Now that the skins have their stiffeners, it is time to build up the skeleton for the elevators. The first step is to cleco and match drill the reinforcement plates to the spar. These reinforcement plates are where hardware will be bolted to connect the elevators to the horizontal stabilizer. Next, the end rib is clecoed and match drilled to the spar. this intersection is where the elevator horn is riveted to the elevator. This horn will control the movement of the elevator.
Once the skeleton is together, the skin can be clecoed and match drilled to the spar. Then the counterbalance arms are clecoed together, and those are added to the structure and match drilled.
