Copper wrapped cotton conductor soldering.

Ron ZL1TW
Hi,
     Many moons ago, I was employed as a Telephone Exchange Tech, and one
of the joys :-( of the job was making up switchboard leads for the Toll
boards and old manual exchanges that used to be scattered around the
district. (no new-fangled electronic exchanges in those days)
Anyway......the cords used to come with spade connectors on one end, and we
were the mugs who had to make the tiny loops to terminate the cable in the
jacks, on the other end.
This was done by carefully stripping the covering of each conductor, and
then carefully winding a layer of fine fuse wire over the copper/cotton
conductor, forming a loop, and then soldering over the fuse
wire.......which of course included the copper conductor.
I have used this method to solder copper wrapped cotton mic cords into mic
plugs, but am now acutely aware my fingers aren't as nimble as they used to
be back in the 50's.
Might be a handy hint for "rolling your own" mic cord?
Cheers......Ron ZL1TW
