** Dear Jim,

you are one of the most totally ****ed in the head, retarded autistic
pukes alive in the UK - and that is saying something - cos the whole
stinking **** hole is just crawling with them.

People like YOU constitute a serious public menace, for the sole reason
that you are so damn ****ing STUPID.

Not a damn thing you can do about THAT - of course.

But beware, there is plenty OTHERS can do about YOU !!!

The terminally stupid in society cause FAR FAR more trouble than all the
nutters and psychos put together.

Please please please, for the benfit of humanity

get very ill - very soon and ****ing die.

So well can all stop worrying about what

STUPID ****ING CRAP !!!!

you will decide to self publish next.

Nicely put - now tell that to Pucci who can't work out why:

Kitty, I do lots of house wiring and am familiar with how and why cables
are derated according to how they are installed. Thought you used to be a
builder? But of course wouldn't be interested in any actual theory. As
you've said often enough. My local supplier has a technical section which
includes a cable gauge selector for those like you that can't work it out.
But then most builders couldn't be bothered about such stupid things...

Wrong! It's when the guy on the starter button can't see/hear the guy
watching the leads - I'll leave it to you people to fill in the blank
parameter....

Can anyone explain what Kitty is on about? Why would you have a guy
'watching leads'?

The current draw when jump starting an HGV or coach is enough to
vaporise a standard set of jump leads. Even using a set of super heavy
duty it is advisable to have somebody watching them to make sure that
they are not overheating, if the insulation melts and the cables sag
and touch metal then Bang!

Strange, I thought he was a 'microphone monkey'..!!??

(I guess it explains why he's so sour all the time if he has to do
'sparking' to make ends meet!)

You would have though he could have worked it out - without someone watching
the leads for overheating (and feeling them for when they have cooled down
between various attempts) it's all too easy to burn them out especially when
the guy on the starter can't hear anything over the racket of a big diesel
that's not playing ball...

Back 'in the day' true *professional* thick, long, floppy jump leads for
HGVs and heavy plant cost a fortune - I just Googled and it seems it's
impossible to spend much over 200 quid for a pair of 'near miss' 50mm^2
these days...??

(Probably at least what they cost some 30 years ago - and some are as little
as 3 quid or so for a pair...???)

Bingo! (I wish I'd seen your post before I hit 'send' just now!! :-)

Even when the exercise is/was successful and went well it was often a bugger
to get the very hot leads off and out the way without a disaster like
starting a fire or losing part of a finger or thumb....

OK, that's power leads all nicely sorted and we all know where we

let's do speaker cables now....

Take a squint at this:

Nice photo!


Thanks - nowt special, just a fairly satisfying grab in an awkward
situation.

All manual settings as follows, if you are interested:

Shutter - 1/60 sec.
Aperture - f16
Onboard flash - GN13
WB - Flash
ISO - 100
Focus - about 6 inches (Micro-Nikkor)


That's pretty impressive - it'd take me a while (if ever) to get
anything as sharp. With a Canon macro lens (um - EF-S 60mm) this is
about the best I could come up with after about 10 minutes piddling about:

And I learnt the following: ignore the meter and use manual settings,
use the flash, manual focus.

Look, here is how it goes.


(Uh oh, he's off to a bit of a pooey start! :-)


snip what I already know


Provided you end up with a resistance (for the full round trip) under
about half an ohm, that will be fine.


Didn't know that - interesting. Thanks.



Your amp will run into clipping and distortion at a much lower volume
if your speaker leads are too thin (and too long).


Again interesting. I wonder if that's why the new Sony AV amp was shutting
so *readily* the other day - wires too thin??

(Presumably more more powerful than the old one - I've no idea!)




Finally your little test - meaningless, I'm afraid. That odd inch of
single strand added essentially no resistance to the whole cable
because it was so short.


It served my purpose! ;-)

Now for a bit of **OT** (optional, not for those who object):

Wanna see a bag of 'Arse Grit' Swim's keeping round by the compost bins?

Spotted it this afternoon - I wonder WTF she does with it?

The photo looks like an inch of 0.2mm diameter wire from a 79 strand
2.5mm^2 cable. I think it would blow at less than 20 amps but the voice
coil would probably blow first.

0.2mm diameter is rated at 5 amps in open fuse terms.


And the chance of a 5A fuse in the speaker lead blowing under any
conceivable domestic listening situation is as close to zero as makes very
little difference.


Been there, done that with some a 100 wpc amplifier and woofers whose
efficiency was on the order of the legendary AR-3.
