Here is a photo of the instructor (Jerald Day) and his setup.
I selected a red jasper stone which resembled a ring and the color of the outfit I wore. I began by chosing the type of band which would wrap around the stone. You can see the stone and the band below. I began by cutting the band just large enough to go around the stone. I then created a 1/8 inch lap joint and soldered the band closed.
After successfully soldered I had to place the band on a mandral and use a brass hammer to pound out the joint. After soldering and pounding the joint was unnoticable.
You may have realized, I cut the band to match the size of the stone. I then lap joined the band closed. Wouldn't the band be too small? Yup. I had to continue pounding the joint until the space was regained. At this point the band was shaped to the stone again and a flat piece of silver was chosen as the backing.
I had to solder the shaped band to the back. I did this by placing 7 smal 1/8 inch pieces of silver solder around the endg of the band. I used a solution of borax and water as a flux. The solder is drawn to the heat, so heading the center of the back drew the solder underneath.
To cool and clean the piece, it was dropped into a mild acid and then rinsed with water.
Here is the "cleaned" piece succesfully soldered.
I was hoping the pendant would match a ring I had purchased. I selected a thin twisted silver wire to accent the edge. Again the piece had to be cut, shaped and soldered on. This took some doing. I placed the solder on top of the twist brade. As it turns out, the solder should be on the bottom as the piece is heated from below and the solder runs faster that way. This portion took about 20 minutes to work out as I was a slow learner and had to do it four times. Ick!
Should be done with the edge now. Another acid bath and rinse.
I selected some 1/2 round double wire for the loop portion. I wanted the loop to match the style of the ring. I cut the wire and shaped it as desired. The pieces were rested on a fire brick and soldered together.
Now all the joinery was done, the instructor tested all my soldering and it held. Time to clean up the mess.
Here is the instructor holding a handful of stainless steel shot which is placed inside a rock tumbler. After about 30~40 minutes of tumbling, all the dirties were gone!
