This brief work session focused on preparing the ribs for the Horizontal Stabilizer. The first step was to match-drill some new rivet holes in the nose ribs and the inner ribs, using the spar as a template. The instructions specifically say to match-drill those two parts (nose and inner rib) individually, however I didn't see that note and attempted to drill them while they were both clecoed to the spar together. This unfortunately resulted in not having the HS-1004 inner ribs clecoed flush when match drilling, so their single center holes got slightly offset and then oblong-shaped when I tried to properly re-drill them. While contemplating my options and whether I needed to order two replacement HS-1004 ribs, I realized that I could simply swap those badly drilled ribs for the other positions where the HS-1004 is used since they don't need the center hole there. I marked these bad holes with a "X" on their flanges, as seen in the right stack in the photo. After puzzling over the intentions of the instructions for a while, I carefully marked all of the holes that didn't need dimpling and used the hand-squeezer to dimple the holes that needed it. In other good news, I was able to borrow the H-stab cradles from Tyson, another RV-14 builder from my local EAA chapter, saving me probably a couple of hours of effort to manufacturing those single-use jigs. What's next? Start preparing the skin for dimpling.
