The first (picture 1) is the wing tip rib. Three rivets and its on.
The second (picture 2) is riveting of the Hand Hold to the end of the main spar. Another three rivets. I had previously formed the two 90-degree bends around a block of wood with one of the edges radiused on the scotchbrite wheel.
The third is riveting of the Wing Tip Bottom Skin. Picture 3 shot from underneath the workbench looking upwards. To do this I had to pull the wing tip off the end of the bench so that I could get access to the underside. Of course the weather gods decreed that it would rain at this point, just when I needed to stick my bum outside as the garage is not long enough to do things at the end of my workbench. Again note the holes that should not be riveted at this stage.
