View Full Version : Need some advice in coil hand winding

Sorry if this is not Altec/Lansing related but maybe someone could give me an advice:

I have some Jensen V21 treble drivers (for a Leslie Horn) which had a shorted voice coil winding. I wound off the wire. It is 0.11 mm (something like .00393 in). 43 turns on a 2" coil. Measures to 14,2 Ohms DC resistance.

Anyway, provided I can get the exact diameter wire somewhere (any sources in US, Europe? - I'm from Germany and I'm already investigating sources here but american gauge is difficult to obtain here), I would like to know if there is some liquid or glue one could use to seal the wire when winding the two layers of windings.

I have to do one layer forth and the second traveling back upon the first layer and solder it to the flat wire connections.

I thought of using epoxy glue but doubt that it has the heat restistivity.

Any help welcome.

Moin Krischu,

from Pollin.de or Reichelt.de you can get "Kupferlackdraht" with 0,1 mm diameter The calculated resistance would be 15,6 Ohms - not bad at all.

What about "Sekundenkleber"? It can be applied very thin. Make a test coil on a bog roll (Klorolle), many turns achieve quite a force. Apply an increasing current. Look what will burn up first, the glue or the isolation.
Maybe the experts here have a better idea.

Good luck with your undertaking!

Sekundenkleber = Lacquer ? may break up with high volume vibration......
