Radius Bending
Radius bending is most commonly used to make
cylinders and cones, both of which are formed by
making a series of small, closely-spaced bends in
the workpiece.
For cylinders, the bends are evenly spaced and
parallel to the workpiece edges while cones have
a series of uneven bends that are not parallel to
the edges (see Figure 15).
Even Bends

Use this information as well as the steps listed in
Typical Bending Operation beginning on Page
5 to radius bend.
If you cannot get your bends close enough
together for your operation, remove the fasteners
shown in Figure 16 to remove the bending leaf
from the breaker bar. Removing the bending leaf
will decrease the overall bending capacity but will
also allow for very tight tolerances.

Pan & Box Bending
When bending a piece of flat metal into a box,
you will need to make multiple bends on the same
workpiece. While you will use the same procedure
as described in Typical Bending Operation on
Page 5, you will also need to consider the clear-
ance needed to clamp and bend the remaining
sides of the workpiece without interfering with
your first bend (see Figure 17).

Use the following steps to bend a four-sided pan
or box and provide the necessary clearance for
subsequent bends.
Note: The Model T32714 is only capable of bend-
ing pans/boxes that have 90 degree angles.
Eye injury hazard! Always
wear safety glasses when
using this machine.
Do not operate unless machine has been
securely clamped or mounted to workbench.
Failure to secure machine before use could
result in crushing injuries.
Only bend stock that falls within bending
capacity of this machine. Bending stock
thicker than 20 gauge will damage machine.
