Creating Cylinders - Grizzly T32718 Owner's Manual

Creating Cylinders

This slip roll can be used to easily and accurately
create cylinders.
If you know the diameter of the cylinder you want
to create, use the formula below to calculate the
length of material needed.
C=πD
C=Circumference
(Length of Material Needed)
π=Pi (Approximately 3.14)
D=Diameter
Example: Suppose you want to create a 6" diam-
eter cylinder. You would use the above formula as
follows:
π
C= D
C=3.14 x 6"
C=18 ⁄ "

The result of 18 ⁄ " indicates that a piece of sheet

metal that is approximately 18
needed 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 20).

Workpiece
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.
To create a cylinder:
1.
Turn thickness adjustment knobs to adjust
lower roller to approximately
roller (see Figure 21).
2.
Lower rear roller to lowest position (see
Figure 21).

3. Place workpiece between upper and lower
rollers, as shown in Figure 22. Turn thick-
ness adjustment knobs to raise lower roller
until workpiece is held snugly between upper
and lower rollers. Make sure to turn knobs
equal amounts so lower roller is parallel with
upper roller.
