RIPPING

Ripping is cutting lengthwise through a board, (Fig. 49).

NOTE: Be sure the material to be cut is seasoned, dry and

flat. The rip fence (A) 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. Be sure to replace

or sharpen the anti-kickback devices when the points

become dull.

A rip fence should always be used for

ripping operations. NEVER

perform a ripping operation

free-hand.

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. When the rip width is 6 inches or wider,

hold the work with both hands and push it along the

fence and into the saw blade (Fig. 49). The work should

then be fed through the saw blade with the right hand.

Only use the left hand to guide the workpiece. Do not

feed the workpiece with the left hand. After the work is

beyond the saw blade and anti-kickback fingers, remove

hands from the work.

2. 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.

3. If the ripped work is less than 6 inches wide, a push

stick should always be used to complete the feed, as

shown in Fig. 50. The push stick can easily be made

from scrap material as explained in the section

“CONSTRUCTING A PUSH STICK.”

4. Ripping narrow pieces can be dangerous if not done

carefully.

When the piece is too narrow for a push

stick to be effective - and if the workpiece is short

enough - use a pushboard. When ripping material under

2 inches in width, ordinary push 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. 51 and

should be used as shown in Fig. 52.

NOTE: Guard removed for clarity. Always use the guard.

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” and use of a push stick.
