MOTM

Aluminum is a royal bear to solder - the issue is that it oxidizes in
moments and the sapphire oxidation is resistant to solder - you need to
either mechanically scrub the two surfaces or use a flux that can dissolve
this ( read: toxic as he%% )

-> Well, this doesn't have anything do to with electronics, but

-> For my fiance and I's (is that bad grammer or what?)
-> wedding, we want to
-> have wedding favors of two interlocked rings.  We got a pile
-> of cheap 10cent
-> rings which are more properly described as
-> nearly-completed-circles.  We've
-> pair them up so that the rings are joined, but now we need
-> to soldier up the
-> gap in the ring to seal them shut.  I'm pretty sure they're
-> silver-coated
-> aluminum, or something like that.  As an expiriement, we
-> tried using the
-> no-wash soldier, but it failed.  I'm not sure if we couldn't
-> get the ring
-> hot enough (it was hot to the touch after applying the
-> iron), or the soldier
-> was the wrong type, or what.
->
-> Does anyone have any advice?  I know I need to get some kind
-> of clamp to
-> hold the durned thing in place, because it kept skidding all
-> over the desk--
-> too light.  Is there a particular type of solder I should
-> use?  Is a cheap
-> radio-shack iron going to cut it (it works A-OK for MOTM stuff!)?
->
-> Thanks!!
