I'm skipping ahead and assembling the trim tab first.

Sections 61-71 do not mention drilling out the hinge line holes or the
trailing edge holes, but near the end it says to rivet the trailing edge.
Up to now the instructions basically lead you by the hand, but the
trim tab instructions could be improved. Fortunately it is not a
difficult part, but even so...

Did you know that blind "pop" rivets come in the flush variety? I didn't, and
there are a few places that you can't use a driven rivet. Someone mentioned
the flush blind rivets at the EAA Regional flyin in VA, so I spent some time
tracking them down. Most of them are 120 degree, not 100 degree. After trying
for several days to find 100 degree, I gave up, ordered the 120 degree, and
a simple 120 degree dimpler that works in a pop rivet gun.

Finished up the trim tab. I used structural blind rivets for most of the rib
rivets, and a squeezer with driven rivets for the rest. The epoxy trick and
clamping the trailing edge to a piece of angle iron worked well here, as it
did on the rudder. Nice straight trailing edge.

Elevator Assembly.

I've decided to go with the electric trim option. Fortunately the only thing I
had to re-do was the cutout for the trim cable since the electric trim control
arm is in a different spot. I'll probably build a small cover to close up the
hole in the skin where the manual trim cable was supposed to pass through the
bottom of the elevator.

Cut-out for electric trim option. Top skins on the elevator.
Finished up the tip ribs, and marked the cutout in the top skin for
the electric trim servo.

Clean, deburr, dimple, prime, assemble elevator framework and upper skins.
I had already started installing the manual trim system, and made the cutouts
in the bottom skins for the cables. Since the cut-out for the electric trim
system is different (smaller), I decided to make a small plate to cover up
the excess. You can see it in the first picture here.
