Brief Description: F-705 Bulkhead - Drill Center Lower Section
I lined up the bar on the lower edge the center section. This is the wing rear spar attach point. These bars will eventually pinch on the wing rear spar and be attached. I drew a line down the center of bar, centered the line in the pilot holes, clamped it and drilled it.
First I drilled the center section and clecoed. Then I added the outboard bars and drilled them.
