TenTec used to, or maybe still does, use the foam method. But as I
remember
it, they filled the box just halfway, then set the plastic wrapped rigs in
the foam, covered it and the lower foam layer and upper sides of the box
with plastic film, and poured in the top foam layer. Opened like a clam
shell, easy to get out.

I used the original box several times for moving the rig, and I know that
the fellow I finally sold it to used it the same way.
Still have my TenTec boxes up in the garage

I copied the technique several times on a smaller scale for
shipping fragile stuff.
Marty,
PLEASE - How?

Bill,

I used those spray foam cans that they sell for replacing insulation in
refrigerators after repairs and for insulating around electrical outlets
that leak cold air in the winter. It was just a duplication on a much
smaller scale of what I described. I've shipped some ancient Weston meters,
a couple of 4-400's and several fragile optical instruments that way with no
damage reported.

The only problem I had was guessing how much to squirt into the boxes. Had
to do a bit of trimming when it expanded too much. The boxes I used were
considerably smaller than the one the TenTec came in, and I recall needing
only one can for two boxes. I tried to get about 4" of foam all around.
Make sure the plastic bag that you put the items in has no holes or tears;
that stuff really sticks to things.
