I just started fluting the wing ribs tonight. Before starting I watched Alan Gilmore's video and read every post I could find. It all seemed relatively simple, til I started at least. I am having problems with the ribs warping side to side. I have no problem getting either the top surface, or the bottom surface flat, but not both. When I get one side done and move to the other, it messes up the side I just finished. The hardest part is around the notch machined in the upper web of the rib. The rib wants to flex at this point. The rib can be made to lie flat with minimal pressure, but I can't seem to find a way to flute the rib to keep it that way. What am I doing wrong?
