Double Cotton-Covered Wire - where to obtain?
 
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?


thanks,

Dave

Both belden and Alpha made it, so I would start with Newark, Allied, or
another large OEM distributor. Also, see if there is a motor rewinding
shop in your area that might use it on small motors. You might pick up a
partial spool at a decent price.

I don't think that Belden or Alpha has made that kind of wire for at
least 2 decades. Got both of their big factory catalogs here and
all I find is "magnet wire" in either light or heavy (two coat) plastic
insulation. My new Mouser catalog has only part of two pages
with "magnet wire," both being the equivalent to old "enamel
covered coil wire." Might try the search engine at Digi-Key, but I
doubt there will be any success.

Last I was at a place that rewound electric motors was 8 years
ago and they had only heavy plastic covered "magnet wire."

The old cotton-coverd coil wire was okay 4 to 5 decades ago but
doesn't offer much for coil building except for the cotton insulation
being excellent to absorb shellac that will dry and hold everything
together very nicely. Actually, back in the old days, a ceresin wax
application was more likely to be applied...dried quicker and moved
the product through production faster. I happen to like McCloskey
"Gym-Seal" floor varnish to coat home-wound inductors, solenoidal
to toroidal...it's all petroleum-based, not a polyurethane, and doesn't
come loose in high moisture environments like some polyurethanes.
"Gym-Seal" seems to stick to polyester and polyamide magnet
wire coatings very well.

There's a slight difference in distributed capacity between DCC and
enameled wire, DCC usually being slightly less (any coating applied
over it will change that to not less). Not enough distributed capacity
to worry about in my estimation.

There's a slight difference in inductance for a given coil form dimension
between DCC and enamel-covered, the DCC having slightly less for
the same number of turns. Again, not enough to worry about.

The last cotton covered wire I used was around 1970. I bought a large
spool surplus to make a bunch of heavy duty degaussing coils for early
color TV sets. 300 turns of 17 AWG DCC, double enameled wire that was
surplused by Picker X-ray, and sold to Mendelson's, in Dayton Ohio. They
had hundreds of partial spools, and I think they still had some in 1987,
(The last time I was at their store in Dayton, Ohio) It was still listed
in the last belden and Alpha catalogs I received, but I would have to
dig them out to get the dates.

Back in the 1950s I helped restore a pipe organ

guy removing it just wanted to scrap the pipes for
their metal, but died shortly after he started the

All the cable bundles had been cut with an axe!!

It took a whole summer to buzz out *thousands*

Dave -

Contrary to what has been posted, cotton cloth braiding machines still
exist --
even at the big wire manufacturers -- however today they are usually used
for special orders.

Now, Odis W. LeVrier OWNS a cloth braider and makes beautiful replacement
cloth wire for
antique telephones (cloth covered tinsel, cloth covered line cords, desk set
cords) Photos are on
his web page. Please contact Odis directly for your special requests or
orders - he may be able to accommodate!
http://www.houseoftelephones.com/index.htm

Other "urban legend" - No one is fixing classic WE, AE, SC telephones
anymore - WRONG
Steve Hilsz just fixed my Dad's old Northern Electric desk phone - now worth
over $ 200
in collectable/antique telephone market ! You should see what the original
candlesticks sell for !!

As far as I can see, these web sites are offering cloth-covered stranded
wire, such as would be used for hook-ups under chassis and such. I'm
looking for "D.C.C." wire such as was used for winding coils. I guess it
would be considered "magnet wire" ?

"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.

BFoelsch November 1st 03 01:24 PM

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. The last
manufacturer was, I believe, the Philadelphia Insulated Wire Company.

This stuff was getting very hard to find around 1980, I have no real reason
to suspect that it is made at all any more. But, I am sure that there is a
lot of it laying around. I just don't have any!

Just curious. I got some spools from a friend, but don't really know
when it is an advantage to use the cotton covered wire instead of the
normal enamelled copper wire. Used it for some VLF purposes to make
lower self capacitance of coils, but appying single strand wire was
just to use what was available instead of multistranded wire

How sure are you of this? I don't recall seeing it in the Belden
catalog, and when I built a Tesla coil in the 50s a Belden engineer
helped me (Belden is still located in the town where I grew up, a
GREAT field trip, BTW.) The instructions we were following called for
DCC magnet wire, but we couldn't buy any even then. The Belden
engineer even inquired to see if their prototype shop could whip up a
batch just for us, but they didn't have any way to do it by then.

I suspect that it's been 50 years since anyone in the US has made SCC,
DCC, SSC, or DSC wire.

Everyone remember those?

How sure are you of this? I don't recall seeing it in the Belden
catalog, and when I built a Tesla coil in the 50s a Belden engineer
helped me (Belden is still located in the town where I grew up, a
GREAT field trip, BTW.) The instructions we were following called for
DCC magnet wire, but we couldn't buy any even then. The Belden
engineer even inquired to see if their prototype shop could whip up a
batch just for us, but they didn't have any way to do it by then.

I suspect that it's been 50 years since anyone in the US has made SCC,
DCC, SSC, or DSC wire.

Everyone remember those?

As I mentioned in another post, I was using good quantities of it (on a
"serious hobby" basis), in 22 - 26 awg until the late 1970's. Curiously,
until that time you could also buy DCC cable, 20 - 26 awg, conductors were
bundled in groups of 11 and the whole assembly was enclosed in PVC and
impregnated with paraffin; this cable again being a specialty item for the
pipe organ market.

I also remember silk covered wire, somewhere around here I have a small roll
of #40 silk covered. I always loved those cute little wooden rolls that old
magnet wire came on, kind of like a giant roll of thread. I am trying to
remember some of the manufacturers, maybe I'll look around and see if I
still have an old spool laying around with a label on it.

Both belden and Alpha made it

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.

Belden (ha ha), Birnbach, Cornish Wire Co. on mine.

I definitely don't want to go into the supply business, but if
anyone absolutely *has* to have silk wire, I have spools of 31, 33,
34, 35 and 40 DSC, 38 double nylon, and 10x38 and 10x41 silk litz.

Cheers, Alan

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.
