3.With the help of an assistant, feed the workpiece into the rollers while turning the crank (see Figure 13).

Creating Bends

This slip roll can easily create constant-radius bends in sheet metal up to 22 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 the 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 top and bottom rollers, as shown in Figure 14. Turn the thickness adjustment knobs to raise the bottom roller until the workpiece is held snug between the top and bottom rollers. Be sure to turn the thickness adjustment knobs equal amounts.

4.Continue processing the workpiece by repeat- ing Steps 2 and 3 until the desired results are produced.
