Cutting Aides
Before cutting any wood on your saw, study
all of the Crosscutting
and Ripping instruc-
tions found on pages 45 through
57. As you
learn new radial arm saw woodworking
tech-
niques, you'lt see that many types of cuts
need different
support
and feeding devices,
known as jigs or fixtures.
They can help you
make cuts more accurately.
By helping to
steady the workpiece
and keep you away
from the blade, they can hetp you safely use
your saw for certain cuts. Many people
cus-
tom build their own jigs and fixtures. Jigs and
fixtures
are often designed
for a particular
cut. You can use your radial saw to easily
make many jigs and fixtures. To get you
started, we've included
instructions
for some
simpte ones. After you have made a few
practice
cuts, make up these jigs before
starting
any projects. Make the push stick
first.
Push Sticks
Make the push stick using a piece of 1 x 2.
(see drawing
top right for dimensions
and
shapes)
Push Block
There are any number of ways to properly
cut your work pieces to make a push block.
The following
steps describe
one way you
can proceed.
Making the base:
o Start with a piece of 3/8" plywood
at least
5-5/8" wide or wider and t2" long or longer.
• Make two ripcuts. Perform the first ripcut
along the long side of the 3/8" plywood to
create a 3/8" wide strip. Next ripcut the 3/8"
ptywood to a width of 5-1/8".
• Crosscut
the 3/8" plywood
to ! 2" long.
- Crosscut
a 2-1t2" piece off of the 3/8"
wide by 3t8" thick strip and save this short
piece for later.
- The next cuts wilt create the 3/8" by 9-1/2"
notch in the base. Mark the tong edge of
the board 2-1/2" from one end. Make a
crosscut into the edge, stopping about 3/4"
into the board. Set the saw to the in-rip
position and rip the width to 4-3/4" along
the same edge as the stopped crosscut.
Stop the ripcut where the two cuts inter-
sect. Turn off the saw and remove the base
piece. The base should now measure
as
shown.
