Great Planes ESP6 Easy Sport 60 - GPMA0152 - Manual (Page 16)

D 3. Drill a 1/8" hole at the punch mark on rib #1A.
D 4. Center rib #1A against the LE and on the line drawn
on the 1/8" ply wing joiner. Make sure that rib #1A is
centered between the edges of the ply wing joiner. Using
the hole through rib #1A as a guide, drill a 1/8" hole,
perpendicular to rib #1A, 5/8" deep into the LE.
D 5. Starting at step 2, repeat for the left wing panel.
D 6. On the Easy Sport 60, align rib #1A on the right
wing panel and insert the 1/8" x 1" alignment dowel
through rib #1A and into the LE. At this point test fit the
left and right wing panels together "dry" (NO GLUE) on
the Easy Sport 40 and 60. With the center of the wing
resting on the work surface, block up both wing tips 1"
(1-7/64" on the Easy Sport 60) as measured from the
work surface to the bottom of rib #7 (rib #6 on the
Easy Sport 60). Check the fit of the LE, spars and TE to
make sure they meet up nicely without any gaps or
sweep in the wing.
NOTE: Take your time to make sure that this procedure
is done accurately. A little extra work and attention to
detail here will insure a strong, straight wing.
D 7. IMPORTANT: Do not use epoxy with a working
time of less than 30 minutes for this step! Place
waxed paper on the work surface and mix up some
epoxy. On the Easy Sport 40, apply it to the spar
joiners, spar ends and the ends of both leading and
trailing edges. On the Easy Sport 60, apply epoxy to the
spar joiners, spar ends, the ends of both leading and
trailing edges, the 1/8" hole in the leading edges and the
aft edge of rib #1 A where it contacts the ply wing joiner.
On both the Easy Sport 40 and 60, slide the spar joiners
into the right wing panel first. Slide the left wing panel
into place and wipe off any excess epoxy. Immediately
proceed to the next step.
D 8. Block up the tips of both wing panels 1" on the
Easy Sport 40 (1-7/64" on the Easy Sport 60) as
measured from the work surface to the bottom of rib #7
(rib #6 on the Easy Sport 60). Carefully align the spars,
LE and TE of both wing panels. Clamp the spar joiners
to the spars and wipe off any excess epoxy with a paper
towel. Allow the epoxy to fully cure before disturbing
the wing and removing the clamps.
