OK. Spent considerable time tweaking the Inboard and Outboard nose ribs to straighten them so as to align to the Counterbalance Skin. Finally got what I deemed acceptable, Reamed the 3/32, 1/8 and 3/16 holes, no problem. (Page 9-2 Step 4-6) Then on to Step 7-8 for the Shear Clips. Finished the night with Page 9-3 Steps 1-3, for the Close-Out tabs. Used a part from a metal bending brake covered with blue painters tape to protect. DId NOT use rivet gun set on low, simply tapped with a piece of white oak scrap full length of tab.
