Ripping is cutting lengthwise through a board. The rip fence (A) Fig. 62 [not supplied] 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. On Delta saws, the guard has anti-kickback fingers to prevent

kickback and a splitter to prevent the wood kerf from closing and binding the blade.

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. 62).

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. 63. The push stick can easily be made from

scrap material as explained in the section

“CONSTRUCTING A PUSH STICK.”

3. Ripping narrow pieces can be dangerous if not done

carefully. Narrow pieces usually cannot be cut with the

guard in position. If the workpiece is short enough, use a

pushboard. When ripping material under 2 inches in

width, a flat pushboard is a valuable accessory since

ordinary type sticks may interfere with the blade guard.

When using a pushboard, the width of the pushboard

must be added to the width of the rip fence position

setting. A flat pushboard can be constructed as shown in

Fig. 65 and should be used as shown in Fig. 64.

NOTE: Some special operations (when using the

moulding cutterhead) require the addition of an auxiliary

wood facing to the fence, as explained in the section

“USING AUXILIARY WOOD FACING ON THE RIP

FENCE” and use of a push stick.
