Final update for the day:
Fuse is "framed up", so to speak...F1 is installed, and the tail end is glued together, and sanded to round. F1 shouldn't be going anywhere...Glued into the fuse sides, triangle stock behind it, and then pinned with 3 2" long 1/8" dowels on each side. All glue is Titebond III.
Inside joints of fuse sides to F1:
F1 seen from the front:
End of the fuse...TE stock added in the inside of the fuse here for some rigidity, and a larger gluing surface:
The fuselage as it sits tonight:
