Brief Description: deburred and riveted bottom skin
with fuselage elevated on concrete blocks, reached under the center section and drilled the overlap of fuselage skin over center section skin. Removed all clecoes on that skin, deburrred all holes, reattached skin. Riveted the center section overlap, and also riveted all the bottom sectors at each bulkhead. Left the upper edge of the skin free to allow for placing longeron and/or skin flange. Also noted that there may be a slight twist in a counter-clockwise direction when standing at the tail and looking forward. At this early stage it should be possible to correct that twist, but need to do that next before any more riveting.
