Riveted left attach strip to bottom rib. Had lots of trouble with aftmost rivet, used "indirect" technique that I saw on an EAA video. Blind riveted bottom edge of bottom rib, twice. Was initially positioned below 904A-1 (wrong), Drilled out and did it again. Added brace horn, was not able to set the AN470D4-6 rivets. Ordered a longeron yoke for my squeezer. Continued on with riveting skins to brace and bottom rib, the top ris. Added counterweght, torqued to specs. Riveted skins to spar. Installed top rib and riveted.
