Continued work on the floor ribs. Drilled this morning the F-815 ribs on the left side. Tonight continued to finish drill the ribs to F-806 bulkhead. Deburred all the ribs and checked all the components for deburring and ready for prep and alodine. Still need to drill F-815 to F-806 bulkhead and the F-806E. Then I need to drill the F-814EPP to F-804 D angle bracket.
