I’ve got a soldering problem that I had to give up on, for fear of
damaging the piece. So I’m turning to you for suggestions.
I was presented with a spectacular cast sterling cuff in the form of
a dragonfly to repair. It’s a big piece, think more Gothic dragon
than delicate fly. Probably 50g of sterling, at least. The
dragonfly’s antennae extend outward from the center and touch the
sides; they are just 18 or 20ga wire attached at two points each. One
of the anteannae is broken, not surprisingly.
a) degreased the whole bracelet with Dawn and water,
b) cleaned up the break,
c) filed it flush,
e) and tried to pick solder it with my Little Torch #4 tip and easy
solder (David Fell). And my #5 tip, twice. And gave up. The silver
"chars" the minute I touch it with the torch, and the solder ball
never flows. I think the whole bracelet is sucking all the heat, but
I can’t figure out how to isolate the wire so that I get it hot
enough to flow. Or is it something else?
I recommended that the customer take it to a jeweler with a laser
Any ideas, or am I simply trying to do something that will not work?
