Wing skins

The kit instructions call for putting together three parallel 3x22 inch 1/16th balsa sheets for each skin. However, I must have cannibalized some of those sheets way back when, and have only five instead of twelve -- though I also have some other very good 3x48 balsa sheets from the same period I'd like to use. Also, one of the five sheets weighs about 25g, while the other four only weigh about 17g. After a little creative thinking, I decided to go with putting one sheet parallel to the leading edge (using up the four matched original sheets), another sheet parallel to the trailing edge (from my other old balsa supply) and using the leftover super-stiff but heavy sheet for the little triangular section left in the middle. I put the sheets together using slow set CA glue directly on their edges and holding them together flat over wax paper for assembly.

I forgot to take pictures of the total weights, but each pair of skins ended up within a gram of the other this way.
