For disbelievers, I have posted a photo over on alt.binaries.pictures.radio
showing a miniscule section of a 1972 vintage pipe organ relay with
hundreds of
conductors of white DCC conductors.

Hi,

To the best of my knowledge, the last "high-volume" use of DCC wire was
making cables for pipe organs. The pipe organ guys used it because you
could
treat it as pushback wire, and that saved time due to the many thousands
of
connections and conductors a typical pipe organ contains.

Tell me about it. Hundreds of wires cabled together, all the same
color. There oughtta be a law.

Double Cotton-Covered ("D.C.C.") Do they still make this stuff? I would
like to obtain some for winding RF coils for homebrew radio receivers.
Anybody know of a supplier or maybe have some on hand?

I have a 1959 metal spool of #20 AWG wire which is at least single cotton
covered, but I don't think the innermost covering is cotton. Unwinding
the outer green/white threads shows something else underneath, but it
doesn't unwind; it has to be scraped off, but it is NOT enamel. The
spool is 4 inches wide and the wire is about 1.75 inches thick; I have
no idea of the total length, but the total weight is 6+ pounds.

If you think it might serve your purposes, make me an offer. Don't
forget to include shipping (plus something to reimburse me for storing
it for 44 years!-)

You've never worked on ground support test equipment in the
aerospace industry then. 3" diameter bundles of cables that
are all color coded white. 24 AWG teflon covered.
And that was on the "simple" ones.

Or old lead-sheathed telephone cable where they were wrapped
individually in paper...all the same color of course.

"Magnet wire" is not fabric-insulated. Instead, it has a coating of
varnish, formvar, etc. It will work well for winding coils, but it
won't look like DCC.

I believe DCC is actually what was used in the early days for what we
today call "magnet wire." I'm not old enough to be sure of this, but
my impression is that varnished magnet wire replaced SCC, DCC, SSC &
DSC at some point. No doubt this conversion took place over some
period of time.

I would draw a distinction between DCC, etc. and "fabric covered"
wire. I believe the DCC, etc. was just a simple wrap of fibers meant
to take up a minimum amount of space while still allowing close-wound
coil turns to be insulated from each other, while fabric covered wire
was covered with fibers which were actually woven together making it
much more durable. Fabric covered wire was more likely to be used as
hook-up wire, rather than coils.

Others on this list can probably pin this down better.

You're right, Jim, my phrasing was poor. What I was trying to convey is
that if you go to a store or catalog today and ask for "magnet wire",
what you get will be enamaled/varnished/formvared wire - which is easily
available. So if you are looking for cotton-coverd wire, don't ask for
magnet wire.

And a note OT, I set up a new computer a few days ago. In the process,
I managed to send out just TWO newsgroup messages with my real address
in the header before I remembered to munge it. One of them was the
message above. Damn, those spambots are good! My spam intake
immediately jumped about 10X. My SWEN-related quota jumped from 2 a day
to about 50 a day. No choice now but to simply wait for it die out.

But to those who say that the spambots are smart enough to detect and
correct a simple NOPSAM in the address, I say "not so".
