Experiments in using solder paste

Image
Generally when joining metal I use sheet solder, which is economical and in most cases, easy and fast to use. But sometimes it can be a pain to get solder in place around a particularly tiny piece, so I thought I'd have a go with silver solder paste  instead. It's a bit more expensive but it lasts for ages. I'm starting out with a plain silver ring , to which I'm going to solder some silver and copper blobs. Blobby blobby blobby! OK, right. Here we go. Excuse my fingernails, I've been testing out gilding nails with copper leaf. It actually worked pretty well, this is a few days afterwards.. Dot punch to start with. Stops the drill skipping off the surface of the ring. Bzzzzzzzz. Only drill a bit into the surface, don't go all the way through. Repeat until lots of holes. This is fine silver casting grain, usually used for melting down prior to turning into other exciting stuff , but this shape is exactly what I want for this ring. Carefull...

Soldering a Simple Silver Ring

I was asked about doing a tutorial on soldering. So here it is. Soldering is much easier than it looks - with a bit of practice you can be making bezels, joining bits of wire and much more. Main things to remember are clean joins and to heat the piece not the solder. Spending time getting everything nice and clean and properly in place before you get the blowtorch out is important. Notice how much time, even speeded up, I spend aligning the piece of silver in this video. I've heard the word "light-tight" used to check a joint is ready for soldering - if you can see air between the two bits of metal, your joint isn't lined up correctly. Some people say solder won't fill gaps, but it will. That's not an excuse to not having your joints line up though! This ring was only polished to about 800 grit (the  radial polishing discs  you see towards the end are awesome!) so it's still a little satin-y to look at. There's nothing to stop you polishing it al...
