And today I read in a website as a builder fumed and groused over the
asymmetry in his RV kit.

Which brings me to the present subject of rebuilding two Cessna flaps. I
clecoed the trailing edge of one of the flaps together last night after
having drilled and deburred (whew!) all the new holes with the flaps in

the

jig built here in the shop. All I could say was "Yuck. Pitiful." The
trailing edges looked like an attempt at a straight line by a drunk when I
sighted down them. Take note that I clecoed them together AFTER they were
out of the jig. Of course the jig, made of straight-and-true aluminum

angle

gently but firmly squeezing both sides of the flap near the trailing edge,
will make it true when it is riveted together. Theoretically. And so I

am

promised.



The trailing edges of all control surfaces on RV's are bent, not riveted.
On ailerons, elevators, and rudder, the skin is one large V-shaped panel, to
which you attach a spar, end ribs, and some stiffeners, and then bend the
front around to a rounded shape and pop-rivet it.

The new stuff is riveted at the trailing edge. I just built a new rudder
and vertical stab for my RV-6 and used the two piece rudder skins
riveted together at the trailing edge. Wow!! that pre punched stuff is
really nice, every hole lined up perfectly.
