Being an off Friday, I headed down to Scaled to work on my wing around 9:30 AM. Although there was a lot of activity (folks getting overtime), I was able to commandeer a table, haul my wing out, and continue repairs.

First I sanded down the foam on the bottom wing skin and aileron, including the bottom of the fishtail area. I also pulled out my hidden rudder belhorn and cut away foam and glass where needed to ensure full motion of the belhorn should I ever install it. I made sure that the conduit had room to move within the wingtip.

I then cut out the 7 plies of UNI I would use to patch the hole in the wing/winglet joint layup, as well as 2 plies for the lower wing skin/aileron skin.

Next, I micro'd the exposed foam and applied all the glass (using Pro-Set with the slow hardener). I peel-plied everything EXCEPT where the lower winglet would attach. I then micro'd the lower winglet in place over the 7 ply UNI patch and held it in place with taped mixing sticks.

I put a heat lamp over the layups and left for the day - 5 more hours of work, and I think I've only got one more day of layups to go. I might be done by the end of the weekend if I'm lucky......

 

I've sanded the foam to match the countour of the lower wing skin, including the fishtail bottom

The 7 UNI structural layup is in place over the hole, and the micro has been applied to the bare foam

The lower skin is glassed and the peel ply applied everywhere except over the lower winglet core join area

The lower winglet core is micro'd in place - from the inside

The lower winglet core is micro'd in place - from the outside
