Chapter 19 – Final prep for top wing skin

Well, I finally finished removing the peel ply from the TE.  I then finished cleaning it up.

I sanded most of the Inboard spar cap area, including around the aluminum wing bolt extrusions.  Specifically, there’s a 1″ strip of glass between the Outboard extrusion & the side of the front of wing jut-out (BL 55.5) that was pretty rough & needed some tough love. I sanded it down & got it fairly smoothed out in that 1″ strip.  It needs to be smooth since the rib that gets glassed into the front of wing BL 55.5 jut-out will overlap onto this surface. I also cleaned up the aluminum extrusion faces & the wing bolt access overhang piece (W18).

I installed the NAV2 VOR antenna by running the cable into the foam & down into the wing wiring channel.

(both of my Inboard FC4 pieces were rounded over just a bit for about 4″, so I just want to the glass to come straight out and not follow the roundover… which is only about .1-.2″ deep)

I tacked on the 1″ x 65″ peel ply at the aileron junction (again, on the wing side).

The final large UNI layup on the wing is 1 ply of UNI that goes from the Inboard side straight out to the tip of the wing.  This starts above the aileron & follows the top edge of the aileron at the aft side of this layup.  So, I marked a spot at 5.9″ from the TE at BL 55.5 & put a spot at 4.35″ up from the TE at BL 106.25 to mark the aft UNI edge of this layup.  Now, there are a few other smaller layups that get glassed, but this is the last really big one.
