Subject: Re: wire splicing
I essentially posted this mesage before, but the way I posted it didnt
really make clear the distinction between the original message and what i
had replied (just a small portion ! ;), so i wanted to clean it up ...

> 2. Solder is not as good a conductor as copper, there should be minimal
distance between copper strands as possible >(the strands should be
touching). "Tinning" the wires (applying solder before the wires are joined)
means the wires >cannot be twisted around each other and that there is a
relatively thick layer of solder between the two wires (when >joining one
wire to a clip etc is another story). Ideally the wires would conduct
current and hold together without the >solder - the solder's job is to hold
the wires in place and stop impurities getting between the strands.

this seems ultimately very true, but unless you have a poorly done joint,
the added resistence of a well done, but not especially 'tight' joint may be
of very slight impact in this situation ...

ya. seems like the best way is to heat the wire, and then apply the solder
to the heated wire ...

wire).
> 4. (This is hard to describe without a diagram, sorry . . .) make an X
with the wires so that the centre of the stripped wire is at the
intersection of the X (the insulation should be about 1/4" away from the
intersection). Tightly twist the wires around each other so that each free
end is wrapped towards the insulation of the other wire - you should NOT end
up with a T shape, imagine a single wire with 1/2" of the insulation
stripped off the centre of the wire.
> 5. Heat the wire with the iron. Once the wire is HOT, apply the solder to
the wire rather than the iron (really close to the iron) - the copper should
suck up the solder.

the above sounds like a REALLY good method. it also, incidentally, solves
some of the inherent awkwardness of soldering ...
Also, I wanted to add, that people have done, and probably continue to do,
Masters/PhD thesis on how to get good solder joints. But, maybe the ultra
technical points arent so important for a home fix it guy, like most of us
probably are ...
