I’m having some frustration soldering a ring onto a hunk of metal - I just can’t get the solder to flow into the holes I’ve drilled into the main body.
low carat gold (~9 carat) and easy silver solder, borax as flux
Jump ring is three twisted strands of wire, total diameter is 1.5 mm. Holes (2) are slightly larger than this.
setting everything up dry, wetting the joint with flux and flowing the solder into the hole - no luck - beads on the surface or runs UP the wire (not down into the hole
filling the holes with solder and when it’s melted pushing the wire in. one hole had an air pocket, which didn’t help, but in any case, the metal clearly wasn’t wetting properly.
I’ve made about 7 attempts at this now and running out of ideas… any suggestions appreciated.
