Actually did this one without referring to the construction notes. That was big for me. Just added some construction pictures showing something different from the right flap. Now that it is completed, I will dremel off hinge eyes in the middle of both flaps, cut the hinge pin to proper size, bend them, make an attach point and secure the attach point to the flap spar.
Here is a youtube video of riveting the top skin to the spar.
Ribs riveted to top and bottom skin
Flap attach bracket partially riveted. The side pieces go on after riveting on the end rib.
