Brief Description: Started work on the left bottom main skin.
Today, while I wait for new aluminum to put on the last top skin of the right wing, I began work on the left main bottom skin. I began by rough cutting a 12' x 4' sheet. I then clamped it to the skeleton (measuring VERY carefully the trailing edge). I then marked the aft rib location through the lightening holes. Next I un-clecoed the nose rib skins and reached through the front lightening holes and marked the rib locations there on the bottom skin. I then removed the skin in preparation for marking and predrilling.
