Once the 10mm round sterling silver stamping shapes arrived I got too and made a band out of 2 mm x 1.5 mm half round wire. I used medium grade solder wire, as I knew that I would have to do more soldering when adding the round shape to the ring. The medium grade solder would hold up better when I reheated the band to attach the shape.
The next step was to add the round shape to the ring. First of all I needed to make a rough flat surface on both the band and the sterling silver round shape. To do this I used a fine file making sure to only roughened up a small area where the two surfaces touch.
When that was all done it was time to solder. Using my soldering block I put the round shape down with the roughened side up and then placed the band on top. Holding the band onto the shape proved to be a problem. I used tweezers but I had trouble keeping the whole thing in place. Once I thought I had them touching I soldered the two together with medium solder wire.
It looked fine , I was really happy that it seemed to have worked. Then I decided to just check the shape was attached. When I pulled on the shape it came apart, it was very disappointing. Well back to the drawing board, as they say.
So I started again. Holding the band I reheated the solder that was still on the join and added some easy solder paste. The solder ran well, but this time I made sure I gave it a little more heat. I then quenched it with water. It was soldered this time but then I discovered that it was not soldered in the right place, it wasn’t centred.
Oh well, I will put this down to experience. In Part 2 I will talk about one solution I came up with.
