nicole Posted September 21, 2013 Share Posted September 21, 2013 Hi Folks, I am making some copper bowls that have brass legs that I attach from the bottom. I tried gently brazing woth an oxyacetylene torch but it is really tricky and on leg two I managed to melt my bowl. Should I be trying silver solder and a cooler flame? Something else? Thanks a bunch for any suggestions Nicole Quote Link to comment Share on other sites More sharing options...
ianinsa Posted September 21, 2013 Share Posted September 21, 2013 "lead" solder? Though the "bulk" of solder sold these days contains no lead! use plumbers flux. Ian Quote Link to comment Share on other sites More sharing options...
Chinobi Posted September 21, 2013 Share Posted September 21, 2013 Maybe tenon and rivet? That might be easier if the legs are big(relatively) and the bowl is thin, prevent differential heating. Quote Link to comment Share on other sites More sharing options...
Dave Budd Posted September 21, 2013 Share Posted September 21, 2013 i made some copper and brass cups recently that had brass or copper legs attached, I went the route of riveting with copper rivets. If I wanted to join them without pins then I would use silver solder on account of its greater strength than soft plumbers solder. If you have three seperate legs, then you may need to get three types of silver solder (each has a different melting point so you can do multiple solder joints on an item) Quote Link to comment Share on other sites More sharing options...
tzonoqua Posted September 21, 2013 Share Posted September 21, 2013 What dave said, silver solder. Depending on how big the bowl is, you either have to do them all at once, somehow cleverly bound in place using some binding wire but not bound too tight to the bowl that the wire will bend the bowl when it gets hot, or three stages of solder. Or rivet. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted September 21, 2013 Share Posted September 21, 2013 I use Oxy /acc and a small pit, but I also have a jewlery torch set. Quote Link to comment Share on other sites More sharing options...
