Creating Bends - Grizzly G0971 Owner's Manual

Creating Bends

This slip roll can create constant-radius bends in
sheet metal up to 16 gauge.
Note: The method for creating a specific radius is
a trial-and-error process. Due to the many varia-
tions among metal workpieces, no single position-
ing will create the same curve on all materials. We
recommend using scrap pieces the same dimen-
sions and material as the final workpiece until the
desired curve is achieved.
The main rollers of this
machine present a crush-
ing hazard. Make sure no
body part or clothing is
near the area between the
rollers. Failure to follow this
warning may result in fin-
gers, hair, or clothing being
pulled into the machine,
causing personal injury.
To create a bend in a workpiece:
Place workpiece between upper and lower

rollers, as shown in Figure 28. Turn thick-
ness adjustment knob to raise lower roller
until workpiece is held snug between upper
and lower rollers.

lift rear roller until desired radius bend is
reached (see Figure 30). Make sure to turn
handwheels equal amounts so rear roller is
always parallel with other rollers. Failure to
do so will create a larger radius on one end
than the other, resulting in a cone or spiral
shape.
