hifi - feeding wires

[User]

 

[Crackle]

How about using the old wires to pull through a new thinner stronger feed wire first and then use that to pull the new cable through, less chance of it all snapping and parting.

Apparently trained ferrets are used sometimes - I kid you not

Remember many years ago help a friend - lifted floorboards at opposite ends of lounge, put cat down one end (with piece of string tied to cat's tail!) while he encouraged it to go to his end! Pulled string through with cable attached to string

That may be the only real use a cat has ever been put to

temporary solder/join with tape or something new cable to end of old cable and just pull through

Depends on how good you are at knots

Plaster coving, or polystyrene?

If it's polystyrene, and there's any resistance to pulling wires through, and the wires go round any corners, I can see a real danger that rather than pulling a new wire through, the wire may just burst out through the coving. I'd suggest gentleness and caution.

You can get electricians' tools for pulling wires through cavities quite cheaply these days - semi-flexible rods and hooks and things. It might be wise to research these before you begin....

the fishing rods are great , but going round tight corners they just wont go. you will end up repairing the coving where you have to open it up to get around the corner. My advice would be to draw out the old ones and pull in a polypropylene string on the ends .

strip the 2 cores about 3 inches and then fold back while twisting to form a loop. tie the poly prop twine into the loop and put ONEwrap of insulting (sic) tape. then gently pull through. a good assistant who can pull it under tension will be invaluable.

thats about the only way to do it without risking a huge amount of repair works.

need pics of how to do the loop ?

I used to run catv network cables and this is exactly what I would do. The existing cables might not move if they were cemented in. If in doubt rip out the existing coving and replace it, putting up coving is very easy.

Cut out the corners of the coving, if polystyrene, and replace after feeding in new wiring. That is still possible with plaster coving.

If you are able to pull the old wiring through then make sure that someone is pushing the new wiring through at the same time as the old is carefully pulled. The pushing is often the more important part of it as the pulling is more of a guide to keep it moving and on track around corners.

It may even be useful to have someone supporting the tension on the corners of the cove while the wiring is in transit.
