SIMPLICITY COLLET AND SHANK RING | INTERMEDIATE


1: POSITIONING


THE COLLET First, wearing the Optivisor, make sure the collet and head fi t together nicely. If they don’t, you can fi le them slightly so they fi t together.


Position them so the collet is on the soldering board and the shank is being held in position by tweezers suitable for soldering. We recommend wearing the Optivisor with the 2.5 magnifi cation to position the collet and shank, and to solder it. If you don’t need to wear one, please wear safety glasses.


2: APPLY THE


SOLDER Apply gold solder paste where the shank meets the collet and solder on a low heat, always moving the blowtorch around building up the heat slowly. As soon as you see the gold solder fl ow remove the heat and quench in water.


Now you want to reposition the ring so the collet is facing up and the shank is being held by the tweezers. Apply solder paste where the shank meets the collet and solder on a low heat moving the blowtorch around building up the heat slowly. As soon as you see the gold solder fl ow remove the heat and quench in water.


3: CLEAN THE RING We now need to clean the ring in the pickle pot. I use safety pickle, so I make a fresh batch each time I use it.


4: PREPARING FOR


SETTING Next we are going to clean the ring ready for setting the gemstone. Firstly, I used the sander roll inside the ring to even out where the shank was soldered to the collet, then I fi led the areas where I soldered. Secondly, I used a grey Scotchbright pendant wheel all around the collet and shank and lastly I used the extra fi ne Evefl ex burr.
