Epson 36-714 instruction manual Ripping, Push Stick

RIPPING

Ripping is cutting lengthwise through a board, (Fig. 45). 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. 45). 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. 46. 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 - YOU CAN 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. 47 and should be used as shown in Fig. 48.

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.
