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

atrial-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.

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.

To create a bend in a workpiece:

1.Place the workpiece between the upper and lower rollers, as shown in Figure 17. Turn the thickness adjust knobs to lift the lower roller until the workpiece is held snug between the upper and lower rollers. Be sure to turn the thickness adjust knobs equal amounts.
