Matchdrilling the right wing tank - Again - 4 hours

Assembling the wing tanks was much easier this go around than compared with the last time. I cleco'd the couple leading edge holes first and then worked each side from front to back.

I was very pleased with the alignment. I used a #19 reamer to match drill the holes (again) and i was careful that the holes in the ribs and baffle are not oblong due to the second go. I then set the countersink cage and countersunk the skins exactly how I did it before. Aiming for a 0.162" diameter countersink.




All done with the right tank, so I began to cleco the left tank. All I need to do is match drill the tank and match drill all the stiffeners. I'm just about back to where I was.
