Jewelry Piercing
Piercing is the term used when the metal is sawed out leaving an openwork design, or when the background is sawed out leaving the design in the metal.
Transfer the pattern to the metal.
Make depressions with the center punch in the sections which are to be pierced.
Insert the twist drill in the chuck of the hand drill and drill holes marked by the punch. Care must be taken in selecting the drill so the size of the hole will not destroy the traced line of the design.
Set the saw blade in the lower jaw of the saw frame.
Thread the blade through the drilled hole nearest the center of the design.
Support the metal against the lower jaw of the frame while inserting the loose end of the blade in the upper jaw of the frame.
Saw out the section. Follow the directions under sawing.
Return the saw frame to the horizontal position.
Loosen the blade from the upper jaw, and remove from the pierced section.
Insert the end as before through another drilled hole.
Repeat as above until the design or the background has been pierced.
