The reason for left and right-hand threaded turnbuckles is that
when one right-hand threaded turnbuckle is opposed at the
opposite end with a left-hand thread turnbuckle, the required
tightening of the flying wires will not result in undue twisting of the
flying wire cables. It is therefore important to understand that each
right-hand turnbuckle needs to have a left-hand turnbuckle at its
opposite end. The simplest way to ensure that this happens is to
use one bag of eight turnbuckles for the top wing panels and the
remaining bag of eight turnbuckles for the bottom wing.
❑
2) Starting with the top two wing panels, select a bag of eight
turnbuckles (either all right-handed or all left-handed) and remove
them from the bag. Adjust each turnbuckle to allow equal in and
out adjustment and use the knurled lock nut to lock this positioning
into each turnbuckle. Uncoil the eight 0.6 x 13-3/4” flying wire
cables. Select eight of the 3 mm x 4 mm copper swage tubes
(16 provided).
Slide one of the copper swage tubes onto one end of one of the
flying wire cables, holding it with your fingers. Insert the end of the
cable through the small, drilled hole at the end of the turnbuckle
and loop it back into and through the copper swage. Bend the end
of the cable, protruding from the swage, upwards to 90
O
leaving
about 1/8” of cable end, as shown.
Pull the looped cable and swage through the turnbuckle hole,
closing the loop to within about 3/32” - 1/8”. Firmly crimp the
copper swage, locking the cable in place. Use a small side-cutter
to clip the 1/8" of cable - bent at 90
O
- leaving about 1/16” or so.
in place, removing all excess liquid and any trapped air bubbles
from beneath the decal. The SIG 4” Epoxy Spreader - #SIGSH678
- is perfect for this job. Remove any excess fluid with a dry paper
towel and allow the decals to set overnight. They will be solidly
adhered to the model without any air bubbles.
The wing walk decal is applied to the top inboard left surface of the
bottom wing. To position this decal correctly, the bottom wing
should be mounted to the fuselage. Also, a full-scale wing walk
has a flat black, textured surface.
Some of you may wish to
substitute the supplied wing walk decal with a piece of #400 wet or
dry type sandpaper. This has about the right texture and look,
making it very believable.
The sandpaper can be cut to the
same dimensions as the decal and adhered in place with a thin
application of Pacer's Zap A-Dapa-A Goo™.
Note that the decal set includes two Hamilton-Standard logos that
appeared on the propellers of many full-size Waco aircraft. As
shown, these logos look really nice on a dummy, non-flying display
propeller. If you want to use these logo decals on a flying propeller,
then we suggest airbrushing them with a light coat of clear epoxy
paint after they have been applied and before using the prop for
flight.
FINAL ASSEMBLY:
In these last assembly steps, the wings will be attached, the
N-struts mounted, the rigging cables installed and the spinner
installed onto the engine and propeller.
❑
1) From the kit contents, locate Bag #22. This bag contains
all of the components used for installing the flying wires. Carefully
note that there are two separate bags containing the turnbuckles
used in this rigging sequence. One of these bags is marked "L" -
for left-hand threads - and the other bag is marked "R" - for right-
hand threads.
