1. Make splitting cuts about 2 feet (60 cm) long,
leaving 2 inches (5 cm) of undisturbed metal between
all cuts and at the end of the beam (fig. 3-38). As the cut
is made, cool the steel behind the torch with a water
spray or wet burlap.
2. After splitting cuts have been made and the
beam cooled, cut through the metal between the cuts,
starting at the center of the beam and working toward
the ends, following the order shown in figure 3-38.
The procedure for splitting abeam also works very
well when splitting plate and is recommended when
making bars from plate. Multiple cuts from plate can
be made by staggering the splitting procedure before
cutting the space between slits. If this procedure is
used, ensure that the entire plate has cooled so that the
bars will not warp or bend.
When a part must be produced in quantity, a
template is made first and the job laid out from the
template. A template is any pattern made from sheet
metal, regular template paper, wood, or other suitable
material, which is used as a guide for the work to be
done. A template can be the exact size and shape of
the corresponding piece, as shown in figure 3-39,
