RE: [TCML] DUMB QUESTION OF THE DAY



if you really must solder instead of using an interference fit as several of us have recommended, you need to look up what kind of solder is effective on tungsten - I do know that for tungsten-carbide tooling, you need to use about 50% silver, along with some other metals to solder (well, "braze", I suppose) - but in your situation, soldering really makes no sense at all.  as I noted yesterday, drill a hole the same size as the wire (not larger!!!) and press te wire in - if you want, you can heat the dime to make it expand and ease the "press it in" part - a set of wire size drills from 60 down is cheap, as is a holder you can twirl in your hand (I presume you don't have a sensitive drill press (that's a type of tool, not an adjective) available - if you do, use the sensitive drill press.> Date: Thu, 3 Jul 2008 07:32:32 -0700> From: evp@xxxxxxxxxxx> To: tesla@xxxxxxxxxx> Subject: Re: [TCML] DUMB QUESTION OF THE DAY> CC: > > Ed,> If flux is a problem, make your own!

I have several different types here including the "killed acid" you mention. None of it does a thing on the tungsten.> > Ed> > > _______________________________________________> Tesla mailing list> Tesla@xxxxxxxxxxxxxx> http://www.pupman.com/mailman/listinfo/tesla_______________________________________________
