If you have not already done so, install
counterweights in the remaining two cutterhead
slots. The rabbet knife is locked in place with the
aluminum gib provided.
NOTE: When the rabbet knife becomes dull on
one side, move the rabbet knife and
counterweight set-up to the opposite side of the
cutterhead. This will give you a fresh cutting
edge with which to work.
Common Molding Applications
Practice and experience will greatly affect the
quality of molding that you produce. Once you
become familiar with the set-ups for the different
molding applications, you will easily be turning
out quality molding on every run. Some of the
more common applications are described below.
Back Relief
Back reliefs are used to create a better fit over
irregular surfaces. With less wood contact, the
molding matches irregular surfaces more easily.
See Figure 36. The back relief should be formed
on a piece of wood before it is molded to
finished thickness.
Rabbet
A rabbet is a rectangular cut on the corner of a
molding, as shown in Figure 37.
It is commonly used where pieces of wood are
being butted against and/or overlapped, such as
in ship lap and bevel siding. Always set your
guide against the side being rabbeted. The
rabbet cut should be completed before the
exposed side of the molding is finished.
Parting Bits
Parting bits will do a very smooth job of sawing
soft wood up to 3/4” thick. They are installed the
same as custom pattern knives with the planer
blades removed. More than one parting bit may
be used at one time. They can be placed as
close as 3/4” apart, and up to 10-7/8” apart.
Parting bits must be used in conjunction with a
bedboard as shown in Figure 38, as the bits will
cut into the bedboard so that they will cleanly
part the wood stock.
Crowns, Beds and Coves
Crowns, beds, and coves are made with custom
pattern knives. These moldings are made in two
passes. The molding is cut on both the top and
the bottom of the wood piece. See Figure 39.
Pass one is for the bottom. The beveled side
created mounts against the wall and ceiling.
Pass two creates the top which is the decorative
shape that is exposed to the eye when the
molding has been mounted.
