A WARNING!
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
•
Lead from lead-based paints.
•
Crystalline silica from bricks, cement and other masonry products.
•
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip
ment, such as those dust masks that are specially designed to filter
out microscopic particles.
Symptom

is marred or
scratched.
Workpiece does
not move through
wheels without
excessive force.
Workpiece curve is
too high.
Workpiece curve is
not high enough.
Workpiece curve will
not form.
Workpiece has
wrinkles.
Possible Cause
Possible Solution
1. Too much wheel pressure. 1. Reduce wheel pressure.
2. Wheels are diy. 2. Clean and protect all wheel surfaces (see Page 16).
1. Too much wheel pressure. 1. Reduce wheel pressure.
2 Wheel bearings at fault. 2. Replace wheel bearings.
1. Lower wheel radius is too great.
1. Use a lower wheel with less radius (crown).
1. Lower wheel radius is not enough. 1. Start with lower wheel of least radius and work up to
correct radius for the operation.
1. Not enough wheel pressure. 1. Gradually increase wheel pressure.
2. Lower wheel has flat suace. 2. Use lower wheel(s) with a radius (crown).
1. Tracking pattern at fault. 1. Use a consistent and smooth tracking pattern that
overlaps with each back-and-foh pass.
2. Too much wheel pressure. 2. Start with least amount of pressure, then gradually
increase pressure when the curve stops forming.

&WARNING
Damage to your eyes, hands and feet could
result from using this tool without proper
protective gear. Always wear safety glasses,
leather gloves, and steel toe footwear when
operating this tool.
NOTICE
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj
ects. Regardless of the content in this sec
tion, Stark Tools will not be held liable
for accidents caused by lack of training.
Tracking Tips
•
Stretching metal into a curve should be a
gradual process.a lwaysstart withjustenough
wheel pressure to prevent the workpiece from
skipping or slipping through the wheel fter
the initial curve has formed, increase the
pressure slightly and continue stretching the
metal. r epeat this process until the desired
curve is attained. using too much pressure
will damage the workpiece surface and pro
duce poor results.
•
Start with the lower wheel that has the least
radius (crown), then increase the wheel radi
us a step at a time until the desired curve is
reached.
•
Practice with a scrap piece that is the same
material and thickness as the final operation.
•
Leave a frame around the workpiece of
approximately 1" that does not go through
the wheels. as the center of the workpiece
stretches and the frame does not, the metal
is forced to bend into a curve.
•
Take your time. Many passes through the
wheels with gradual increases in pressure
and lower wheel radii will produce good
results and reduce the risk of damaging the
workpiece surface.
•
Overlap each pass with the previous one in
a back-and-forth, smooth movement through
the wheels. t here are many patterns of
tracking that will produce different results.
Choosing the correct pattern for your opera
tion is a matter of research and experience.

SAFETY WARNINGS
Basic Operations
The individual results from using an English wheel
are countless. Practice, read books/internet sites,
watch videos, and seek advice from experienced
wheelers to gain necessary knowledge and expe
rience to produce good results.
The procedure below is an example of a very
basic operation.
To use the English wheel:
1. Make sure the frame is firmly secured in a
bench-mounted vise that is solidly attached
to a bench or table that will support the
weight and pressures of the operation.
2.
Put on safety glasses, leather gloves, and
steel-toed boots.
3. Deburr the sharp edges of the workpiece
(see Accessories on Page 15 for an optional
deburring tool).
4. Mark a frame around the workpiece of approx
imately 1 ".
5.
Clean the wheels to remove any abrasive
material that could damage the surfaces of
the workpiece or wheels.
6.
Install the lower wheel with the least radius
(crown).
7.
Use the lower wheel adjustment screw to
raise the lower wheel up, leaving enough
room to insert the workpiece between the
wheels.
8.
Insert the workpiece between the wheels and
adjust the lower wheel so that the wheel pres
sure is just enough to prevent the workpiece
from skipping or slipping through the wheels.
-14
-
6.
Move the workpiece back and forth through
the wheels in an overlapping pattern (see
example in Figure 11 ).
Note: is example is just one of many pat
tes of tracking.

7. When the workpiece no longer stretches,
rotate the lower wheel adjustment screw
clockwise to slightly increase the pressure.
8.
When maximum wheel pressure is reached
and the workpiece no long moves through the
wheels, change the lower wheel to the next
highest radius.
