Thank's Steve,
I had read about the trued face (down side) of the shuck, what
threw me off was no left or right panel. I kept thinking of down
as the bottom of the wing, when in fact down is only the bottom
of the wing for one side.

The DOWN marking on the shuck is very important.
The DOWN side on the foam shucks is the side the goes DOWN when the foam parts are curing under weight.
When the foam cores are cut they true one side of the shucks so it is flat. You put that side down so as not to impart
any warp into the core you are sheeting.
Steve
