May 7th Update - Mid Fuse Lower Structure

Big day of work.  I clamped the F-01404 Bulkhead assembly with seat ribs to bench vertically, and attached the center bottom skin with clecos.  Then with Kathy's help, riveted the center bottom skin to the assembly.  After this, riveted the gear brace assembly to seat ribs per section 26-15, and the power outlet bracket.  Finally, assembled the step attach weldments to the baggage ribs and completed both sides - attached with clecos to the seat rib/bulkhead/skin assembly - ready for riveting.   Long day, big progress.
