After I painted the cowling's inner surfaces white and the paint dried, I riveted the oil door hinge plate to the cowling and installed the oil door. This involved installing a spring to the hinge pin: This spring kicks the door open if the camlocs come unlatched. With the door swung open, I should always see it whenever the oil door is unsecured. Swing check was great.
Image 2 shows the camlocs' initial fit: I remedied the button fit with subtle bending on the camloc button arms. I have to say, I'm not entirely satisfied with their flimsy construction. We'll see how they hold up to real use and abuse.
