Got back yesterday after being gone for 2 weeks. Resumed work on the aircraft today. Fabricated the last two A-1206 Pivot Brackets. This time I used a hack saw with a metal blade. It seemed easier to use except for the manual part. Unfortunately, I can't find one of the brackets I made before. I may have to buy another AEX Tie Down to make another bracket. Match-drilled 2 holes in the A-1201C-L Outbd NoseSkin and A-909 Aileron Counterbalance. It was slow drilling through the Aileron Counterbalance. Deburred the holes and edges of the counterbalance and the A-1203 Spar. Riveted te W-1216B-R Hinge Ribs and the W-1216 Hinge Rib Assemblies. Also deburred the W-1201B-R Inbd Upper Wing Skin.
