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......
