be
sure
the

put
in place.
\Vhen
these blocks
are
not
available,
make
substitutes
of
corrugated
paper,
sponge rubber,
styroioam
or
si;nilar
material.
Customers
quite
often
send a
shock-mounted-chassis
instrument to us
with-
out
the
shipping
blocks
or
a suitable sub-
stitute
in place.
Almost
im·ariahly the in-
strument
will
suifer
some shipping
damage
because
of
the omission.
All
instruments
should he completely
wrapped
in
kraft
paper
or
other
pliable
dust-resistant
material.
Set
the
wrapped
in-
strument
in the original
carton
and place the
dunnage
around
it. Close
carton
and seal
with
gummed
tape.
Tf
the
original
carton
is
not available, use
a
container
of
corrugated
pape1-,
wood,
01·
metal
construction.
The
container should
lie
large
enough to allow a minimum
of
one and
onc-bali
inches clearance
around
the
instru-
ment-top,
sides, bottom and ends. Fill
this
clearance
area
with some type
of
com-
pressible
material,
and
do
not use
<<'uoden
Mocks
lo
support the instnunent rigidly
in
the carton.
Rubberized
hair, wood
excelsior
or
p;qier
excelsior
are
prci
erred
materials.
Float
the
instrument
so as to completely
surround
it
with
an eyen thickness
of
this
protective
material.
In
the absence
of
thcs<;
materials,
sheets
of
corrugated
paper cut
from
other
cartons
will make an acceptable
substitute
filler.
Most
instruments
so packc'd
will
survive
ordinary
shippi1w conditions in
good
shape.
It
takes a Ycry resolute and
satanically-minded
shipping-agent employee
to
succssfully
d<1mage
an
instrument
packed
in
this
manner.
