I've been puzzling over how to create a neat join between the seat edge and the door frame and how to link this in with the panelling that will cover the fuselage sides inside the baggage compartment. Today I finally made some progress on this. First a piece of 0.050" thick aluminium sheet was cut out and riveted to the left seat panel in a similar way to the rudder cable cover -

An equivalent piece was also riveted into place on the right side. Next a piece of 0.025" aluminium was folded into a "U" shape to fit the gap from the fuselage cross member up to the level of the bottom of the rear window. This is a wedge shape as the fuselage is wider at the top than the bottom but the seats are upright and requires various cut-outs to clear the fuselage tubing. The top front and edges were folded over and riveted to make box structure and the inside edge of the piece was left long enough to protrude behind the seat back and will form the front edge of the mount for the baggage compartment left wall. The bottom edge of the piece is secured behind the filler panel riveted to the floor panel. The top was screwed to a tab welded to the door post. Next another piece of 0.025" aluminium sheet was folded to form the rear window sill and the top mount for the baggage compartment side wall. This will screw to the inside of the window and side panel along it's outer edge and the top box of the previously made section. This will eventually require cut-outs to allow the aileron and flap push-rods to pass through to their respective control horns but by spacing the baggage side wall away from the fuselage covering will
protect the controls from the baggage.
