Wire glue repairing pots etc
Hi all
In case you did not know there is this stuff called wire glue, Its available on ebay It's basically very fine carbon suspended in a solvent One use I've had is in repairing pots On min and submin as used on transistor radios I've had a problem on some radios where the contact between the rivets and either end of the track go high By painting a small dab over the rivet ( it's thin enough to go into the rivet ) it makes a good repair.To finish off you can cover it with superglue to give it some strength Has anyone else found a use for this stuff ? Hope this helps you ! Cheers,Pete Last edited by Goldieoldie; 3rd Feb 2015 at 10:23 pm. Reason: Upload pics |

Re: Wire glue repairing pots etc
I have never seen this stuff I might give it a try. A few years ago I got some liquid conductive paint that repaired spectrum cables. Wire glue probably works similarly.

Re: Wire glue repairing pots etc
It reminds me of the silver conductive paint I bought a number of years ago (perhaps 30). So long that it may have solidified - I have just had a quick look and surprisingly found it inside a couple of minutes - and, although thick, is still liquid!

Re: Wire glue repairing pots etc
You can revive that silver conductive paint by adding some ether to it.
I found that some 'Easy Start' sprays for starting cars are ether, you can spray a little into the pot and the paint becomes thin again. |

Re: Wire glue repairing pots etc
Would this work, and/or be cheaper than silver loaded paint, for repairing flaking metallised coatings on valves?

Re: Wire glue repairing pots etc
Useful to know - thanks Phil.
I've got half a pot of it, too thick for use. |

Re: Wire glue repairing pots etc
Yes thanks for that, I have always relied on Conductive Silver Paint, this sounds like it will be easier to apply to small areas.

If you check on the label of Bradex Easy Start, you will find that it is "naphtha", which is better known as liquid lighter-fuel. Having said that, I bought a can of lighter fluid in "Poundland". Colin (qualified research chemist). |

Re: Wire glue repairing pots etc
You used to be able to get "Ether" at chemists in a pint bottle. I presume it was Ethyl alcohol, as used in hospital's as a disinfectant. Used to work with the stuff, it makes you feel very odd after a time. AFAIK it is also used in model engines .
Wire glue would perhaps be good to stick down frayed tracks in wire wound pots. Andy.

Re: Wire glue repairing pots etc
Back in the 20's , 30's , and 40's the service magazines here advertised a graphite based brush on material to "Repair noisy and defective carbon tracks in pots".
I have not seen it around anywhere here, but if oou can get it there, great. I have talked to old techs that used it and they said it worked quite well. Brake cleaner will dissolve most kinds of plastics or cause them to distort. Works great to clean greasy, groady metal stuff though. |

Re: Wire glue repairing pots etc
Ether (of unspecified type, but presumably not the wave-propagating sort) is available via eBay. Doesn't mean that it's legal, of course!

Re: Wire glue repairing pots etc
I still have a can of graphite spray that was used on T V back covers to reduce line time base interference. Spray a little into the lid and use a cocktail stick to apply. Also useful in repairing buttons on remote controls.
