Work continues to tune up the alignment of both the reaction and main chains of LHO Q1 (QUAD #1).  Height, Yaw, and Pitch are coupled for various adjustments, so it is an iterative process to get everything correct at the same time.  Yesterday, we discovered that during on of our "side shift" adjustments, we unseated a wire clamp on the UIM, so we had to do some minor dismantling and re-assembly to fix it.  In fact, the clamp was a bit munched on one edge, so the Class B file came in handy.
