fixing pewter belt buckle

admin

my uncle gave me his old local 467 plumbers belt buckle as I just passed my interview today, but I will be working at a fitter/Welder. but the part of the buckle that holds in the holes in the belt is broken. I was thinking about trying to braze a little peice of steel on their that file it smooth. Any suggestions?

Reply:Do NOT try to braze pewter.  The name "pewter " covers a large variety of alloys, but all are more than 90% tin which has a melting temperature of about 450 degrees F, much lower than what is normally referred to as brazing rod.  Even hard solders would require temperatures too high for pewter.I also think using an O/A torch on pewter would be a big mistake for a beginner, as it is much too hot and would require expert technique to avoid creating a puddle of pewter on your workbench.I doubt that 60/40 solder would be the best for pewter, but maybe.  Consider talking to a friendly jewellery craftsman or jeweler's supplier to get a recommendation.  The local one I am familiar with is Otto Frei (www.ottofrei.com).  Perhaps there are jeweller's chat groups you could ask.Lacking actual knowledge of working with pewter, I would consider using brazing rod for your replacement part and soldering it as recommended by Hammack_Welding.  I would not recommend steel.Good luck.awright
