RE: [TCML] DUMB QUESTION OF THE DAY

[William Noble <william_b_noble@xxxxxxx>]

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_______________________________________________
