The small shield shaped cabochon was made last year and surfaced in my bench this weekend. I decided to make a fold formed base to hold the cab. First step is to trace around the cab with a sharpie onto the background metal.
I love the balance of the six pointed star and so chose this as my form to fold. Using a straight edge to trace parallel lines on either side of the center is the first step. Even though I started symmetrical you will see how it is easy to get somewhat different results during the bending.
I folded this first bend over the edge of my bench block and then folded it flat and confirmed the fold by hammering along the fold. This work hardens the line so it will show up on the face of the piece later.
You can see how the very edge was hammered tight and in order to make the next fold a flat metal chisel is forced into the fold to help open it up.
The second parallel fold is hammered then the piece is annealed with a torch to soften the metal to make unfolding possible.
The two folds are lined up fine and it is time to bend the other four folds,two at a time. I put the square edge into my vise up to the line and pound over the metal and beat along the seam to harden or confirm the line fold.
This is the result after annealing and before fully flattening the metal. One more time it is to be folded diagonally this time and the same process to confirm, anneal and unfold.
Here the cab is positioned to show the piece still fits. within the design.
I then cut out the star shape leaving the folds as the edge. I used the jewelers saw for this.
Because i wanted to continue the riveted theme from the center piece onto the star, I traced the points of the star to cut out contrasting metals that matched the cab.
The triangle pieces were riveted to the metal one at a time after cutting them from the sheet with shears.
This shows the pieces in place. I used E-6000 glue to hold the points in place for punching the holes and riveting.
I wanted to attach the cab to the center with a dog ear finding. So it was traced onto copper sheet and cut out.
The jewelers saw makes quick work of cutting out the shape.
Here the cup is riveted into place. The piece was then polished,sanded and buffed to give texture and surface detail. And the cab was placed in the center and the tabs folded over to hold it.
