That is what I did to one hole that just never seemed to line up right after I finished building the wings on N357CJ. I ordered the next size bolt which is I think a metric 10 mm and matched drilled the very small amount of miss match of the one hole. So the big question is just how much miss-match is there from hole to hole???? Joe Horton Coopersburg, PA

Now that I think about it, that's exactly what I'd do if it were mine. Mark Langford ML at N56ML.com http://www.n56ml.com _______________________________________________
