Trailing edges

Hours: 1.5 | Posted in Elevators, Rudder

Bought a couple 8′ pieces of aluminum angle from Menards the other day, so I got the trailing edges sealed.  Using the severely expired Proseal (exp. 11/07) might not have been the best idea…I had kept the tube in the fridge since receiving it, and it warmed up just fine, but the mixing head broke off the “dasher rod” when I tried to mix it.  I squeezed it all out onto a piece of cardboard for manual mixing, but it took a very lumpy/ropy consistency when mixed.  It was still quite sticky, so I used it by scraping off the lumps…hopefully it will work.  This validates my decision to NOT order the Proseal for the fuel tanks with the wing kit.  I’m not worried, since Van’s sells expired Proseal at a discount, with a note that it’ll be fine for this sort of application, but not recommended for fuel tanks.

In any event…the empennage trailing edges are clecoed to angle, awaiting the cure of the Proseal before starting to rivet.  I plan to use an angled set in the squeezer to do these, and will experiment on the practice kit first.
