2.
turn the crank clockwise to feed the workpiece
until it is approximately half way through the
rollers.
3.
turn the radius adjust knobs to lift the rear
roller until the desired radius bend is reached
(figure 22). Make sure to turn the knobs
equal amounts so the rear roller is always
parallel with the other rollers. Failure to do so
will create a larger radius on one end than the
other, resulting in a cone shape.
Note: always err on the side of making the
radius too large rather than too small. It is
easy to decrease the radius but very difficult
to increase the radius later.

4.
turn the crank to process the material
through the slip roll. Continue turning until
the workpiece is completely through the top
and bottom rollers (figure 23).
Depending on the size and shape of your
workpiece, you may need assistance to sup-
port the workpiece as it exits the machine.
failure to adequately support the workpiece
may result in the workpiece falling, causing
crushing injuries.

rotate the workpiece 180˚, insert the curved
end into the slip roll, then process the
workpiece through the machine, as shown in
figures 24 and 25.
