Mark,
How would you support the transformer with wood?
Remove it? Wood inside the case? Above or below
tranformer?
Tnx

As people have stated, it's a combination of both.
People cared more about
their work back then and probably took better care
in how they handled
stuff. There was less pressure to just get the
stuff outta here than now
I'm sure.
Secondly it does not matter whether so much whether
you use a particular
material or not, it's HOW the materials are put
together that matter.
Someone in a reply said it doesn't matter how it's
packed if it gets dropped
six feet. I think you are stating my second point
from a different angle. I
wouldn't send a Valiant out my door unless I felt
confident... yes,
confident that it could withstand a six foot drop.
Probably an eight foot
drop. That's not unusual and std packing procedure
for a business. It's not
hard to do but it takes a little work and more than
that it takes thought on
how it should be boxed. I've sent hundreds of items
around the world.
Fragile glass items. Heavy radios. I never had one
damaged in transit. ALl
of those packages were expected to withstand at
least a six foot drop.
As an example, here is what I would do with a
small-medium sized
transmitter:
1. Remove the tubes. They get individually wrapped
in bubble-wrap and
shipped separately. Any other loose pieces get sent
separately in another
box. If you want you can in some case wrap that
stuff up and put it inside
but if you want to be sure, pack it separate.
2. Depending on the tranmitter, it's value, etc I
might need to make a
wooden support for the transformers.
3. Wrap this up in both directions with bubble wrap.
The one with the bigger
bubbles, not the small-bubble kind. Tape it good.
There should be at least a
couple of inches of bubblewrap on every surface.
4. Using bubblewrap or high-density foam fit this
assembly into a box. Not a
bad idea to put it into a heavy garbage bag and tape
before it goes in the
box.
5. Tape this box up. Tape it up GOOD. If heavy use
strapping tape as I
describe below. Now this is where many people would
stop. It looks like it's
ready to go, right? Well many people would ship this
out but it's not ready.
6. Get ANOTHER, larger box. ALlow for 3-4 inches in
every direction. In
between the two boxes you need some cushion. I
pesonally like peanuts but if
you use them they must be packed DENSELY. You want
the inner box to be able
to move a bit, but not much. Pack the peanuts in
there tight. Tape this box
up tight. Then get your strapping tape and wrap two
double bands of that in
each direction, each band about 25% of the way in
from the edge of the box.
If the box is long then I'd add two more bands in
that direction. The
strapping tape will prevent the box from bursting
should it be dropped on a
corner for instance. It's very strong stuff.
You're done.
Now if the transmitter is really large, or extra
heavy (say 80 or 100lbs)
then you need to go to the next level and crate it.
Basically you follow the
steps above and then put that assembly into a box
that is made of plywood
with reinforced corners, etc. Making a suitable
crate is somewhat of an
art... a story for another day.
If you follow those steps listed above you will be
able to drop that
transmitter 6-8 feet without any damage to the box
or the transmitter. It
will hit with a funny dull sounds and sort of bounce
(which is what you
want, thats' the energy being absorbed and deflected
not transferred to the
transmitter).

Could someone explain to me how radios were
shipped back in the
50's so that
they arrived at the dealers with no apparent
damage. I wonder what the
original packing was back then?
