• For best results and maximum
forming power, insert metal only
halfway into the Jaws
(Fig 10)
.
• The “bunching” or “pocket-
ing” that typically occurs
when shrinking can be quickly
hammered out or smoothed by
inserting the metal deeper into
the jaws.
• Maximum control is achieved
with the pressure exerted on
the handle and number of
strokes used while forming the
metal. Move the metal back and
forth along its length until the
desired radius is obtained.

Never operate the Shrinker or Stretcher Jaws without a piece of metal
between them as the hardened gripping teeth of the jaws will be
permanently damaged.
The Shrinker and the Stretcher Jaws are “toothed” to allow them to grip and
“push” inward toward the center together to shrink metal or “pull” outward
toward the sides to stretch the metal. These teeth will leave slight indenta-
tions which, depending on the hardness of the metal, can be removed with an
abrasive cloth or wheel.
At this point, the basic operating instructions have been described and practice using the Shrinker
Stretcher on scrap material is highly recommended. As with many metal working tools, a period of
“trial and error” is needed to achieve a degree of proficiency in their use. Remember, a little time and
material wasted at this step will avoid disappointing results on an actual project.
