I headed down to Scaled this morning around 10:30 AM.  The layups from yesterday had cured so I trimmed them. I then cut some foam to fit in the space between the lower winglet and the wing and 5-min. epoxied it in place. After sanding it flush, the lower winglet was ready for glassing.

I cut the 2 UNI for the winglet, micro'd the surface, and applied the glass, wrapping around the leading edge and bottom (inverted). I left the last 3 inches of the fishtail side unglassed, and will have to finish that after trimming and sanding tomorrow. After peel-plying the whole winglet, I flipped the wing right side up.

I then sanded the foam for the top wing surface flush, and roughed up the TE glass. I cut a piece of nylaflow for to patch the hidden belhorn conduit and then heat shrunk it in place to either side of the damaged conduit. I then used toothpicks to hold the conduit in place in the foam.

After cutting glass (2 UNI) for the top wing/aileron skin, I micro'd, glassed and peel-ply'd them.

Done for the day - I don't think I'll be done tomorrow - I've still got at least one more layup on the winglet TE, and then a closeout where the lower winglet meets the rudder. I'll be able to micro everything except the winglet TE tomorrow, though.

Getting there......
