-15-
creating bends
the Model g5771 can easily 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 your final workpiece until the
desired curve is achieved.
