Pre-fuse construction preparation

Building Note: If you are going for a quality build, it’s time to a little pre-assembly preparation.

• Tops of both P-4/B-3 blocks on a side are sanded to ensure that the tops of both are aligned, smooth and true with the edge of the fuse.
• All exposed glued joints of the fuse and doubler are sanded.
• All laser-cut attachment “nipples” are sanded off.
• The inside of the cowl cheeks are sanded smooth because after assembly you cannot effectively finish these surfaces.
• Inside surfaces of the fuse and doubler are sanded (OK, I’m anal on this – just in case I go with transparent covering)
• Edge surfaces of F-1 and F-3 are sanded to eliminate any “nipples” (just being redundant)
• All pin holes created when aligning the fuse & doubler are filled with a finishing resin / micro-balloons putty
• Test fit the cabanes with the mounting blocks.

<edited> I installed the 4-40 blind nuts after the fuse sides had been attached to F-1 and F-3. Note the use of a piece of 1/8" lite ply used to protect the exterior surface of the fuse side when drawing the blind nut tight with the screw.
