RIPPING is sawing wood with the grain, using the
fence to guide the work. Mount a rip or combina-
tion blade on arbor. Position fence for width of cut
desired. The blade should be set high enough so
that several teeth project above the work - this
helps the blade to free itself of sawdust. Hold the
work firmly against the fence to guide it in the saw-
ing operation - see Figure 11. If work is long and
wide - for example, panels - it often helps to fol-
low a pencil line to obtain an accurate cut.
CAUTION: If the space be tween the blade and
lhe fence is narrow, use a V-shapecl push stick to
feed the work past the blade - see Figure lZ.
CROSSCUTTING is sawing wood ac1·oss the grain.
Use the mitre gauge to guide and help hold the
work accurately and safely in the sawing operation.
Remove rip fence. Mount a crosscut or combination
blade on the arbor. The blade should be set high
enough so that several teeth project above the work
- this helps blade to free itself of sawdust. Hold
the work firmly against mitre gauge to guide it
past the blade - see Figure 14. Use the extension
rods in the mitre gauge to simplify duplicate wo1·k
- see Figure 13.

When blade is tilted for angle cuts, the mitre
gauge can be used on either side of the blade. Use Figure

a protractor to set the blade angle for close toler-
ance work.

CAUTION: If blade guard is used and blade is tilted
beyond 35°, use mitre gauge on right side of blade only.
DADOING, RABBETING AND MOULDING
Dado and rabbeting joints are used in steps, shelves,
drawers and furniture construction.
The 6" Dado Head, No. 2915 , equips the s aw io
cut dado and rabbeting joints a nd grooves up to
13/ 16" wide - see Figures 15 and 16. Dado Head
replaces the saw blade and consists of two outside
saws and various width chippers that are placed
between the saws to cut width of groove desired.
Always use the chippers between the blades , never
alone. Dado and moulding operations require a
Dado In se rt Plate , No. 306858. To s et up, remove the
in~ert pl~te, blade guard and splitter. Then place
chippers m between the blades to obtain the desired
width . Place unit on saw arbor - first the outside
blade, then the chip-
with the nut only. Figure 17
Feed the work with
a firm, even pressure to obtain accurate and smooth
grooves. Use the mitre gauge or fence to guide
the work .
Mouldings and dados may be cut using a Dado-
Moulding Head (No. 307097, Figure 17). This tool uses
interchangeable cutters and a variety of shapes ate
Figure 15 Figure 16
Figure 18 Figure 19
available to cut dados, rabbets, middle laps, end laps, cross laps -
all straight moulding jobs such as fluting, channeling, beading, joint-
ing and glue joints. As with the dado head, the insert plate, No.
306858, must be used with the saw guard Md splitter removed.
An auxiliary wood facing, bolted to fence is sometimes necessary
when cutting shapes requiring only part of the blade - see Figures
18 and 19.
