RIPPING

A RIP FENCE SHOULD ALWAYS BE

USED FOR RIPPING OPERATIONS. NEVER

PERFORM A RIPPING OPERATION FREE-HAND.

Ripping is the operation of making a lengthwise cut

through a board, as shown in Fig. 17, and 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 guard must be

used. The guard has anti-kickback fingers to prevent

wood kickback, and a splitter to prevent the wood kerf

from closing and binding the blade.

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 as shown

in Fig. 17. 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 rear end of the 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 back along the

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

the table and is not touched with the hands until the saw

blade is stopped, unless it is a large piece allowing safe

removal. When ripping boards longer than three feet, it is

recommended that a work support be used at the rear of

the saw to keep the workpiece from falling off the saw

table.

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. 18. The push stick can easily

be made from scrap material as explained in the section

“CONSTRUCTING A PUSH STICK.” When ripping

material under 2 inches in width, a flat pushboard is a

valuable accessory since ordinary push sticks may

interfere with the blade guard. The flat pushboard can be

made as shown in Fig. 19.

USING AUXILIARY WOOD

FACING ON RIP FENCE

It is necessary when performing special

operations such as moulding to add wood

facing (A) Fig. 20, to one or both sides of the rip fence, as

shown. The wood facing is attached to the fence with two

clamps (B). 3/4 inch stock is suitable for most work

although an occasional job may require 1 inch facing.

A wood facing should be used when ripping thin material

such as paneling to prevent the material from catching

between the bottom of the rip fence and the saw table

surface.
