Wire glue repairing pots etc

[Goldieoldie]

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

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.

Regards, Robin.

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!

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.

Would this work, and/or be cheaper than silver loaded paint, for repairing flaking metallised coatings on valves?

Useful to know - thanks Phil.
I've got half a pot of it, too thick for use.

Yes thanks for that, I have always relied on Conductive Silver Paint, this sounds like it will be easier to apply to small areas.

I wouldn't have thought so, presuming you are referring to diethyl ether. It was used as a general anaesthetic for some time and there are a good few cinematic scenarios of someone rendering another person unconscious by applying an ether-soaked cloth over their nose and mouth . Diethyl ether is also very, very inflammable. The term "ether" is applied to a class of chemical compounds, of which "diethyl ether" is just one. The other "ether" which I assume we are all familiar with is that which is supposed to propagate radio waves.
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".

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.

The problem with ethyl alcohol (ethanol) is that if it is drinkable without serious health risks, then duty is payable on it . That's why methylated spirit was used - the dye made it look bad, the methanol made it poisonous and the pyridine made it taste and smell bad. There was also "industrial methylated spirit", or IMS, which was clear and lacked the dye or pyridine, but still not a good idea to drink it, as it was denatured with methanol. That might be what you remember in pint bottles from the chemist. As far as I can recall from my days of making and flying diesel (not glow-plug) engine model aircraft, the fuel seemed to be largely diethyl ether, but with oil added to keep the engines lubricated. The diethyl ether vapour would ignite on compression with air. We were also rather naughty in putting this fuel behind lead slugs in our air-guns as kids; a bit more pokey!

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.

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

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.
