Remove the cap from the mandrel and carefully squeeze between the jaws of the nylon jaw pliers, to close the gap between the spiral and the coils.
Note: - Be very gentle, if you squeeze too hard you will squash the cap out of shape.
Trim the tail (approx ¼") from the bottom of the cap. Grasp the tip of the wire with the chain nose pliers, holding the jaws at a 90° angle to the end of the wire
Carefully bend the wire 90° towards the inside of the cap, so that the end is hidden inside.
Note: - This can take a little practice, to get the pressure on the wire just right, so that it bends in the right place, without disturbing the shape of the cap.
Grasp the cap between the thumb and forefinger of your less dominant hand, holding all the coils in place, while you shape the end with the other hand.
Now the cap is shaped, grasp with the nylon jaw pliers once again, in the same way as before, to give one final squeeze, closing all gaps, it also helps to harden the wire in position.
