1: Since the flap actuator rods go right through a big holes in the floor, I want to prevent too much cold air from getting in. I began construction of a pair of boots for the flap rods. Each one will be made from a foam painter's brush, with a capture plate made of scrap aluminum. The rods will slide through holes in the foam.
2. To speed up the final assembly of the airplane later on, I have begun running a tap through all the painted nutplates in the floorboards, side panel pieces, and any other interior piece containing a nutplate. Today, I did all the baggage compartment pieces, along with the aft floorboards.
