4. Rotate the radius adjustment knobs coun-
terclockwise to raise the rear roller until
the desired radius bend is reached (see
Figure 11).
Note: You must turn the radius adjustment
knobs in equal amounts so the rear roller
is always parallel with the other rollers.
Otherwise, a larger radius will be created on
one end of the workpiece, resulting in a cone
or spiral shape.

5. Rotate the hand crank clockwise to feed the
workpiece completely through the rollers and
produce the bend (see Figure 12).

Creating Cylinders
The Model T10727 Slip Roll can be used to easily
and accurately create cylinders.
To make sure the ends of the completed cylinder
meet correctly, use the formula below to calculate
the required beginning workpiece length.
C = π D
C = Circumference
(Length of Material Needed)
π = Pi (Approximately 3.142)
D = Diameter of Cylinder
Example: Suppose you want to create a 6" diam-
eter cylinder. You would use the above formula as
follows:
C = π D
C = 3.142 x 6"
C = 18.852"
The result of 18.852" indicates that you need to
start with a piece of sheet metal that is approxi-
mately 18.852" in length in order to create a 6"
diameter cylinder.
You can use the slip roll to create a bend with the
correct radius so that the two ends meet, forming
a 6" diameter cylinder (see Figure 13).
