>The acid flux did the trick. What he said. Use regular solder with acid flux (aka "tinner's fluid"). Works on stainless steel, too.
A big problem with using silver solder on piano wire is that it requires a torch. The solder may be strong, but the high heat turns the hard piano wire into soft annealed mush. This often defeats the purpose of the strong solder. A soldering iron is cool enough so the piano wire is unaffected. If the solder joint needs strength, there are often tricks to get that. Increase the solder area, or wrap the joint with fine wire before soldering. RCSE-List facilities provided by Model Airplane News.
