Turned left wing over, blocked on to 2 x 4 checked for level and using the 13mm block and level to check washout and clamped in place. Installed U-14 stringers riveted in place after deburring, dimpling, using 412 rivets. Laid bottom skin for under fuel tank and laid out rivet line and drilled and clecoed in place. Then clamped rest of bottom skin in place and drilled and clecoed after trimming both sheets to size. Now I only have all the rest of the holes to drill.
