This was a quick session just to make some progress on restarting work on the right flap. These steps were the same as what I did a couple day ago for the left flap.
I started by measuring, cutting, and trimming the two pieces of trailing edge extrusion (VA-140) to match the length of the right flap skin. Next, I used the micro-stop drill cage to countersink both sides of the TE extrusions to accept a dimpled skin. Then I used my hand squeezer to dimple the trailing edge of both of the skins.
What's next? Time to rivet in the remaining skin to the right flap, and set the adhesive tape for the trailing edge.
