Made quite a bit more progress on covering both flaps. We glued on all chord-wise tapes, and also installed doilies around the fabric backing plates. Also fixed a small fabric tear in one location with a patch. We decided to place the drain holes in the aluminum trailing edge, which means we could use the trailing edge tape to protect those holes without adding additional doilies. We drilled 1/4 inch drain holes in each bay of the flap (in the aluminum piece). Would have been much easier to do this if we hadn't already covered the flap in fabric, as deburring the metal was a bit of a pain...so this is a lesson learned and we will do this in the right order when we cover the ailerons.
We glued on all the chord-wise tapes, and then attached the 3" trailing edge tape, using irons to smooth it all out as necessary. Finally, we used an old soldering iron to burn through the fabric at the location of each drain hole. Hours: 6.5
