Great Planes ESP6 Easy Sport 60 - GPMA0152 - Manual (Page 18)

D 5. Remove the wing dowel from the wing. Mix up a
batch of 30-minute epoxy. Apply the epoxy to the inboard
side of both die-cut 1/8" ply 1B ribs. Install the 1B ribs as
shown on the plans, lining them up with the 1A ribs
(Remember: the embossed "T" identifies the top of the
rib). Quickly pack some epoxy into the wing dowel hole in
the LE and insert the wing dowel all the way into the wing
dowel hole. Clamp the 1A and 1B ribs together. Do not
disturb the wing until the epoxy has fully cured.
D 7 If you are building the Easy Sport 40, edge glue
(procedure described below) two of the 3/32"x 3" x
7-1/4" and the 3/32" x 1-3/4" x 7-1/4" balsa center
sheeting pieces together using thin CA. This assembly is
now the top center sheet. Glue the remaining two 3/32"
x 3" x 7-1/4" balsa sheets together in the same manner.
This assembly is now the bottom center sheet.
If you are building the Easy Sport 60, locate the
five 3/32" x 3" x 24" balsa sheets. From these sheets,
cut ten pieces 10-7/8" long. Cut one of these pieces
2-3/4" wide and another one 5/8" wide. Edge glue
(procedure described below) two of the 3/32" x 3" x
10-7/8" and the 3/32" x 2-3/4" x 10-7/8" balsa sheeting
pieces together using thin CA. This assembly is the top
center sheet. Edge glue the remaining two 3/32"x 3" x
10-7/8" and the 3/32" x 5/8" x 10-7/8" balsa sheeting
pieces together using thin CA. This assembly is the
bottom center sheet.
D 6. Locate the previously laminated 1C ribs. Slide 1C
into position between the aft spar joiner and the TE
brace as shown. You may have to trim 1C to length for it
to properly slide into place. Maintain a 3/32" gap
between the bottom edge of the rib and the work surface
to allow for the center sheeting which will be installed
later. Use a leftover piece of 3/32" balsa to hold the rib
up off the work surface during this step. Hold in this
position and glue in place with thin CA.
