68. P
repare places to mount four(4) small L-brackets
o
n the upper surface of the top wing by boring two(2) 1/16-inch holes approx. 3/16 inch
apart and 3/16 inch deep in each of the upper wing’s
four(4) preinstalled “hardwood islands” [38:45].
69. Apply CA adhesive to harden the holes you bored in the
wood where the small
L-brackets are to be
mounted.
70. Drive two(2) 6 mm
(1/4-inch) wood screws
through each small
L-bracket and into the
two(2) holes you bored
into each of the
four(4) preinstalled
“hardwood islands”
in the upper surface of
the top wing [39:26].
71. Attach a clevis with a brass pull-rod to each of the four(4) small
L-brackets. Using crimp-tubes, attach a 63-inch long top-wing
wire to each of these four brass pull-rods and clevises: a) Slide a
crimp-tube onto the end of the cable; b) Pass the end of the cable
through the hole in the brass pull-rod’s unthreaded end; c) Bring the
end of the cable back into and all the way through the crimp-tube;
d) Loop the end of the cable back into the crimp-tube and leave the end
of the cable inside the crimp-tube; e) Using long-nosed pliers, firmly
squeeze several places along the length of the crimp-tube to crimp the tube
securely onto the cable.
72. Locate the two(2) small predrilled holes just inboard of the outer ribs of the upper
wing’s wingtips. Run a sharp pin through the top and bottom openings of each pre-
drilled hole to open the covering material at each end of each hole.
73. Guide each top-wing wire from its small L-bracket, clevis & brass pull-rod attachment point: a) Through the hole
nearest the fuselage in the top of the nearest wing-cable tube; b) through hole nearest the fuselage in the top of the
remaining wing-cable tube; c) into the nearest predrilled hole near the outer wing rib, through the wing, and out the
hole in the bottom of the wing; d) and toward the bottom of the nearest outside strut [39:41].
74. Pull toward the loose end of each cable to draw the four(4) top-wing wires tight. Secure each top-wing wire to a
brass pull-rod and clevis and to the bottom of the nearest outside strut using the same attachment process as in #71,
except: As you loop the end of the cable back inside the crimp-tube for the last time (i.e., 71-d), allow the excess
cable to extend out of the crimp-tube; then, after you have crimped the tube securely onto the cable, snip off the
excess cable with a pair of diagonal or side-cutter pliers and discard the excess cable [42:10 & 42:16].
75. Secure both ends of each top-wing wire by permanently anchoring each brass pull-rod into its clevis with a few
drops of CA adhesive.
