If you go to post #27, you'll see that the wing's bottom trailing edge pinned on top of the plans. The trailing edge of the wing ribs are glued to the top of the trailing edge. There is shadowing in the pic that sort of makes it appear that there is a rabbet on the bottom trailing edge of the wing ribs, but there is not.
If you go to post #114 (page #8) you'll see pics of the 1/16" cap strips in place that stretch from the leading edge sheeting to the trailing edge sheeting. Same for the top of the wing - leading and trailing edge sheeting on top of the ribs, cap strips between.
I didn't chamfer the top trailing edge sheet (on the bottom) because I did not want the trailing edge to be too thin. This ain't a speed demon...
