placed on balancing madrels within a draft-free room. The mandrels are positioned under the hinge points in a way that allows the control surface to pivot freely without dragging or binding. A balance beam or jig is then installed to determine the moment arm required to balance the control surface. The beam consists a graduated measuring scale in which weight can be moved to bring the control surface to horizontally level position or other position specified by the manufacturer. Once in the proper position
