I got the root rib aligned and drilled today. I also placed #3 and #4 rib but had to drill out a few of the 46's since they were breaking off oddly. I remedied the problem (it was my technique) and seated those ribs down nicely. According to plans there are some rivets that should go in the opposite way and I did not remember to do that so I will contact Kerry and see if I should drill them out. I also have a question on root rib rivets. Plans seem to indicate the head should be on the attach angle side but riveting would be virtually inpossible. Other build logs I notice people putting them in from the outboard side and that would be far easier. Had to break for Mexican food.
