Metalworking Techniques -
Piercing

Most of us are amazed when we first see the
uniformity of the small cut out portions of a piece of German silver such as
the one pictured above. The design of many brooches and other German silver
items worn for every day wear, woman costumes or worn to peyote meetings is
often created by a simple method called “piercing.” Rather than cut each
area out with a chisel or jewelers saw each piece is individually punched
out. Such a technique was introduced by many of the trade silver items and
German silver items acquired and manufactured by the eastern and
southeastern tribes. When these tribes such as the Delaware, Senecas,
Shawnees, Caddo, Choctaws and Seminoles brought these light (thin gauge)
pierced brooches, earrings and turban bands they became a design source for
the Indian smiths of the Southern Plains, and such design techniques are
used to present.

TECHNIQUE The technique is as
follows. Grind down the end of a 4-5 inch piece of tool steel, drill rod,
old file, etc. to one of the shapes shown below. |
|
Make
the ground 1/2 - 3/4 inch surface as perpendicular as possible to the stamp
face, (Fig.l). The larger the face the more difficult the stamp is to work
with. Practice with a small round or diamond shape first. |
|
Next, melt some lead (1 or 2 lb. fishing sinker) into an old pot with a
propane torch and let it cool. Later, dump out the hardened lead.
Most brooch work is done in 22 gauge silver or
lighter. Pierce the metal as follows:
- Place metal on lead block-good side up.
- Hold stamp firmly in place, hit 2 - 3
times with hammer, punch will pass through metal and a piece of metal the
exact size of the punch face will be left in the lead.
- Pull metal off the end of the stamp.
- Hit front side of metal with rawhide or
plastic hammer.
- Turn metal over and pound back of
pierced portion with a small ball peen hammer until the metal is flat. Now
go to the next position to be pierced.
This technique, though simple, takes
practice. The stamp often wants to “jump” out of its original position after
the first hit and other such problems occur. Inner edges of the pierced
portion need not be filed. Do your piercing before the regular stamping then
finish the surface. The end of a piece of hardwood may be used in place of
the lead. When surface of lead is covered with dents filled with pierced
pieces, melt and use again.

business. We're not sure about the Smoke Signals article. Be aware that since
it's original publication, lead is now classified as a more hazaradous material.
We suggest you use the alternate hardwood method. If you choose to use lead, be
sure you fully understand safe handling procedures before you start.)
