Great Planes Float Kit 60 - GPMQ1874 - Manual (Page 6)

If you are building the 20 or 40 Sports Floats, skip to
“Construction of 20, 40, 60 Floats” in the next column
on this page.
❏
1. On a flat surface covered with wax paper, laminate the
die-cut 1/8" plywood forward and aft spine to one 1/16" die-
cut plywood spine doubler with 6-minute epoxy. Use weights
to hold the pieces together. Hint: Before the epoxy fully
cures, use a #11 blade to remove excess epoxy that gets into
the notches or oozes out from between the laminated pieces.
With Great Planes 6-minute Pro
™ Epoxy, this can be done
about 10 to 15 minutes after the epoxy has been mixed.
❏
2. Glue the other doubler to the other side of the
assembly with 6-minute epoxy.
❏
1. Since the par ts are smaller, both forward keel
doublers may be laminated to the forward keel at the same
time. Mix up some 6-minute epoxy and apply to one side of
both die-cut 1/16" plywood forward keel doublers. Then
position a doubler on each side of the die-cut 1/8" plywood
forward keel. Hold the pieces together with weights.
Remove the excess epoxy before it fully cures.
❏
1. Trial fit the die-cut 3/32" balsa upper float side,
lower float side and aft float side. Make adjustments if
necessary. When satisfied with the fit, use thin CA to glue
the three pieces together over a building table covered with
waxed paper. After the CA has cured, use 150-grit
sandpaper and a sanding block to sand both sides of the
float side flat and smooth. Make another float side,
identical to the first.
❏
2. Use thin CA to glue the die-cut balsa forward deck to
the aft deck. After the CA has cured, sand both sides of
the deck flat and smooth.
NOTE: If your float parts do not match each photo exactly,
it is because these instructions are written for all three
sizes. Regardless of which size Spor t Float you are
building, the forward end of the float deck is the end
that tapers slightly.
❏
1. Drill 1/8" holes through the punch marks in the die-cut
1/8" plywood forward and aft strut mounting plates.
❏
2. With the die-cut 1/8" plywood former doubler F
centered on the die-cut 1/8" plywood former E, align the
bottom edge of the doubler F with the lightening holes in
former E. Glue the pieces together with thin CA.
