HI THERE
Just a thought , I have often made my own alum boxes , for projects
that I have built myself , and have always wanted to solder
the edges shut , for a more pleasing look ,
or sometimes solder two pieces together.

,Never mind the old resin trick etc ..
I wanted to proper solder them , with an iron ..yer

I have used different irons , and temperatures
various fluxes , and methods
and nothing has ever been successful

I know all about oxidiodsation , so I thought
could I solder it in a vacuum ??? or oxygen free
environment ??


say I get myself a large plastic box , air-tight joints
and Perspex top , with an air-tight fitting door
and a pair of fitted gloves , and a one way air valve
connected to the hoover , to withdraw some of the air
out of the box ???? , maybe even light a candle in the box
to burn up the last bit of the oxygen ??

the box would be large-enough for me to have all the tools
I need , small scrapers , iron , solder , flux , and the box iam soldering ,
etc

any thoughts ????

I would be prepared to go to this much trouble
if the idea would work . iam sure I can get air tight joints
by using rubber gaskets and expandable foam and glue
between the joints etc ...

I don't really want to hear about the construction method
down-falls in your replies , more about the theory of
soldering aluminium in a vacuum situation or lack of oxygen environment


sorry to be blunt , but as so often happens in news articles
the main question or topic is often lost by the 3 or 4th reply
then it goes of a tangent to the main question .


anyway hope some one may be able to help ,
or has had experience of actually doing what iam trying to do

cheers for now
