Manual Reference: 8-6
Brief Description: Gear Tower - Assembly #13 (finished)

Lots of progress today. Mary even came out and helped me part of the time. -Radiused the edges of 8 washer for bolting the forward and aft upper cross braces (allows the washer to set flat due to the radius of the corner angles). -Riveted the Forward upper brace (F-802N-1) and Aft upper brace (F-802T-1). Had good results as I was able to squeeze these). -Put all of the AN-3 bolts in for both items above. -Riveted the throttle quadrant bracket to the left gear tower. Then added the nutplates to the bracket. -Riveted the nutplates to the mid-cabin braces (I left the ones near the attach rivets off so I could have plenty of room to buck the big AD4s that attach the braces to the tower - bad move, I had to end up bucking the nutplates due to clearances isses with the squeezers). -Bucked the mid cabin brace rivets that attach them to the their respective gear tower. Came out good. Drilled out one rivet, but not a big deal. -Put the bolts into the mid cabin brace that tie the to the WD-812 weldments. -Installed the final 4 nutplates on the mid cabin braces (had to buck them). See the other entries for additional pictures.
