Machine Description

A slip roll is a machine used to flatten and create
constant-radius curves in sheet metal workpieces.
The three roller system adjusts to allow the opera­tor to complete a number of procedures.

The T25688 can quickly adjust to create cone,
spiral or continuous cylindrical shapes with sheet
metal up to 22 gauge. Workpieces can be bent
to job specification, straightened, or even slightly
flattened. In addition to sheet metal, this slip roll

1

⁄8", 3⁄16", and 1⁄4" grooves for precise wire/rod

has
bending.

The T25688 features a quick-release upper roller
designed specifically for the easy release of cylin­drical workpieces from the machine.

Safety Instructions for Machinery

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.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.

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!

USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica­tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to 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 Site Considerations

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.

Before cleaning, gather the following:

Bench Mounting

Another option is a "Direct Mount" (see example
below) where the machine is secured directly to
the workbench with lag screws and washers.

The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.

The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.

Before every use, follow these procedures to set
up the slip roll for safe, accurate, and efficient use.

To prepare the slip roll for use:

1. Turn the thickness adjustment knob to lower

1

the bottom roller to approximately

/4" below
the top roller. Use calipers or a spacer to set
the distance between the rollers evenly at
each end (see Figure 10).

Rear Roller

CCW

CCW

Figure 10. Slip roll preparation.

2. Lower the rear roller until it is approximately

even with the bottom roller (see Figure 10).
Use calipers or a spacer to set the rear roller
even with the bottom roller at each end.

This slip roll can be used to flat roll sheet metal up
to 22 gauge. This can be done to straighten and
slightly flatten workpieces.

The main rollers of this
machine present a pinch­ing hazard. Make sure no
body part or clothing is
near the area between the
rollers. Failure to follow this
warning may result in fin­gers, hair, or clothing being
pulled into the machine,
causing personal injury.

To flat roll a workpiece:

1. Place the workpiece between the top and

bottom rollers, as shown in Figure 11. Turn
the thickness adjustment knobs to lift the
bottom roller until the workpiece is held snug
between the top and bottom rollers. Be sure
to turn the thickness adjustment knobs equal
amounts.

3. With the help of an assistant, feed the

workpiece into the rollers while turning the
crank (see Figure 13).

Creating Bends

This slip roll can easily create constant-radius
bends in sheet metal up to 22 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 using scrap pieces the same dimen­sions and material as the final workpiece until the
desired curve is achieved.

The main rollers of this
machine present a pinch­ing hazard. Make sure no
body part or clothing is
near the area between the
rollers. Failure to follow this
warning may result in fin­gers, hair, or clothing being
pulled into the machine,
causing personal injury.

Figure 13. Flat rolling the workpiece.

4. Continue processing the workpiece by repeat-

ing Steps 2 and 3 until the desired results are
produced.

To create a bend in a workpiece:

1. Place the workpiece between the top and

bottom rollers, as shown in Figure 14. Turn
the thickness adjustment knobs to raise the
bottom roller until the workpiece is held snug
between the top and bottom rollers. Be sure
to turn the thickness adjustment knobs equal
amounts.

until its edge is directly above the rear roller,
as shown in Figure 15.

This machine poses a cut­ting hazard if workpieces
are not properly handled
when exiting the rollers. If
necessary, get assistance
to support the workpiece.
Make sure all helpers are
wearing safety glasses
and leather gloves when
assisting in the use of this
machine.

Figure 15. Feeding the workpiece.

3. Turn the radius adjustment knobs to lift the

rear roller until the desired radius bend is
reached (see Figure 16). Make sure to turn
the knobs equal amounts so the rear roller is
always parallel with the other rollers. Failure
to do so will create a larger radius on one end
than the other, resulting in a cone or spiral
shape.

CW

Depending on the size and shape of the
workpiece, you may need assistance to sup­port the workpiece as it exits the machine.
Failure to adequately support the workpiece
may result in the workpiece falling, causing
injuries.

4. Turn the crank to process the material

through the slip roll. Continue turning until
the workpiece is completely through the top
and bottom rollers (see Figure 17).

Creating Cylinders

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

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=Circumference
(Length of Material Needed)

π=Pi (Approximately 3.142)

D=Diameter

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

C=πD
C=(3.142) x 6"
C=18.852"

C=πD

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 using scrap pieces the same dimen­sions and material as the final workpiece until the
desired curve is achieved.

To create a cylinder:

1. Place the workpiece between the top and

bottom rollers, as shown in Figure 19. Turn
the thickness adjustment knobs to lift the
bottom roller until the workpiece is held snug
between the top and bottom rollers. Be sure
to turn the thickness adjustment knobs equal
amounts.

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 18).

2. Turn the crank clockwise to feed the workpiece
until it is approximately half way through the
rollers.

3. Turn the radius adjustment knobs to lift the
rear roller until the desired radius bend is
reached (see Figure 20). Make sure to turn
the knobs equal amounts so the rear roller is
always parallel with the other rollers. Failure
to do so will create a larger radius on one end
than the other, resulting in a cone shape.

Note: Always err on the side of making the

radius too large rather than too small. It is
easy to decrease the radius but very difficult
to increase the radius later.

5. Rotate the workpiece 180˚, insert the curved
end into the slip roll, then process the
workpiece through the machine, as shown in

Figures 22–23.

Figure 22. Re-inserting the workpiece.

Figure 20. Setting the radius.

4. Turn the crank to process the material

through the slip roll. Continue turning until
the workpiece is completely through the top
and bottom rollers (see Figure 21).

6. Continue to process the workpiece until the
cylinder is formed, as shown in Figure 24.

Bending Wire

—If the ends of the cylinder do not meet, lift

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

—If the ends of the cylinder overlap, remove

the cylinder as described in Removing
Workpiece on Page 18. Then, either
attempt to increase the radius by manually
bending it, or scrap the workpiece. Lower
the rear roller equally at both ends then
process a new workpiece through the slip
roll. Repeat this step as necessary.

This slip roll can be used to shape wires, rods,
and small-diameter tubing. The wire grooves can
also be used when rolling sheet metal that has a
wire bead at one end.

To use the wire grooves:

1. Place the workpiece into the smallest pos-

sible groove on the wheel. The three sizes

1

⁄8", 3⁄16", and 1⁄4"(see Figure 25).

are

Example: Suppose you want to bend a piece

1

⁄8" rod. Though it would fit in any of the

of
three grooves, you would use the

1

⁄8" groove
since it is the smallest possible groove that
the rod will fit into.

SECTION 5 : MAINTENANCE

LubricationSchedule

For optimum performance from the machine, fol­low this maintenance schedule and refer to any
specific instructions given in this section.

Daily Check:

• Loose mounting bolts.

• Any other unsafe condition.

Weekly Maintenance:

• Clean machine.

• Lubricate gears.

• Lubricate roller bushings.

Cleaning

Cleaning the Model T25688 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.

Roller Gears

Lift the gear guard cover and apply a dab of
white lithium grease to the upper roller gears (see
Figure 32). Rotate the hand crank several times
in both directions to distribute the grease to both
gears, then wipe away any excess and close the
cover.

, or Boeshield® T-9

Roller Bushings

Use an oil can to apply a few drops of light
machine oil to the brass bushings at either end of
the three rollers (see Figure 33). Rotate the hand
crank several times in both directions to distribute
the oil, then wipe away any excess.
