Mounted aileron blocks on Spar 7. Marked channel, cut to size, drilled and clecoed in place. Cut 'L' doublers for Spars 1,2,3,4. Cut 'L' brackets for wing locker Spar 4 & 5. Couldn't find 6 2x2x5' steel stock. Ripped a couple of 2x6's to exactly 2" instead. Used pressure treated lumber, so hopefully they won't warp.
