Machine Description

The Model T10727 is a 12" slip roll that mounts
in a sturdy bench-mounted vise instead of being
directly fastened to a workbench. This provides
you with the strength and stability you need when
forming sheet metal—without sacrificing precious
workbench space or requiring time-consuming
setups before operating.

The slip roll has three specially positioned metal
rollers to make bends, cones, and cylinders from
sheet metal. The rollers have grooves at one end
that also allow wire to be rolled into various circles
or curves.

The slip roll has a hand crank on one end that
the operator uses to rotate the rollers as they
feed the sheet metal into the slip roll. Two sets of
adjustment knobs allow the operator to adjust the
spacing distance between certain rollers to either
control the radius of ends or accommodate vary­ing thicknesses of sheet metal or wire.

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to avoid
accidental slips, which could cause loss of work­piece control.

HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator to
reduce your risk.

HEARING PROTECTION. Always wear hear­ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!

INTENDED USAGE. Only use machine for its
intended purpose and never make modifications
not approved by Grizzly. Modifying machine or
using it differently than intended may result in
malfunction or mechanical failure that can lead to
serious personal injury or death!

AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.

NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur­ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec­ommended accessories. Using improper acces­sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.

MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.

MAINTAIN POWER CORDS. When disconnect­ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.

Additional Safety for Slip Rolls

OVERLOADING. Overloading this machine can

cause injury from flying parts or property damage.
Do not exceed the machine capacities.

SECURING SLIP ROLL. Before using, secure the
slip roll to a sturdy vise that is securely fastened
to a workbench that can support the weight and
dynamic forces involved in forming sheet metal.
Otherwise, the slip roll may unexpectedly move
or fall, causing serious injury or property damage.

METAL EDGES. Sharp edges on sheet metal can
result in severe cuts. Always wear leather gloves
before handling sheet metal, and chamfer and
debur edges.

TOOLS IN POOR CONDITION. Using the slip
roll with loose or damaged hardware could result
in sudden, uncontrolled movements during use.
Inspect the slip roll for any cracked linkage, con­trols, or loose fasteners. Correct any problems
before use.

GLOVES AND GLASSES. Always wear leather
gloves and approved safety glasses when using
the slip roll.

HEATING METAL. Heating the workpiece with a
torch while it is in the slip roll will weaken the metal
of the rollers and the frame. Do not use a torch or
other similar heating tool near the slip roll.

BACK INJURIES. The cranking motion required
to operate this slip roll is potentially harmful if
proper technique is not used. To avoid back inju­ries, keep your back vertical and never over-exert
yourself or operate the slip roll in awkward posi­tions.

CRUSHING & PINCHING INJURIES. Slip rolls
can quickly crush or pinch fingers or hands. Never
place fingers or hands between or near the rollers
during operation.

Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre­cautions are overlooked or ignored, seri­ous personal injury may occur.

No list of safety guidelines can be com­plete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip­ment, or poor work results.

Cleanup

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.

There are many ways to remove this rust preven
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.

Assembly

Mounting in Vise

Except for the crank handle and the workpiece
support, the Model T10727 has been assembled
and adjusted at the factory.

To complete the assembly:

1. Thread the handle into the crank arm and

tighten with a screwdriver, as shown in
Figure 3.

Crank

The forces exerted on the slip roll during operation
are substantial. The slip roll must be firmly secured
in a vise (see Figure 5 for an example) that is sol­idly attached to a workbench that will support the
weight and dynamic forces of the operation (refer
to Page 18 for options from Grizzly).

Make sure you have a vise secured to a work­bench, then mount the slip roll by tightening the
vise jaws against the lug provided at the bottom
of the slip roll.

Note: Use pieces of cardboard, wood, or padded
jaw faces between the vise jaws and the vise lug
to prevent damage to the slip roll.

Flat Rolling

The Model T10727 Slip Roll can be used to flat
roll sheet metal up to 20 gauge mild steel. This is
done to flatten or slightly reduce the thickness of
workpieces.

When you raise and lower the upper roller with
the thickness adjustment knobs, it is important
to keep the upper and lower rollers parallel by
adjusting the knobs in even amounts. This keeps
the space and pressure even along the length of
the rollers.

Pinching/Crushing

Hazard

To reduce the risk of inju­ry, keep hands, fingers, or
other body parts away from
the rollers during opera­tion.

2. Use the thickness adjustment knobs to adjust

the height of the upper roller so the workpiece
fits between the upper and lower rollers, as
illustrated in Figure 7.

3. Rotate the thickness adjustment knobs clock­wise in even amounts to lower the upper roll­er until the workpiece is held snug between
the rollers.

4. Turn the hand crank counterclockwise to
back the workpiece out of the rollers. Set the
workpiece aside for now.

5. Rotate the thickness adjustment knobs clock­wise five increments on the dials (0.25mm)
to slightly lower the upper roller and increase
roller pressure.

6. Place the front of the workpiece on the
workpiece support. Slowly rotate the hand
crank clockwise to feed the workpiece through
the rollers, as illustrated in Figure 8.

To flat roll a workpiece:

1. Rotate the radius adjustment knob clockwise

to lower the rear roller below the workpiece
path, as illustrated in Figure 7. This will pre­vent the rear roller from bending a curve in
the workpiece as it is fed through the slip roll.

Creating Bends

The Model T10727 Slip Roll can easily create con­stant-radius bends in sheet metal up to 20 gauge.

Note: The method for creating a specific radius is
a trial-and-error process. Due to the many varia­tions among metal workpieces, no single position­ing will create the same curve on all materials.
We recommend that you experiment with scrap
material before using the actual workpiece until
you find the settings that will achieve your desired
curve.

To create a bend in a workpiece:

3. Turn the hand crank clockwise to feed the

workpiece until its leading edge is just above
the rear roller, as illustrated in Figure 10.

4. Rotate the radius adjustment knobs coun­terclockwise 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.

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" diam­eter cylinder. You would use the above formula as
follows:

Figure 11. Setting the bend radius.

5. Rotate the hand crank clockwise to feed the

workpiece completely through the rollers and
produce the bend (see Figure 12).

Workpiece

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 approxi­mately 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).

Once you have the necessary workpiece length,
follow the steps below to create the cylinder.

Note: The method for creating a specific radius
for a cylinder is a trial-and-error process. Due to
the many variations among metal workpieces,
no single positioning will create the same curve
on all materials. We recommend that you experi­ment with scrap material before using the actual
workpiece until you find the settings that will
achieve your desired cylinder.

To create a cylinder:

1. Use the thickness adjustment knobs to adjust

the height of the upper roller so that you can
place the workpiece between the upper and
lower rollers, as illustrated in Figure 14.

CW

Workpiece

In the following step, always err on the
side of making the cylinder too large rather
than too small. It is easy to decrease the
radius of a cylinder later, but very difficult
to increase the radius.

3. Rotate the hand crank clockwise to feed the

workpiece until it is approximately half way
through the rollers.

4. Rotate the radius adjustment knobs coun­terclockwise to raise the rear roller for the
desired cylinder radius, as illustrated in
Figure 15.

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 than the other,
resulting in a cone or spiral shape.

— If the ends of the cylinder do not meet,

equally raise the rear roller at both ends a
small amount, then process the entire cyl­inder through the slip roll again. Repeat as
necessary.

— If the ends of the cylinder overlap, remove

the cylinder from the upper roller (refer
to Removing Workpiece on Page 17 for
detailed instructions). Then, either attempt
to increase the radius by manually bend­ing it and reprocessing it, or scrap the
workpiece and start again.

The Model T10727 Slip Roll has five match­ing grooves on the upper and lower rollers (see
Figure 19) for bending wire, rods, and small tub­ing in diameters of

Figure 19. Roller grooves in five diameters.

To use the grooves:

1. Place your workpiece into the smallest pos-

sible groove on the wheel.

⁄16", 5⁄32", 1⁄8", 1⁄16", and 1⁄32".

A completed workpiece that does not have an
opening wide enough to roll it off the slip roll can
be removed by lifting the upper roller from the
brackets.

To remove cylindrical workpieces:

1. Rotate both thickness adjustment knobs so

that the threads no longer protrude into the
roller bushing space, as shown in Figure 20.

Cleaning the Model T10727 is relatively easy.
Periodically wipe down the rollers to remove dust
and debris—this ensures rust-promoting material
does not remain on the bare metal surfaces.

Treat all unpainted metal surfaces with quality
metal protectants like SLIPIT
(see previous page for offerings from Grizzly).

Lubrication

Lubricating the Model T10727 Slip Roll consists
of periodically (depending upon usage) apply­ing grease to the roller gears and oil to the roller
bushings.

Roller Bushings

Use an oil can to apply a few drops of light
machine oil to the brass bushings at the either
end of the three rollers (see Figure 26). Rotate
the hand crank several times in both directions to
distribute the oil, then wipe away any excess.
