Still wanting to further the flaps, but stalled in progress do to the miss drilled hole in the spar. I jumped on building the cradle for the flaps. I drove over to home depot and picked up some 3/4" plywood. I used the aileron rib to scribe the required angle on the wood, then I clamped two pieces together aligning the edges.

I made the first initial cuts with a circular saw, and completed the cut in the "V" with a jigsaw.

I then used a couple of 2x3's to form the structure. I decided that the "V" was a little deep so I cut the top of the holder down.

All done. I just need to install some padding on the mating surfaces.
