Well my wing is starting to take shape which is really neat. I have attached the main ribs and rear spar and now I am starting to put on the nose ribs. Having heard about some troubles with the wing doubler, I tried a dry fit before I riveted the nose ribs. So I clecoed the inboard nose ribs and forward stub spar and to my surprise the aft row of holes on the wing doubler does not line up with the row of holes on the spar! All of the other holes do line up on the ribs. I just don't see how this is going to line up without some major pressure. Also the third inner nose rib seems compressed. Has anyone else had issues with this?
OK. I did a bit of experimenting and here is what I found. I must be making some mistake because if I clecoe the inboard nose ribs to the factory attach angles, the flanges facing the spar on the second and third nose ribs under the wing doubler are NOT flush with the spar. If I clecoe the second and third nose ribs to the spar the holes now DO line up with the wing doubler, but the holes in the nose ribs do NOT line up with the factory attach angle! The fourth nose rib is fine. The first nose rib is a lost cause. So what I see as the common denominator is an extra layer of spar doubler for the first three inboard nose ribs. It is almost as if the first three nose ribs need to be made .046 inches shorter to accommodate the extra spar doubler. Am I making any sense?
Now I am starting to see a problem. Looking at the nose rib attach angles, the distance from the holes in the attach angle to the bend in the attach angle decreases going outboard to inboard to accomodate the additional layer of spar doubler. There is no change in the distance for the inboard most three attach angles appropriate for the final spar doubler. So now I wonder if I have a bad spar.
