The aileron trailing edge ribs and the flap trailing edge ribs are almost identical except in length. In hindsight it would have been faster if I had only made one set of form blocks for both ribs.
Here is a view of the form blocks used for both the aileron and flap ribs. The first set was made of MDF board but I found that MDF did not hold up very well when making these ribs, particularly at the very aft tip of the rib. I finally made the form blocks from oak which worked much better.
Here are the first two aileron TE ribs. Although the picture does not reveal it, I did not need to apply too many flutes to achieve the necessary contour.
All of the ribs have been formed and the lightening holes have been flanged.
I used the "modified Bob-stick" with a taper on the nose. This worked much better in these smaller diameter lightening holes.
