The four main assemblies of the front of the Fuselage were riveted together and clecoed onto the front floor panel F-822. The remaining structures were assembled on to it with clecos in order to determine what goes where and what will need machine dimpling or just dimpling etc. It's a huge jigsaw puzzle! Before the parts are primed or corrosion treated it was important that all the preparation of holes and dimpling is complete. The instructions often call for the optional priming of parts only to call for more dimpling or drilling in a later chapter; it required future chapters to be constantly read before completing the assembly of an earlier chapter.ly of an earlier chapter.
