Today I put the side skin in place and trimmed around the main and rear spar attachments. I then marked all the rib / bulkhead / stiffener loactions, removed the skin and layed out the rivet pattern. I pre-drilled all the holes with a #41 and then put the skin back in place. I drilled the skin to the structure. I will drill the appropriate holes out to #30 when I am almost ready to pull and dimple the skin.
