Ran into an issue while trying to finish up the horizontal stabilizer. Everything thus far has fit like a glove, until now. Page 08-12, step 3 has you to insert the rear spar into the stabilizer, cleco it to the backs of the inspar ribs, and then rivet it to the ribs. Step 4 then has you to rivet the skin to the rear spar flanges.
Most of the holes line up fine and can accept the -3 flush rivets with no problem. However, for some reason, on both top and bottom, and at opposite ends, the holes get off alignment somewhat for a series of about 20 or so holes in a row. It wont help to take out the clecos and slide the spar down a bit, since the misaligned holes at one end are in the opposite direction as the other end. In other words, correcting the alignment at one end will only make the other end worse. The plans never had you final drill these holes at any point. Pictured is my worst case misaligned hole.
I may be able to force the rivets in, but worry they will be angled excessively to one side.
Of course my other option is to final drill the holes with an #40 reamer which I do have. Bad part about that is the holes in the spar would no longer be perfectly round.
Has anybody else run into this? Am I splitting hairs here?
Any suggestions are very much appreciated
