The main criteria for these side screens was that they had to be made with the tools I either owned or had easy access to. It’s all pretty common stuff like saws, drills, propane torch, measuring tape, taps, riveters, and things of that nature. The second criteria was that when finished, they needed to represent a style that would not look out of place on a Cobra. Two pictures that inspired me to proceed with my intended design direction are shown here:
Notice that in the top photo there is a simple panel that slides in a track to allow access/ventilation, etc a la Daytona coupe. There’s no access panel in the screen shown in the second photo, but rather an Aircraft window “snap vent” for ventilation and some sort of extension on the interior door latch accessible through a small hole in the screen for opening the door. I chose to go the direction of the top photo.
