29 - Fwd Mid Fuse Side Structure (finished right side; seat back brace)

Slow yet steady progress during this past week and a half.  Most of this time was spent finishing the right side of the fuselage, and while I didn't take as many pictures this time (since the right side is almost an exact mirror of the left), I specifically accomplished the following:

- started right side skin - attached to upper & lower longerons, stiffener, and (temp.) bolted longerons to firewall
- clecoed and match-drilled skin/firewall and right side shim (and deburred and dimpled); final drilled all #30 holes common to skin and longerons; final-drilled holes common to skin/center section/ upper drag fitting (and deburred); broke edges of right side skin; radiused top edge of skin; feathered upper aft corner of skin; dimpled right side skin; deburred edges of vent and other cutouts
- countersunk and re-primed countersunk holes in right longerons; riveted right roll bar angle to intercostal; riveted fuselage side ribs to skin; riveted drag fitting and center section side plate to skin; riveted stiffener to skin; installed skin to fuselage; bolted upper and lower longerons (temp) to bulkhead
- prepped stiffeners and other bits for the right side skin structure; riveted canopy latch brackets to side skin; prosealed and clecoed right skin to firewall and right upper longeron
started riveting right side skin to the fuselage, ribs, stiffeners, etc. (used back-rivet bucking bar for as much as possible)
- almost finished riveting right side skin and associated parts to fuselage assembly
- Finished riveting right side skin except for 23 rivets common to the bottom skin; Riveted web stiffeners to bulkhead assemblies; riveted nutplates to center right bottom skin and root fairing attach angles; riveted root fairing attach angles to right side skin; reinstalled bulkhead bar assembly (right)
- fabricated seat back adjustment guides, and assembled seat back brace

Temporarily attached the right skin to match-drill a few holes in the engine mount brackets:



Re-primed the upper and lower right longerons:


Back-riveted the upper drag fitting and center section plate to the right side skin:


Magically, most of the riveting of the right side skin to various fuselage components was finished:

Attached flap block bracket:
