Drilled F-633 Control Column mounts per instructions and then cut away extra material per drawing and polished edges. Decided to hold off on assembling the control column and stick bases until ready to prime all components. Countersunk and riveted all nutplates to 704A&B. Prepared the 782B and 783B Cover Support Ribs and drilled them to bulkhead. Began riveting nutplates onto them. Fabricated the F-704M Web Stiffeners from angle stock and drilled to 704A.
