Spent the day prepaing flap parts. Made both left and right drive plates first since these were pretty simple. Next was cutting the skin to lenght and with the proper angles on the the inboard side. I also made a drill guide for the top and bottom rib holes from the scraps from the cut off pieces. This helped speed up the layout, marking and drilling. Just line up the guide on the rib line, tape it down and drill. Too easy.
