Glassing wing top surfaces

The fiberglass on the bottom of the wings cured overnight.  The wings were removed from the wing fixtures and placed top-side up on sawhorses.  Any overhanging fiberglass was cut off with a sharp blade.  The trailing edge foam was trimmed and removed using a knife and a long steel straightedge to expose some bottom glass for the top glass to bond to – this surface was sanded well. All other edges were sanded to remove sharps.  The foam was sanded to make the surface smooth and any excess micro was ground away.  A trench was melted into the foam with a soldering gun for the rudder cable, running from the wing root to the tip.  The Nylaflo housing was inserted and hot-glued into the trench. The foam was rough-contoured on the wingtip, and a cutout was made for the rudder horn cove.  A pre-fab cove part was microed into place with the rudder cable housing passing through it.

The top-side aileron seams were taped to prevent the glass from sticking, and then the wings were filled and faired with micro.  Then cabo was used to do a final fill and wet of the spar and non-foam pieces.  Triax fiberglass was cut, draped, and wet out on the wing top surfaces.
