A defunct DVD player meant we needed to re-arrange the snake's wedding behind the Idiot's Lantern and one Scart lead became redundant.

Parsimony prevented me from ditching it, so I opened it up to find a useful looking collection of fine cables, some in neat pairs.  At 4ft-6" long the 21 different cores will doubtless come in handy, already 2" of the fine black are earmarked for repairing a Graham Farish chassis.

Forgive me if this is an exercise in instructing your mother's mother the art of avian ovoid vacuum content extraction, but having seen these things for sale in Pound shops the idea could save a plank builder enough for a glass or two of SLW.

Doug



Best wishes,

Doug

Hi Doug,

Good source if you don't worry about colors or wire gauge. I browse my local second-hand electronics store for various bits of table taken from obsolete electronic equipment.

I think this is intended for thicker cable, although it would manage the first stage for many multicore cables.

He has enough support to go ahead and it is a British contribution.

I think you meant "bits of cable" there, Nigel:mrgreen:
I love the term "Snakes' wedding", and this is a lovely idea. No sense letting wire go to waste.

Seems to be my day for digging up old threads :shock:

I've bought some GoW platform lights and without wanting to make too large a hole in the platforms, was looking for some fine flexible cable for connecting them up.

I'd seen mention of Scart leads somewhere else on the web and knowing we had a few sparks on here I thought I'd do a search, since I have four lying around.

My question is, anyone any idea what voltage/current these wires would take without melting quest:

Looking around it looks like their intended use is something like 1 - 4 volts and a couple of mA.

I'm intending to run the lamps at about 9v, so I wouldn't expect the current to actually reach 70 milliamps.

I recently decided that no one would ever want an old centronics printer switch I had lying around so I opened it up to see what was inside. A whole load of short wires ideal for all those small jobs. Network cable and telephone cables are also good sources for wire as well.

Ihave used telephone wire for my layouts from day one except the bus wire which is household stuff, 50 vlt and 10amp for the cable
never had any probs with it,
:thumbs;-):cool:

Thanks David and Owen, I came across a long never used telephone extension wire when digging out the Scart leads yesterday, so another source of wire.

Why on earth did I throw all those long cat5 leads in the bin :thud


Having dismantled the Scart the wires look remarkably like 10/0.1 equipment wire, so fine for my use :thumbs

One thing to watch out for with some CAT 5 leads - make sure they are not CCA - copper coated aluminium. If connections are soldered, they tend to break very easily. Also the tensile strength is poor. They usually have 'CCA' stamped along the outer sheath.

Hi Doug.    Scart cable, 
Your topic from a while back?? On recycling the wire for model railway use , has inspired a question on the voltage that can be carried( not curried?) by the wires, plugs and sockets?  I had been getting around to using a spare scart cable for a model railway project , but, I required a socket, then I saw that Maplin had a couple and I went out and purchased one.
Now I am thinking ( I do that sometimes) if you have it earmarked for a Graham Farish chassis, then it should be okay for the LED’s on my layout? Just eight of them. Please advise. Kevin

Well, Kevin, it survived running in a GF chassis for 1/2 hr in each direction on a fairly heavy white metal OO9 loco, so the micro amps that LEDS take should be fine. For peace of mind, when I rigged up a lighting circuit for a card and paper  mill ages ago, I left it switched on resting on an old ironing board 'asbestos' square for 24 hours in my workshop (equipped with smoke alarms) and wished I hadn't bothered. My trickle charger for my ride-on mower was warmer!

Hi Doug   Thank you very much for your reply. But, what happened to the chassis after that 1/2hr in each direction ??Best wishes. Kevin

Hi Doug.  This is another reply, one thing I did notice, not all the wires were the same gauge? So does that mean only the thicker wires are suitable for some model railway projects?    Kevin

IIRC I used virtually the thinnest wire, not a lot of wriggle room in a OO9 chassis! I did find that the little tags on the ends wouldn't take solder...?

Hi Doug.  Thank you for your reply. I hope that you are managing with the snow down there. I will soldier/ solder on, and do my best with my plank.   Best wishes.   Kevin
