Got back to work on the left wing. Repositioned the wing on the table and finished installing the upper rear skin. Drilled to #30 and flipped the wing after marking the required line on the forward edge to locate the leading edge. Installed the leading edge to the lower forward spar and drilled to #40. Drilled the lower leading edge to the forward rids to #40. After making sure all was level, drilled all the lower holes to #30.
