Clecoed the vertical stabilizer frame to the jigging angles (KPVS0081 and KPVS0082) as described in step #23 and figure 02-23.
Used a laser level and the adjustable feet on the work table to verify that my worksurface was level and perfectly flat.
Used a straightedge to verify that the vertical stabilizer ribs are flat so that they would lay flat against the skins. NOTE: I used the carpenter's level (see pictures) as a straightedge, not as a level. No adjustments to the ribs were necessary.
