I need to pull some doubled up , 0.22mm (9 mil, SWG 34, AWG 32) Cu wire
through small bore sleeving. Some 0.3mm nichrome heater element wire
stretched out until straight, worked rigidly enough, with "peristaltic"
movement as a mouse (does this term translate across the pond ?) . I was
probably lucky that "soldering" the copper to the ni-chrome made a
sufficient strength overlap join to pull 1 wire through but I doubt it
would
work pulling 2 through, soldered or glued, because of added thickness of
overlap bulge, when I have to repeat the process for the double one.
Can anyone think of a source for thin wall ferrule / coupler to solder
or
probably glue over a butt join between mouse and 2 Cu wires, of these
sorts
of dimensions.
Butchered mini-din socket pins are a bit too big diameter, but anything
like
that ?
Would "soaping" the wire help, or are you already doing that?

I tend to use talc for that purpose.

I meant something like this:

Apologies if you already realized this was what I was suggesting.


I suspect that is for high clearance pulls. I've previously found that
constricted pulls should be done dry, eg silicone oil hinders , so I'm
assuming this product would as well. Presumably due to distributed surface
tension of a constricted long run.

I assume that mouse is a recognised term both sides of the Atlantic for the
stidd wire threaders for existing conduit runs.
Is it a myth that it derives from tying a thread to a mouse tail , let it
run through conduit etc, and then pull through cables etc tied to the
thread.?

Cable companies regularly use ferrets to pull a cord through trunking,
I`ve seen it done.
