Thanks Carl. Yes, the flap brace and bottom skins are both dimpled. My bottom skins are riveted to the wing ribs and both spars, but they aren't riveted to the Flap Brace yet.
There's a note on DWG 14B to "Dimple FL-802PP [Flap Skin] and machine countersink FL-803PP [Flap Spar]" but if there's a similar note about the Flap Brace, I missed it. The instruction to "Drill, deburr, dimple where required, and rivet the W-721 flap brace (DWG 14A) to the rear spar" were pretty clear, so I did exactly that when I got to that step.
Any idea how Van's expects builders to mount the flap when they follow the plans for this step? Your solution is a good idea that I hadn't thought of. I was considering just dimpling the hinge and riveting it together.
You're really making progress on your build! I'll have to stop in and see it next time I'm on the field.
