Installation Instructions for the lever back models 1300 and 1350
The white gold wire springs are permanently attached to the back. Avoid heating the spring as it may loose the spring temper and affect the function. When the lever back is used in our shop, we finish them with a laser. If you choose to rivet instead, be careful not to over tighten the joint as the friction will diminish the free movement of the back.
1000 and 1100 series
These clips come with a removable spring. The clip assembly should be disassembled to attach the stem to your jewelry and then reassembled after it is attached Place a drop of oil on the spring when finished. Heat on the springs may affect the effectiveness of the clip.
The 1000 series clips have a small dimple in the spring to interlock with a small bump on the frame to retain the spring and prevent slipping during operation. Do not file off.
The 1100 series clips have a groove in the spring which interlocks with a crossbar to prevent slipping during clip operation.
At our shop, the pins are finished with a laser, welding them to the tubing. If you don’t have a laser, the pins may be balled with a torch. We do,not recommend riveting as this often results in pinching of the joint and creating excessive friction, diminishing the effectiveness of the clip.
