Greg,
I find that measuring the wing skin thickness and using spacers to be
the idea way to set the wing incidence when using the incidence board.
You will notice that the wing skin has about a 1/4 inch of foam but that
foam ends before the root rib. The skin is about 6 layers thick at the
root or about a popsicle stick. The big thing is to get both wings the
same. Get anal about it and use a good digital level, the same
incidence board, a spacer set about 2 inches in front of where the rear
pin goes, and I even hold the level with the digital screen facing the
same way at the same exact position on the incidence board. Then,
before I glue it final, I step back and check by eye, the lower skin of
each wing of the aircraft from behind to verify that the bottom of the
wings both are at the same angle. See my website for trimming the
Europa.

Subject: Europa-List: Should top wing skin be simulated when bonding
on wing-profile jig
<gregoryf.flyboy@comcast.net<mailto:gregoryf.flyboy@comcast.net>>
To Any/All builders,
Before bonding the wing profile jig on the upper part of the wing
(when
installing flaps on the wings), is it assumed that the upper wing skin
thickness should simulated with a suitable spacer such as popsicle
sticks or
such? The jig, when placed on the wing root, lines up with the
indentation
where the top wing skin would be, at the rear of the wing. I placed
lately
taped-in sticks at the rear of the wing, where the jig will be set, to
simulate the top skin, in anticipation. The difference between both
ways is
only in the 1-2 mm area, but anyhoo.. Including spacers looks like it
would
-slightly- increase the reflex of the flap. Just trying to get a feel
for
what others have done, or interpreted this move. A short search on
matronics
did not eek out any results.
Thanks in advance,
Greg
