I match-drilled the final two places on each of the nose ribs of the right flap. Then I installed a bolt and some washers in the two flap hinge brackets of the right flap and match-drilled the holes that will hold the two bracket pairs together. Then I started disassembling the right flap so I could debur those new holes, and I started on some of the dimpling that I could easily accomplish with my hand squeezer.
What's next? I'll probably need cut and assemble some wood sleds for my DRDT2 dimpler in order to safely dimple the holes in these flap skins soon.
