<< it's that the thread crests can overheat and be in danger of burning if exposed to the direct heat of the flame. >> I definetely agree with what Harry says and filling with a steel threaded plug works. Something not mentioned is: DON'T PLUG THEM ALL! Gotta have some place for the air to escape! When silver soldering it is very necessary to concetrate heat to your largest piece and only at the last minute to play the torch to the soldered area. I think this is the hardest part, as that takes patience. Bob Starr <A HREF="http://www.geocities.com/cgnr.geo/">ART IN GARDEN RAILROADING-THE CGNR </A> http://www.geocities.com/cgnr.geo/
