As promised, here are my photos from the Fabrication 3 class I took at Revere in July. The two projects were a sweat-soldered layered brooch, and a hollow box ring.
The brooch was a fun project, as we used a rolling mill to impress the silver with patterns from fabric, paper, and plastic textures. I patterned the base of my brooch with a glittery tulle fabric, and paper-punched snowflakes. The top layer was rolled with 220-grit sandpaper. I domed the two layers, then soldered them together (which was harder than I bargained for, LOL), and soldered on the back pin hinge and catch.
The hollow box ring was quite challenging. It starts as two long strips, the inner ring and outer wall. The inner strip is soldered together into a ring; the outer strip is soldered to the outside of the inner ring. In the end, the bottom half of the ring is solid metal, and the top is hollow. Once attached, these are soldered onto a flat sheet, forming the first side of the hollow ring, which is then cut out from the sheet and cut out on the inside (remaking the finger hole, basically.) Once this is done, you repeat the process with the other side, forming a box ring with an open top.
There’s a lot of filing and finishing to be done at this point, to make all the corners square and flush. A pattern is chosen for the top, and the final bit of soldering is done (there must be a hole either in the top piece, or drilled through the bottom part of the hollow ring, else the ring will explode during the final solder. No, really.) I got as far as soldering the top on, and then finished the final trimming, filing and polishing closer to home.
