Special Cuts - DeWalt DW705 Manual De Instrucciones

The chart on this page gives the proper settings for cutting
crown molding. (The numbers for the miter and bevel set-
tings are very precise and are not easy to accurately set
on your saw.) Since most rooms do not have angles of pre-
cisely 90 degrees, you will have to fine tune your settings
anyway.

INSTRUCTIONS FOR CUTTING CROWN MOLDING
LAYING FLAT AND USING THE COMPOUND FEATURES
1. Molding laying with broad back surface down flat on
saw table (Fig. 26).
2. The settings below are for All Standard (U.S.) crown
molding with 52° and 38° angles.
BEVEL SETTING TYPE OF CUT
LEFT SIDE, INSIDE CORNER:
33.85° 1. Top of molding against fence
2. Miter table set right 31.62°
3. Save left end of cut
RIGHT SIDE, INSIDE CORNER:
33.85° 1. Bottom of molding against fence
2. Miter table set left 31.62°
3. Save left end of cut
LEFT SIDE, OUTSIDE CORNER:
33.85° 1. Bottom of molding against fence
2. Miter table set left 31.62°
3. Save right end of cut
RIGHT SIDE, OUTSIDE CORNER:
33.85° 1. Top of molding against fence
2. Miter table set right 31.62°
3. Save right end of cut
When setting bevel and miter angles for all compound
miters, remember that:
The angles presented for crown moldings are very
precise and difficult to set exactly. Since they can
easily shift slightly and very few rooms have exact-
ly square corners, all settings should be tested on
scrap molding.

ALTERNATIVE METHOD FOR CUTTING
CROWN MOLDING
Place the molding on the table at an angle between the
fence and the saw table, as shown in Figure 26A. Use of
the crown molding fence accessory (DW7054) is highly
recommended because of its degree of accuracy and con-
venience. The crown molding fence accessory is available
at extra cost from your local dealer.
The advantage to cutting crown molding using this method
is that no bevel cut is required. Minute changes in the miter

angle can be made without affecting the bevel angle. This
way, when corners other than 90 degrees are encoun-
tered, the saw can be quickly and easily adjusted for them.
Use the crown molding fence accessory to maintain the
angle at which the molding will be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING
ANGLED BETWEEN THE FENCE AND BASE OF THE
SAW FOR ALL CUTS
1. Angle the molding so the bottom of the molding (part
which goes against the wall when installed) is against
the fence and the top of the molding is resting on the
base of the saw, as shown in Figure 26A.
2. The angled "flats" on the back of the molding must rest
squarely on the fence and base of the saw.

Special Cuts

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS
SECURED ON THE TABLE AND AGAINST THE
FENCE.
Aluminum Cutting:
Certain workpieces, due to their size, shape or surface
finish, may require the use of a clamp or fixture to prevent
movement during the cut. Position the material so that you
will be cutting the thinnest cross section, as shown in
Figure 27. Figure 28 illustrates the wrong way to cut these
extrusions. Use a stick wax lubricant when cutting
aluminum. Apply the stick wax directly to the saw blade
before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial
mill supply houses, provides proper lubrication and keeps
chips from adhering to the blade.
Be sure to properly secure workpiece. Refer to page 3 for
correct saw blade,
Bowed Material:
When cutting bowed material always position it as shown
in Figure 29 and never like that shown in Figure 30.
Positioning the material incorrectly will cause it to pinch
the blade near the completion of the cut.
Cutting Plastic Pipe or Other Round Material
Plastic pipe can be easily cut with your saw. It should be
cut just like wood and CLAMPED OR HELD FIRMLY TO
THE FENCE TO KEEP IT FROM ROLLING. This is
extremely important when making angle cuts.
Cutting Large Material
Occasionally you will encounter a piece of wood a little too
large to fit beneath the blade guard. A little extra height can
be gained by rolling the guard up out of the way, as shown
in Figure 25. Avoid doing this as much as possible, but if
need be, the saw will operate properly and make the big-
ger cut. NEVER TIE, TAPE, OR OTHERWISE HOLD THE
GUARD OPEN WHEN OPERATING THIS SAW.
