maximum depth of cut, and should extend out 12 inches

or more to one side or the other depending on which

miter gauge slot is being used. This auxiliary wood-

facing (B) can be fastened

to the front of the miter

gauge by using two wood screws (C) through the holes

provided in the miter gauge body and into the wood-

facing.

NEVER USE THE FENCE AS A CUT-OFF

GAUGE WHEN CROSS-CUTTING.

When cross-cutting a number of pieces to the same length, a

block of wood (B) Fig. 39B can be clamped to the fence and

used as a cut-off gauge as shown in Fig. 39B. It is important

that this block of wood always be positioned in front of the saw

blade as shown. Once the cut-off length is determined, secure

the fence and use the miter gauge to feed the work into the

cut. This block of wood allows the cut-off piece to move freely

along the table surface without binding between the fence and

the saw blade, thereby lessening the possibility of kickback and

injury to the operator.

WHEN USING THE BLOCK (B) FIG. 39B,

AS A CUT-OFF GAUGE , IT IS VERY

IMPORTANT THAT THE REAR END OF

THE BLOCK BE POSITIONED SO THE

WORK PIECE IS CLEAR OF THE BLOCK

BEFORE IT CONTACTS THE BLADE.

Ripping is cutting lengthwise through a board. The rip

fence (A) Fig. 40 is used to position and guide the work.

One edge of the work rides against the rip fence while

the flat side of the board rests on the table. Since the

work is pushed along the fence, it must have a straight

edge and make solid contact with the table. The saw

blade guard must be used. The guard has anti-kickback

fingers to prevent kickback and a splitter to prevent the

wood kerf from closing and binding the blade.

RIPPING

1. Start the motor and advance the work holding it down

and against the fence. Never stand in the line of the saw

cut when ripping. Hold the work with both hands and

push it along the fence and into the saw blade (Fig. 40).

The work can then be fed through the saw blade with

one or two hands. After the work is beyond the saw

blade and anti-kickback fingers, the hand is removed

from the work. When this is done the work will either

stay on the table, tilt up slightly and be caught by the

end of the rear guard, or slide off the table to the floor.

Alternately, the feed can continue to the end of the table,

after which the work is lifted and brought along the

outside edge of the fence. The cut-off stock remains on

the table and is not touched until the saw blade has

stopped, unless it is a large piece allowing safe removal.

When ripping boards longer than three feet, use a work

support at the rear of the saw to keep the workpiece

from falling off the saw table.

2. If the ripped work is less than 4 inches wide, a push

stick should always be used to complete the feed, as

shown in Fig. 41. The push stick can easily be made from

scrap material as explained in the section

“CONSTRUCTING A PUSH STICK.”
