Crosscutting with
the Handsaw
|
A
crosscut saw is designed to cut across the grain of
a board. The teeth on a crosscut saw are like a
series of sharp knives. This type easily slices
through the wood fibers as the saw cuts across the
grain. A crosscut saw with large teeth is used for
rough work; one with fine teeth is used for finish
work.
This
sheet describes the procedure for crosscutting
stock to length. For other operations ask your
instructor or refer to one of the many texts
available.
|
NOTE: Always use caution when handling bladed
equipment.
Operation (Crosscutting):
Crosscutting is the operation during which the stock is cut
across the grain to achieve the desired length of the
material; There is a step by procedure identified below
along with illustrations.
-
Select a crosscutting handsaw.
NOTE: A crosscutting handsaw is distinguished by the
shape of its teeth. Verify the teeth are arranged
to give to rows of points.
- Verify the saw is sharp
by asking the instructor to check the blade prior to
operation.
- Inspect the stock to be
crosscut, ensure the stock is clear of any foreign
objects that could bind the blade while
operating.
-
Lay out a line on the stock using either a Try-square or
a T bevel.
NOTE: Inspect the board, verify which end of the board
is going to be scraped.
- Once
the line is in the correct location, clamp the stock down
securely. In the event of large stock, use saw horses to
place stock for the cut.
NOTE: Sawing should always be done on or with a solid
support to prevent vibration.
-
Grasp the saw with your right hand, with the thumb and
index finger extended along the two sides of the
handle.
NOTE: This helps guide the saw in a straight
line.
-
Stand with your forearm, shoulder and eye follow the line
of the saw blade.
NOTE: In using saw horse, place your knee on the piece
to be cut.
- With blade on the waste
side of the stock, start as close to the line as
possible.
- Grasp the edge of the
board with your opposite hand, place your thumb, high, on
the side of the blade to act as a guide while making the
cut.
- Start the saw with two
or three light upward strokes; this will engage the
teeth.
- Once the teeth are
engraved, take a few short strokes to deepen the
groove.
-
While removing the left hand, take full length strokes,
applying downward pressure with the arm and body.
NOTE: Applying wrist pressure results in a jerky
motion and will create difficulty to follow the
line.
- If you get off the line,
take short strokes, using the teeth at the toe of the
blade. Twist the blade slightly to bring the saw back to
the line.
- As the end of the cut
nears, the operator should grasp the stock with there
left hand and take short easy strokes until the saw has
completely cut through the work.
Note:
There are several other saws that can be operated while
using this procedure. Ask your instructor and refer to one
of the many references for those procedures.
The saw is being
held at the correct starting angle, ensuring the
blade has penetrated the wood before making full
cuts.
|
Keep a solid hold
of the stock that is not secured in the vice, while
maintaining a controlled cut.

Potential hazards:
Due to the sharp teeth on the crosscutting blade the
following hazards exist:
- Any body contact with
the moving blade will cause severe injury.
- Clothing or other
articles that contact the blade while making the cut
could become entangled and pull the operator into the
motion of the blade.
- Unsecured footing could
result in accident with the blade.
- Equipment not in working
order can result an injury.
- Distractions from shop
personnel could cause injury by misplacement of
hands.
Safety practices:
Because of those potential hazards the following safety
rules must be followed.
- Be sure to perform only
operations you know how to do safely.
- Always wear safety
glasses.
- Never wear cloths or
other articles that dangle and could catch on the
saw.
- Be sure to have firm
footing.
- Check the saw to make
sure it is in good working order.
- Check the stock for
foreign objects.
- Avoid distractions,
never look away during a cut.
- Do not allow others to
crowd around the saw.
- Never let go of the
stock during the cut.
