Somebody better define just what silver solder is! Silver bearing solder is mostly tin with a small addition of silver. It is lots stronger than plain lead solder and requires heat in the range of 400-450 degrees. What is classically known as silver solder is in fact a form of brazing material requiring red heat to make a successful joining of metals. It is highly akin to brazing and much too hot to apply to ribs or barrels. I use the silver solder to braze brass hilts on custom hunting knives I make. Three pieces of brass are invisibly joined by this method and it requires red heat. Better get this straight before somebody screws something up. Chopperlump
