A few more quality hours spent with ribs today, but I'm finally done with deburring, bending flanges, and fluting. The fluting turned out to be a non-event, as the vast majority of the ribs were very close to okay as-is. In most cases I actually had to unflute (deflute...antiflute...?) with the hand seamers because the parts were already a little overly corrected by the flutes that Van's puts in. The first few parts had me scratching my head trying to figure out the best mode of attack, but after a few ribs it became pretty easy to tell where to flute or flatten a rib to make it warp in the desired direction. The twist of ribs throws a little wrinkle into it all, since a rib can be perfectly flat in terms of the warp but still have a twist to it. The twist is apparently just fine for construction as long as the rib is otherwise flat though.
