the Model g5770 can easily create constant-
radius bends in sheet metal up to 22 gauge.
radius bends in sheet metal up to 22 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 your final workpiece until the
desired curve is achieved.

to create a bend in a workpiece:
1. place the workpiece between the top and
bottom rollers, as shown in
figure 16. turn
the thickness adjust knobs to raise the bot-
tom roller until the workpiece is held snug
between the top and bottom rollers. Be sure
to turn the thickness adjust knobs equal
amounts.

Steps 2 and 3, flipping the workpiece each
time until the desired results are produced.
Note: Since the rear roller on the Model
G5770 does not lower completely out of the
path of the workpiece, a slight bend may
be created. Flipping the workpiece between
passes minimizes the bending effect.

the main rollers of this
machine present a pinch-
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.
