Bill,
It just came to me what your talking about after reading the response
from Barry.... I have observed the Lancair build shop close out no less
than 8 elevators. Here's the deal.... The ends come fat or the correct
height...(how ever you want to look at it), the main spar is comes low,
in the build shop on the 8 elevators I've seen closed they simply glue a
small wood shim piece Apx every 5" along the spar (they cut up a paint
stir stick to Apx 3/8x3/4x1/8 thick) The epoxy flox was mounded over the
top along with other areas then closed like the plans show.
I did the same thing to mine except I used small cutup pieces of glass
left over from making other parts.
Wont help you Bill but may help others.  I agree with Barry.... Your fix
is a buildup using micro.

Bill,
I've had difficulty interpreting your photograph, but your description
is similar to a problem that I have with my horiz stab and elevator not
matching at their relative distal extremities.  (Lancair IV-P, started
in 2002 at the Builders' Assist.)  I had ascribed it to over clamping
the main portion of the elevator when it was closed out at the Builders
Assist.  The result is a depression in the neck of the elevator (just
inboard of the weight) and a ballooning of the area where the weight is
located.
I think that the horizontal stabilizer is also distorted at the outboard
end.
I talked this over with Lancair.  (I don't remember who I talked with.)
They said, in essence, "They're all like that.  But it's really not
aerodynamically important."  I've seen a lot of IV's and I don't think
any are like that when they are finished.
I had resolved to grind down high spots (around the counter weights),
reinforce the weakened carbon fiber and micro the low spots (close to
1/4 inch.) in both the elevator and the horizontal stab to make them
match and not have a "dip" in the middle.  Looks to me like a really
thick layer of micro (up to 1/4 inch) will be needed.
I haven't tackled that task yet, 'cause I was hoping someone would find
(and teach me) a better way.
