Chapter 19 – Skinning Left Wing

I started out today by vacuuming the entire top of the wing.

I also refilled my slow hardener bottles & restocked my blue glove supply.

I used a 50:50 slow/fast for the thick micro on the deep fill areas.  I used wet flox on the TE & 70:30 micro/flox on the LE.  I used 80:20 slow/fast microslurry for the foam fields.

My buddy Kevin helped me by working the epoxy station, and he also helped layup some of the glass as well.

After I got the foam all micro’d, I laid up the wing UNI glass that I had pre-cut.

I peel plied the Outboard extrusion area “V” that borders each side of the wing bolt access hole.  I also peel plied the front face of the extrusion (LWA3).

I laid up the 14″, 10″, 6″ plies of UNI over the Inboard extrusion/wing bolt hardpoint & overlapping up onto the wing (just like the Right wing).

I laid up the triangular ply of BID reinforcement on Outboard end of the wing & peel plied it.

I clamped & clothes-pinned an aluminum L-bracket–lined with duct tape–to the TE to keep it as straight as possible as it cures.

I came back to check the layup about an hour later.  I had a couple of quarter sized bubbles that had developed right at the front edge of the spar cap.  I worked those out & re-checked the entire wing layup.  Everything looked good!
