1 hr. mostly frustrated...  Rib 9's flange which connects to the main spar doesn't seem like it was fabricated properly.

Holding Rib 9 against the stiffener on the main spar you can see that the flange holes don't line up with the main spar holes.  Seems to me the flange was bent too far down resulting in it being wider than it should have been.

So, I tried banging it as you can see here to get the holes to line up (though this doesn't seem to me to be dimensionally the same as if it were bent correctly at the factory).

After lots of banging.... Still well off...

Inside view where you can see the part is getting pretty scuffed up in the process (and it still doesn't fit).
