Today I repeated everything for the left longeron. I started drilling and clecoing at the tailcone and worked up to the F704 bulkhead. The compressor was given a rest again while I clamped the forward section of the longeron to the side skin. The forward section of the longeron was then drilled using the holes in the side skin as a guide.
