Hello Chuck

Are you using a heavy-duty soldering iron and continuously
"scrubbing-like-hell" the Aluminum surface under the oil with the 'tip' to
break-thru the AL-oxidation layer to allow the solder to whet the Al? I
continuously feed the solder into the region to build-up a solderable
'blob' which can easily be soldered to later.

Subject: Topband: Soldering aluminum coax shield to copper wire

Content-Type: text/plain; charset="iso-8859-1"

Many many years ago I had partial success soldering aluminum coax shield to
copper wire using the motor oil technique. I also believe I had some flux
(unknown type) that helped.
But I had no luck with motor oil last week and can not find the flux I had,
which might be a good thing as it is 20 years old.

So what is the easy reliable cheap method to get the job done?
