Creating Cylinders - Grizzly G0971 Owner's Manual

This machine poses a cut-
ting hazard if workpieces
are not properly handled. If
necessary, get assistance
to support workpiece. Make
sure all helpers are wearing
leather gloves and safety
glasses when preparing
sheet metal.
Depending on size and shape of workpiece,
you may need assistance to support
workpiece as it exits machine. Failure to
adequately support workpiece may result in
workpiece falling, causing injuries.

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.

Example: Suppose you want to create a 6" diam-
eter cylinder. You would use the above formula as
follows:

C=3.14 x 6"
C=18 ⁄ "

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 32).
