Centuri Skylab Build, #KB-4, Part 15, Skinning The Fins & Fin Gluing

As it turns out, the fins are too thin for a friction fit in the support slots.  I'll need to laminate some cardstock to increase the thickness.

The mat board fins had the leading edge rounded for a smoother "fold-over" of the cardstock skin.

The 110 lb. cardstock was cut oversize.

The outside layer will be "butterflied" with the fold rolling over the leading edge. Score and pre-fold the leading edge.

I used a glue stick to adhere the skin.

Set the folded edge first over the rounded leading edge.

After skinning the two fins - 

The 3" long launch lug tubes are glued to the outside edge of the fins.

The two square solar panel fins and smaller pod supports are glued on.
