November 29, 2016: aft fuselage parts prep, riveting right elevator & trailing edge
Began parts prep for Aft Fuselage. Found some damage to one of the fuselage skins that I missed during the inventory/inspection. Email to Van's about this - pending a response. Completed riveting all skins on right elevator, and riveted the right elevator trailing edge. Looks very good and straight. I continue to get better at this technique - just in time to be done of course.

November 28, 2016: left elevator trim motor completed, elevator counterweights
Installed and tested trim motor assembly in left elevator. I had to "flip" the trim pushrod - drawings are confusing. Not a big deal. Connected the wiring harness before install - used a 9v battery to test. After this I used the battery to align the trim tab with elevator trailing edge. I completed riveting the rolled leading edge of the elevator. Also begain working on the counterweights for both elevators. Made a mistake in trimming two of these - ordered new ones. I struggled to trim excess material from the counterweights (required for one on each elevator). Finally "discovered" a technique using putty knife. I put a post on Van's Air Force about this: http://www.vansairforce.com/community/showthread.php?t=144412

Completed most riveting of right elevator, installed foam ribs and trailing edge using proseal, clecoed trailing edge, and placed with weighted board for a few days for proseal to cure. Completed additional work on left elevator including connecting molex connector on the trim motor and rolling leading edge - clecos placed.

November 20, 2016: right elevator parts prep, priming, complete riveting left elevator
Completed prep and primed all parts for right elevator. Completed riveting of left elevator including trailing edge and close out tab. Completed sections 9-14, -15, -16 for right elevator. Using MK-319-BS rivets for attaching skins to rear spar, much easier and less bending of skins than using the special bucking bar. Ordered more to have adequate quantity. Also ordered more 3-3 rivets for skin to ribs (not enough to completed bottom and top skin back-riveting. |

Long day of work.
Completed Section 9-2. Final drilled elevator tip assemblies. Completed Section 9-4. Bent close-out tabs on skins and drilled the pilot holes in trim tab hinges. Completed Section 9-5 - for left elevator only. Error at this point - I drilled 5/8 hole in wrong place on one elevator spar.

November 16, 2016 update: Horizontal stabilizer completed
Horizontal Stablizer is completed as of today.
Yesterday:
Substantially
completed Section 8-12. Riveted ribs
to rear spar (with universal head rivets and blind rivets) and skin to rear
spar. Max B here helping me. One rivet (rear spar to inspar rib) had to
be drilled out. Hole was sl oversized
so I used a CherryMax rivet (drilled to #27 by design) to replace it. Turned out very nice. Also replaced the two rivets on VS drilled
out with Vic Syracuse's help with same size CherryMax rivets. These are a good solution where a 1/8"
hole is sl oversized. Today: Max helped me do the last 10 rivets (front spar to inspar nose ribs). Section 8 is complete! |
