creating bends
the Model t23103 can easily create constant-
radius bends in sheet metal up to 20 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.
2. remove the workpiece from between the
rollers, then raise the bottom roller slightly
by rotating each thickness adjustment knob

rear roller is lowered completely and will not
interfere with the workpiece as it exits the
machine (see

To create a bend in a workpiece:
1. place the workpiece between the top and
bottom rollers, as shown in
figure 17. 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.
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.
