The fit must be a tight mechanical fit to begin with. The holes and the surrounding area must be free of lube, dirt, oxidation, or anything else that would jeopardize the bonding action of the glue . Super glue holds metal to metal very well. Resoldering the joint is a pretty good idea if your any good with a small torch. Once again, clean the area really well. The joint may have failed in the first place because of contamination of some kind. Heat the loop ends, and clean with steel wool. Mike the wire used to make the loop in an unsoldered area and choose the same sized drill bit to clean the holes in the sos rail. Put an ample dab of flux on the loop ends and re-insert in the rail. Resolder using some good quality solder. Rosin core solder would probably work, as would acid core, but I've had fairly good results with just plain old solder. Allow the solder to cool by itself and re-install the rail in the piano. A number of techs indicated the use of a small butane torch. It sounds ideal for this purpose. I've always used a standard sized propane torch, lately with Mapp gas, and have never needed anything else. But then, I solder coax connectors in the field without burning my pinkies, when I do remote location ham radio stuff. Good luck Larry Fisher, Metro Portland, Or.
