Flute and straighten all of the ribs for the LE (L & R), fab a piece of J channel stiffener (had to call Van's as one of the J channels in the bundel was 'punched' with some errant holes. I can do one side while I wait for the part. Trim a couple of the ribs to fit around the spar caps, and then make cradles to hold the LE's and tanks (next section).
