AA6EG, Pat needs confirmation:
I have been told that if you need to solder to alumium, using ordinary
solder, and rosin flux, that it is possible to take an aluminum object, lay
a small squeeze of motor oil on it, keeping the surface away from oxygen,
and aggressively burnish the aluminum with a scraper, file, or other
scraping tool...through the oil, keeping the newly burnished surface from
developing a micro oxide coating. Then, taking a large soldering iron and
some solder, heating the aluminum through the oil, and simultaneously
applying your solder through the oil (which now, I am guessing is probably
smoking (:-> )to the aluminum surface, and the solder will 'tin' the
alumunum. Once tinned you can then solder to in conventionally.
Can anyone confirm this technique?
Tnx Pat Barthelow aaa6eg@hotmail.com
