ReEAs
hae
in
the
subpanel
into
the
shaft
coupling
to
the
variable
capacitor
shaft.
Tighten
both
set
screws
in
the
coupler.
Assemble
the
flexible
shaft
coupling.
This
assembly
is
comprised
of
two
black
plastic
that
have
flat
round
faces
that
are
1"
in
diameter
and
have
two
round
pins
3/32"
in
diameter
projecting
1/4"
from
the
face.
These
two
pieces
assemble
face
to
face
with
the
pins
of
one
through
the
two
holes
in
the
other.
Orient
these
pieces
so
that
the
set
screw
holes
of
both
are
in
line
with
each
other.
This
assembly
will
be
completed
by
using
a
hot
soldering
iron
pressed
down
on
each
of
the
pins
that
project
through
the
face
plates.
The
plastic
material
will
soften
and
spread
out
to
form
heads
on
the
pins
that
will
pre-
vent
the
two
pieces
from
separating.
CAUTION:
In
order
to
provide
the
flex-
ibility
necessary
in
this
coupling
there
must
remain
some
space
between
the
two
faces.
Cut
a
strip
of
stiff
paper
or
cardboard
approximately
3/8"
wide
x
1-1/2"
long
and
insert
between
the
faces
to
act
as
a
temporary
shim
while
the
plastic
pins
are
being
heat
formed.
After
the
four
pins
have
been
"headed"
(Do
not
burn
them
into
the
face
plates.
The
two
plates
should
be
able
to
move
slightly
on
the
pins.)
Remove
the
shim
and
note
the
restricted
movement
of
the
two
halves
on
the
pins.
Install
a
6-32
x
5/16"
set
screw
in
each
half.
Insert
the
short
5/8"
piece
of
double
flatted
1/4"
phenolic
shaft
into
one
end
of
the
flexible
coupling
approximately
1/4"
or
until
the
inserted
end
is
flush
with
the
inside
face.
Tighten
this
set
screw.
Now
insert
the
other
end
of
this
short
shaft
into
the
straight
coupling
on
the
variable
inductor
shaft.
Align
so
that
one
of
the
flat
surfaces
of
this
shaft
is
under
the
set
screw
and
tighten
the
screw.
The
other
setscrew
which
engages
the
inductor
shaft
should
not
be
tightened
at
this
time.
Examine
the
3-1/4"
long
1/4"
diameter
aluminum
shaft.
This
is
the
variable
inductor
extension
shaft.
Note
that
there
is
a
small
hole
located
1-5/16"
from
one
end.
Insert
in
this
hole
the
small
round
pin
(.039"
diameter
x
1/4"
long).
Press
this
pin
into
the
hole
until
it
bottoms
being
careful
to
not
bend
the
pin.
Insert
the
flatted
end
of
this
shaft
from
the
front
of
the
subpanel
through
the
panel
bushing
and
insert
into
the:
flexible
coupler
on
the
inductor
shaft.
The
flat
will
engage
the
flatted
hole
in
the
coupler.
Tighten
the
set
screw
in
the
flexible
coupler.
The
front
end
of
this
shaft
and
the
pin
are
extending
to
the
front
of
the
subpanel.
The
dial
pointer
system
consists
of
a
pointer/carrier
assembly,
dial
string
and
elastic
cord.
The
carrier
and
pointer
assembly
have
been
pre-assembled
for
your
convenience.
The
slot
in
the
carrier
engages
the
top
edge
of
the
subpanel
with
the
red
pointer
extending
down
over
the
calibrations
on
the
panel.
Check
to
be
sure
that
the
carrier
can
freely
slide
along
the
top
edge
of
the
subpanel.
If
there
is
a
tendency
to
bind,
now
is
the
time
to
correct.
If
the
channel
in
the
carrier
is
not
wide
enough
it
can
be
widened
by
carefully
sanding
the
in-
side
of
the
channel
with
sandpaper.
Be
careful
not
to
fracture
the
plastic.
If
a
bind
is
due
to
an
irregularity
in
the
panel,
it
should
be
corrected
at
this
time
To
attach
the
elastic
cord,
tie
a
knot
around
the
small
plastic
stud
in
the
car-
rier
located
to
the
right
of
the
pointer.
Use
a
little
elastic
as
necessary
and
position
so
that
the
rest
of
the
elastic
cord
leaves
the
stud
from
the
right
side
of
the
stud.
Draw
this
knot
tightly
and
secure
the
loose
end
piece
to
the
remaining
cord
by
tying
the
two
cords
together
tightly
with
a
short
length
of
the
dial
string
positioning
this
knot
as
close
to
the
stud
as
possible.
This
should
prevent
the
knot
from
becoming
untied.
Now
with
the
elastic
and
pointer
assembly
removed
and
placed
on
your
working
surface,
measure
the
relaxed elastic
to
a
point
15-1/2"
from
the
stud.
Double
the
remaining
length
back
on
itself
from
this
point
and
tie
a
knot
with
both
sections
so
that
the
flattened
loop
measures
about
5/8"
from
the
bend
to
the
knot.
Place
the
pointer
on
the
top
edge
of.the
subpanel
and
route
the
free
length
of
elastic
over
the
top
of
the
upper
right
pulley
on
the
subpanel.
Continue
the
elastic
down
the
right
edge
of
the
subpanel
and
around
the
lower
brass
spacer
stud
in
the
lower
right
cor-
ner.
Continue
the
elastic
across
the
subpanel
and
slip
the
loop
end
over
the
threaded
bushing
of
the
"SWR
set"
pot
in
the
lower
left
area
of
the
panel.
Now
slide
the
pointer
assembly
across
the
subpanel
to
make
sure
that
the
elastic
has
sufficient
stretch
to
allow
the
pointer
to
reach
the
"0"
calibration
mark
on
the
scale.
:
Now
prepare
the
dial
string
by
doubling
one
end
and
tying
a
knot
with
both
