Your work surface should be absolutely
flat. Any unevenness may cause your glass to break. An uneven
work surface will also cause you to score unevenly, resulting in
breaks that do not follow the score lines. A workbench covered
with commercial or outdoor-type carpeting is ideal if you work
with large sheets of glass, but for most hobbyists, a thin
padding of newspaper is sufficient.
Keep your work surface free of small glass
chips. A small bench brush will do the job and prevent you from
being tempted to sweep away glass chips with your hands.
How to Hold Your Cutter.
Hold your cutter however it feels
comfortable for you. You may score away from or toward yourself.
It may feel a little awkward at first, but with a little practice
and experimenting, you will find a way that feels
"right" for you.
It does not take brute strength to cut
glass, since glass is not actually cut, it is scored. Exerting
about 15 pounds of pressure, the wheel of the cutter
"scratches" the glass, created a stress point. When
pressure is applied to this score line or stress point, the glass
should break along the line.
The care and use of
your cutter. Keep your cutter in
a jar filled with enough lubricant to cover the wheel. Pad the
bottom of the jar with a small piece of cloth or paper towel. It
is recommended that you store your cutter in this jar of
lubricant whenever it is not in use. Before each score, dip your
cutter in this solution.
Cutting the Glass.
- Stand to cut glass, so that you may
see what you are doing and so that you can get the proper
pressure from your shoulder rather than your wrist.
- Lubricate the cutter before you begin,
and between each score.
- When cutting stained glass, always
score the glass on its smoothest side.
- Hold the glass securely with one hand
while scoring with the other.
- Begin to cut 1/8" from the edge
of the glass.
- Maintain an even pressure while
scoring. Failure to do so could result in the glass not
breaking properly. Your score line should be visible, and
a gentle "ripping" sound should be heard. If
you don't hear or see it, pressure is too light. A heavy,
white, fuzzy line indicates that you are using too much
- Never go over the same score line.
Doing so will dull your cutter, and the glass will not
- Make sure the wheel is perpendicular
to the glass at all times. Slanting the wheel will give
you a beveled edge, or even worse, you will not be
scoring the glass at all.
- STOP SHORT of the edge of the glass
for longer cutter life.
- Always do the most difficult scores
- If you have to use excessive pressure
to score, your cutter is probably dull, or you are using
the wrong cutter for the type of glass you want to cut.
- If your score line looks like a dotted
line, the wheel of your cutter is probably dented, and it
should be discarded.
