[Elecraft] Copper wrapped cotton conductor soldering.

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
