Bill, Neville told me that trimming 1/8" off the socket is OK. The pin is
not at exactly a right angle to the wing root on mine. A friend is a
engineer/machinist looked at it and we took off .125 at the center at an
angle that gave .150 at the rear and .100 front of socket. Now when I slip
the socket on the pin it mates nice and even to the wing root. However with
the wings set properly I still have a bit pressure on the socket from the
fuse side where I believe we should have a 1mm free space before redux? And
this is since I ground through the four layers of bid on the outside of the
fuse in the shape of the socket base. The pin protrudes only to the alum
plate, the rounded end part is about to the inboard side of the plate. And I
have the four layers of bid on the inside of the fuse. Not at all sure what
to do, Neville? Help!

Kevin,
I am at the same point and am having just about the same problem. I don't
have enough room for the socket to fit between the port wing root and the
fuselage side. I am considering trimming 1/32 to 1/16 off the black
aluminum socket, though I don't like doing this. I don't believe it is a
good idea to trim down any of the glass around the pin in the wing as this
might compromise the strength of the aluminum plate inserted into the root.
Though as I consider it, it might be safe to take a little of the glass from
around the pin if only an area just enough to accept the socket. My port
pin actually protrudes through the fuselage skin slightly into the cockpit.
I have checked for interference inside the spar tunnel and found none. To
get my wings inline with the string stretched tip to tip, I have to pressure
or load the wings forward moving then about 1 to 1 1/2 inch at the tip.
This requires about 5 pounds pressure at the tips. This translates to maybe
4-5 times as much at the rear pin putting it in compression. Andy at Europa
suggests that I pin the two wings together separate from the fuselage to see
if the wings align without any fore or aft sweep. Mine are pretty true.
When I measuring from the forward wing tips to the aft most center of
fuselage (when the angle of incidence and sweep is set) the measurement is
3/8 inch closer on the starboard side. I figure this last dimension is
important but the least important of these settings.
