I'm facing the task of attaching the wing center section to the
fuselage on my 320 SFB.  I've had the center section in place, checked
and corrected all levels and alignments, and am now facing the job of
gluing it in place.  The manual says to use Hysol on the glass-to-glass
bond lines and forward load transfer pad (main spar), and micro on the
foam pads.  My problem is that the forward glass-to-glass bond line,
where the fuselage bottom overlaps the underside of the main spar,
causes a very tight fit for the forward spar.  To get it in place the
aft end of the center section has to be raised while the main spar is
tucked under the fuselage bottom (remember, everything is up-side-down),
then lowered while the spar cap slides forward on the load transfer
pads.  Works fine, but if the load transfer pad and the spar cap have
had Hysol applied, this motion will wipe the surface clean.  Once the
center section is in place it is so tight there is no chance of raising
it to create a gap above the load transfer pad to work Hysol into place.
Can anyone who remembers having attached their center section offer
suggestions or comments about how they managed it?
