Listers,
While installing my leading edge on the left wing, it seems like the
skin of the leading edge is overlapping the top main skin by about
1/32". Talking to VAN's, they suggested that I check to see if the wing
is twisted at all. Does anyone have any wise words as to how to check
for wing twist and if there is any, how to remove it? Is there any twist
that should be there?

Is the overlap the same the whole length of the leading edge skin, or
just at one end. If just at one end, then there could be a twist.
There is not supposed to be any twist in the wing. We have seen
periodically that the leading edge skin needs to be filed a little bit
to nest in with the rear skin. The biggest thing is to make sure that
there is no twist, which you should be able to see by looking down the
plane of the skin from one end, then just file a little bit off.

Ed;
Did Vans say there is any twist designed in the wing? I'd ask that
question. I don't think there is.
Did the other panels line up correctly? Did you have to force any rivet
lines ?
Just a thought. Set it up on saw horses so that the Main spar is
plumb. (inboard side) . Then get a board and place it vertical at the
outboard edge with a plumb line on it. Then get a couple laser pointers
and shoot a line down the upper and lower line of rivets.
Second thought. Do you know what winding sticks are? Basically,
couple of straight sticks. Tape one on the inboard and one on the out
board part of the spar. Then sight down the top of the sticks and see if
you can see any twist in the spar.
If I had a twisted spar, I think that would not be something that I
would want to "fix" other than consideration of replacement.

Jesse,
It seems that at the outboard end, that the skin will lay flat
against the spar flange, but when you get in a couple rivets, it starts
the overlap. Also, looking through come of the inboard holes, it seems
like the holes off by about the same distance as the overlap. Because of
that, I am thinking of removing the rivets that I have installed on spar
web to ribs and rivet the LE skin first, then the spar.

Ed,
You may want to temporarily cleco that wing's bottom skins on, then see how the leading edge lines up. It will provide additional defined positioning of the outboard spar. How do the rivet lines of the top skin and leading edge compare when installed?

Fred,
No, Van's did not mention anything about a twist that should be in
the wing, just to check if there was any. I was asking because of
something else that I had read that mentioned about a twist from the
wing root outward, but that was not for a 10. Thanks for the insight on
checking. I will set the wing up and check it out. The only skin that I
have riveted so far are the top wing skins and they did not show any
problem.

Sean,
Checking the alignment on the holes in the LE to the holes in the
spar, it seems that they are not exactly lined up either and they are
off by about the same as the overlap. I did a test fit of the LE to the
top skin on the right wing and it is tight, but there does not seem to
be an overlap. I will try it with the bottom skin to see what that shows
me. Thanks.
