"Worked on fitting forward and aft ribs numbers 7 8 and 9 on the right main spar. Aligned the spars to fit as shown in Detail ""K"" of drawing W14. Made a template using a metal yard stick. Screwed the template to the side of the work table. Clamped into place on the spar the forward and aft rib individually and determined the needed alignment. Then clamped the ribs to the template with the appropriate adjustment and drilled the holes to match the spar holes (#40). Then clecoed both ribs in position and drilled the holes to #40 then 1/8th and then #30. Removed the clecos and check to be sure the holes were acceptable in shape and size."
