• ALWAYS keep the work area free of obstructions.
• Stay alert, watch what you are doing and use common sense when
you are using this equipment. DO NOT operate this tool when you
are tired, ill or under the influence of alcohol, drugs or medication.
• Safety equipment such as gloves and non-skid shoes/boots used for
appropriate conditions will reduce personal injuries.For best footing,
wear rubber soled footwear. Keep floor clear of oil, scrap wood etc.
• DO NOT overreach. Keep your proper footing and balance at all
times.
• Concentrate on the job in hand, no matter how trivial it may seem.
Be aware that accidents can be caused by carelessness due to
familiarity.
• DO NOT wear loose clothing or jewellery which may get caught in
moving parts. Wear protective hair covering to contain long hair.
• Keep equipment clean for the best and safest performance. Check
for misalignment or binding of moving parts, broken parts, or any
condition that may affect the tools operation. If damaged, have the
tool repaired before use.
• ALWAYS hold the workpiece securely. Large work pieces should

WORKBENCH MOUNTING
• The forces exerted on the English Wheel during operation are
substantial. The English Wheel must be firmly secured in a vice (not
supplied) that is firmly secured to a workbench or table that will
support the weight and dynamic pressures of the operation.
• Make sure that you have a workbench and vice setup for the English
Wheel before performing the assembly instructions.
NOTE: Use pieces of cardboard or wood between the vice jaws and
the frame to prevent frame damage.

ASSEMBLY
1. Insert the bracket spacer rod into the
bottom of the lower wheel bracket,
as shown.
2. Turn the frame upside down and
insert the lower wheel bracket into
the frame, as shown.
• Inserting the wheel bracket into
the frame when it is upside down
will keep the spacer rod inside the
bracket.
3. Lay the frame down flat and thread
the lower wheel adjustment screw
into the frame opposite the wheel
bracket.
4. Secure the assembly in a bench
mounted vice (not supplied), as
described on page 5. Screw the
locking knob in the threaded hole, as
shown.
NOTE: Make sure the adjustment
screw handle has enough
clearance from the bench to
fully rotate.

5. Position the upper wheel between
the frame arms. Insert the upper
wheel clevis pin through the arms
and wheel and secure with the
hairpin cotter pin.
NOTE: If the cotter pin does not easily
slide into the clevis pin hole,
insert it as far as you can and
use a small hammer to tap it the rest of the way.
6. Attach the lower wheel storage
1
racks to the frame top with 2 x
1
x 1
/4” hex bolts and 2 x 1/4”-20 hex
/4”-20
nuts.
7. Insert a lower wheel axle rod into
each lower wheel, then place the
assemblies on the wheel storage
rack.

BEFORE STARTING WORK
WARNING: METAL EDGES CAN BE VERY SHARP. AVOID INJURIES BY
WEARING APPROVED SAFETY GLOVES.
Check that all component parts are secure and that the rollers turn freely.
Practice on some scrap metal before attempting work on the actual stock workpiece. Using an English Wheel successfully requires a considerable degree of
acquired skill and experience.
The English Wheel can be used with rollers of various radii in order to suit the task
to be carried out. These various radii allow different curves to be formed in the
workpiece.
SELECTING THE LOWER WHEEL
1. Select the appropriate lower wheel
from the storage rack and place it
on the wheel bracket. When
selecting the wheel, consider the
type and hardness of the metal
being formed as well as the desired
curvature of the metal.
• All the rollers have the same
diameter (50mm) and the same
width (25mm), but the working
surface radii are different. Note that these are always expressed in
imperial units.
• The flat wheel is used for smoothing as against forming curved
profiles.
• Smaller radius wheels produce a tighter curve on the workpiece
than the larger radius wheels. It is also common practice to change
wheels during operation in order to achieve a specific profile.

OPERATION
1. Insert the sheet metal
workpiece between the upper
and lower wheels.
2. Turn the lower wheel
adjustment screw handle to
raise the lower wheel and
gently pinch the workpiece.
• Minor adjustments to the
gap between the wheels
can be made by raising of
lowering the screw handle.
• Pinching it tightly will make it
harder to pass the metal through the wheels and may cause
unwanted creasing.
• Pinching it loosely makes work easier and therefore more accurate.
However, it may take more passes to form the required shape.
3. Before working, turn the locking knob clockwise until tight.
4. Begin forming the metal by pushing and pulling it through the wheels.
NOTE: If wheels form too high a crown in the workpiece, then use a
lower wheel with a larger flat area.
NOTE: If wheels form too low a crown in workpiece, then use a lower
wheel with a smaller flat area.
MAINTENANCE
Always inspect the wheels before use and ensure they are in top condition.
Check that all moving parts move smoothly and freely.
After use, keep the rollers clean and occasionally lubricate moving parts with
a light oil. This will also inhibit any corrosion of the metal components.
For any technical problems contact you CLARKE International Service
Department on 020-8988-7400.
