11.3 Forming a Radius 1. Adjust the pinch roll as needed. 2. Turn on the slip roller and insert the workpiece from the front. Make sure the stationary roll is rotating counter-clockwise. 3. When the material reaches the point where the radius is to begin (Figure 6a), stop the machine and raise the idler roll an equal amount on each end to achieve the desired bend. 4. Re-start the rolls and continue until the bend is completed (Figure 6b). Support the workpiece as it exits the machine. 5. If a smaller radius is needed, adjust the roll distance and re-feed the workpiece. Figure 8 11.5 Bending Wire There are three wire grooves at the end of the pinch roll and idler roll, to accommodate a 5/16", 3/8" and 1/2" wire. See Figure 9. Use the smallest groove into which the wire will comfortably fit. Bend the wire using the same principles as described for forming a radius. To make a complete loop of wire, use the instructions for forming a tube. Figure 6 11.4 Forming a Tube A tube can often be made with a single pass through the machine, as follows: 1. Adjust the pinch roller as needed to accommodate workpiece thickness. 2. Feed the workpiece into the machine. As it nears the end (Figure 7a), stop the machine and reverse direction (Figure 7b). Figure 7 3. To remove the tube from the stationary roll, pull the sleeve outward until it clears the end bracket; then pivot the roll outward, as shown in Figure 8. 4. After the tube is removed, reposition the stationary roll, making sure the sleeve is pushed back in completely, as shown in Figure 8. Figure 9 12.0 Maintenance 1. Keep the rolls clean and rust-free, and periodically apply a light film of oil. 2. Place a few drops of 30W oil into the holes at each end of the rolls (see Figure 9). Then operate the machine for a few seconds to distribute the oil. 3. Apply a light coat of oil to the exposed end of the stationary roll beneath the sleeve (shown in Figure 8). 4. Keep the gears lubricated with a good quality, non-hardening grease. (Remove end cover to access gears and chain.) Operate the machine to disperse the grease. 5. Apply a light coat of grease to the pinch roll and idler roll adjustment screws (see Figure 1). 10

11.3
Forming a Radius
1.
Adjust the pinch roll as needed.
2. Turn on the slip roller and insert the
workpiece from the front. Make sure the
stationary roll is rotating counter-clockwise.
3.
When the material reaches the point where
the radius is to begin (Figure 6a), stop the
machine and raise the idler roll an equal
amount on each end to achieve the desired
bend.
4.
Re-start the rolls and continue until the bend
is completed (Figure 6b). Support the
workpiece as it exits the machine.
5.
If a smaller radius is needed, adjust the roll
distance and re-feed the workpiece.

Forming a Tube
A tube can often be made with a single pass
through the machine, as follows:
1. Adjust the pinch roller as needed to
accommodate workpiece thickness.
2.
Feed the workpiece into the machine. As it
nears the end (Figure 7a), stop the machine
and reverse direction (Figure 7b).
Figure 7
3.
To remove the tube from the stationary roll,
pull the sleeve outward until it clears the end
bracket; then pivot the roll outward, as
shown in Figure 8.
4. After the tube is removed, reposition the
stationary roll, making sure the sleeve is
pushed back in completely, as shown in
Figure 8.

Bending Wire
There are three wire grooves at the end of the
pinch roll and idler roll, to accommodate a 5/16”,
3/8” and 1/2” wire. See Figure 9.
Use the smallest groove into which the wire will
comfortably fit. Bend the wire using the same
principles as described for forming a radius. To
make a complete loop of wire, use the
instructions for forming a tube.

Maintenance
1. Keep the rolls clean and rust-free, and
periodically apply a light film of oil.
2.
Place a few drops of 30W oil into the holes
at each end of the rolls (see Figure 9). Then
operate the machine for a few seconds to
distribute the oil.
3.
Apply a light coat of oil to the exposed end
of the stationary roll beneath the sleeve
(shown in Figure 8).
4. Keep the gears lubricated with a good
quality, non-hardening grease. (Remove end
cover to access gears and chain.) Operate
the machine to disperse the grease.
5.
Apply a light coat of grease to the pinch roll
and idler roll adjustment screws (see Figure
1).
