Machine Countersink, Machine Countersink, Machine Countersink! That was the task for this session. I completed the countersinking on the F-01418B-L and F-01418B-R Longerons to fit the dimpled Side Skins. There were 144 holes in each Longeron for a total off 288 countersunk holes. I will post some pictures of the completed Longerons tomorrow.
I still have some "optional" countersinking to complete because I decided to use flush screws on the F-14112 Plate Covers. I will complete this during the next session.
