Brief Description:  Finishing 101 - aileron and fuselage windows

Over the last week squeegeed 4 coats of raw epoxy of the port aileron top, scraped and sanded it like the bottom. spent ages removing resin blobs from the bottom. Final balance was 66g, which I'm happy with at the moment.

Evolved a method for the window flange. Once I was happy with the feng shui of the window edges, I marked an accurage 3/4" flange and trimmed the excess. I then trued up the flange edges until they were straight, and the corners of a constant radius. I then transferred this profile back to the outer edge with a 3/4" guage, and remarked this edge, and adjusted. All looks good.

Used the same method on the little door over the ballast compartment, and the flange just looks too big. I note that on the rest of the plane, the bigger the window, the smaller a 3/4" flange looks. I grit my teeth and trim the ballast door window back to 1/2", and reckon it looks brilliant.

I note the flange is a little deep. but Silpruf/Sikaflex will make it work.

Discover I can visualise all this a bit better by placing a 3/16" packer against the edge of the window, and seeing how much bond will be under a 1/8" packer placed against it, level with the outer skin. It lives!
