Brief Description: Match-drilled and countersunk holes
Completed match-drilling the #30 and #11 holes into the Center Section Assembly. Disassembled the pieces and deburred the holes. Countersunk 13 holes in the Assembly and then dimpled the corresponding holes in the F-1204D Center Section Aft Bulkhead. Deburred the F-1204F Left & Right Aft Side Bulkheads. Hopefully, I can prime the parts tomorrow.
