1. With my right elevator mounted to the HS, the gap between the HS
skin and the elevator counterbalance skin is about 3/32-4/32. What is
the proper gap? I can't see where it says in the plans. The good
thing is that this gap is, by and large, consistent where those two
surfaces come together.
2. More problematically, when mounting my left elevator, I noticed
that this gap ranges from about 3/32" at the aft portion of the
counterbalance arm to only 1/32 between the forward tip of the c-b
skin and the HS. This is not the result of different rod-end bearing
settings, but rather that the forward part of the counterweight
balance skin on the left elevator cants (sp?) inboard about 2/32"
toward the HS and away from the outboard edge of the main left
elevator skin (in other words, visualize a line extended straight
forward in line with the outboard edge of main elevator skin--my
counterbalance arm angles inward from that imaginary line). I don't
know how this happened, as I had the ribs fluted dead-on straight
before that skin when on (and were much straighter that my right
elevator c-b ribs!).
I don't think I can make up this by setting different rod-end bearing
distances. Either I'm going to have to do some pretty heavy shaving
on the front inboard portion of the counterbalance skin, or I'm going
to have to somehow straighten that counterbalance arm to make it line
up better with the main elevator skin and HS skin (perhaps by taking
out the entire line of rivets going down the main skin on that
outboard rib and couterbalance arm).
Has anyone else had this issue (either a clearance issue or a
counterbalance skin that is not in line with the rest of the
elevator?) and how did you solve it?
Thanks,
Steve

Don't change anything until you install the fiberglass tips. They will
change the geometry of the counterbalance arms slightly.
