WORKBENCH MOUNTINGb

• 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 set up 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 racks to the frame top with 2 x/4”-20x 111/4”-20 hex nuts.1/4” hex bolts and 2 x
   

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 the 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 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.
