s+ manual - Hi Joe :-)).
