The last part of the fuselage joint, at least the inside work, involved the hatch area up in the nose. This panel will eventually be cut out and turned into a removable access hatch to get to the electro-mechanical equipment that will be installed up there. Or a jacket.
The process here was the same as before. First a single ply across the joint, then some foam core to fill the joint, then 2 plies over the whole mess. The only difference in this area was the use of 1/4″ high density core instead of the 3/4″ core I had be using. I like this 1/4″ stuff better anyway since it’s easier to shape.
After the basic layup was complete, there was an extra step to build and attach 2 stiffening ribs to the inside of the hatch. Since it will be removable, these will allow the hatch to keep its shape. The stiffeners were built out of the same 1/4″ high density foam core, then bonded in place. The edges were rounded off, and the joint radiused with an epoxy micro mixture, then 2 plies of S2 glass were added over the top.
The S2 glass is a special weave that allows it to form nicely over tight areas and compound curves.
Overall, I think the installation came out pretty good. In the below photos, the fuselage is upside-down for the first 3 photos, and upright for the last one.
