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
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.

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.
2. Remove the workpiece from between the
rollers, then raise the bottom roller slightly
by rotating each thickness adjustment knob
approximately
1
⁄4 turn. Also, make sure the
rear roller is lowered completely and will not
interfere with the workpiece as it exits the
machine (see Figure 12).

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

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