				Not a dumb question Andrew,
 and you don't have to be embarrassed as we've all made minor mistakes.  
 The hazard is not correcting them when we see them.
 I'd recommend you make adjustments that allow you to lay a yardstick or 
 such across the ribs to get them aligned.  It may only take
 drilling out the rivets, or clamping and drilling for the next size 
 rivet, or making the rib over.  This would be a good time to learn the 
 art of
 replacing a bad part with one built from scratch.  It'll save you a lot 
 of money.  The misalignment would probably be easily seen, so
 I'd go for the fix and hold onto your sense of what's right.  Go for it.

  Hey everyone,  I am looking for a bit of advice on my rib alignment for my rudder.  I am getting ready to rivet my rudder "skeleton" together this weekend and noticed that my 3rd rib is approximately 1-2 mm off center.  The lip of the rib actually is recessed a tad on one side and protrudes a tad from the spar on the other.  This my be knit picky or it may not be but I am new at this and would like to know if this is within the tolerances of the design.  I am learning a great deal about what methods get me the best results right now so I apologize if this is a dumb question.  Thanks in advance,

				That much mis-alignment will probably be noticeable in the finished 
 rudder. Re-clamping and carefully drilling out the holes for A5 rivets 
 will probably fix the problem. If not, making a new rudder rib isn't 
 very difficult, its just a two straight bends.
