AUXILIARY TABLE BOARD FACING

To prevent repeated cutting into the table surface which will eventually cause the table to sag, an auxiliary table board

facing can be cut and fitted to the table. It can be made from 1/4" plywood or particle board and should be cut to a

size that will exactly cover all of the table boards in front of the fence. The auxiliary table board facing should be placed

flat on the table and butted against the table fence. Fasten it to the table with a small brad or finish nail in each corner.

The life of the table boards will be greatly extended by the use of an auxiliary facing.The auxiliary facing can readily be

replaced as often as is necessary to protect the table boards and to insure accurate and safe work.

USING A TABLE EXTENSION

When a table extension more than 24 inches long is attached to the saw, a sturdy outrigger support should be provided

or the stand or bench must be secured to the floor.

OPERATIONS

CROSS-CUTTING

The first operation which should be learned on the radial

saw is cross-cutting (Fig. 76). Cross-cutting consists of

supporting the workpiece against the fence and pulling

the saw blade through the material at right angles to it.

When cross-cutting, the track arm should be indexed at

“0” and the track arm clamp handle tightened. The fence

should be clamped between the table boards. The saw

blade is to be to the left and behind the fence. The

workpiece is placed on the table and butted against the

fence. The saw blade should be clear of the fence and

table when the machine is turned on. Then the saw blade

is lowered until it lightly cuts into the table surface. The

operator should position himself a little to the left of the

machine for better visibility while cutting. Pull the saw

blade across the work, just far enough to cut it off, and

return the saw blade to its starting position. Turn tool off.

and wait for the blade to stop before touching the cut-off

piece. CAUTION: The operator must always be

conscious of where his hands are; that they are clear of

the blade and holding the workpiece firmly. As an added

measure of operator safety, since the splitter and anti-

kickback fingers are not used in the cross-cutting oper-

ation, the anti-kickback rod can be turned upside down

and locked in place so the rod just clears the workpiece.

In this position the rod can act as a guard from the

exposed teeth of the blade. Fig. 76 shows a cross-

cutting operation on a radial saw.The operator should

always be sure to return the cutter-head carriage to the

full rear position after each cross-cut operation.

NOTE: When cross-cutting material more than 1"

thick, the fence must be positioned immediately

behind the fixed front table board.

CROSS-CUT STOP

A block of wood (B) Fig. 77, clamped to the track arm with

a small clamp will prevent unnecessary travel of the

cutting-head on the track arm. This is especially useful

when performing repetitive operations. Clamp the block

of wood to the right side of the track arm at a position

which will stop the cutting-head travel as soon as the saw

blade cuts through the workpiece.

MITER CUTTING

Miter cutting is similar to cross-cutting except the

workpiece is cut off at an angle (up to 45 degrees right or

left) rather than being cut off square. The settings and

operation are performed in the same manner as cross-

cutting except that the track arm is first positioned to the

desired angle on the miter scale before it is clamped in

place. The operator should position the hand holding the

workpiece on the opposite side to the direction of the

miter so the blade is pulled through the workpiece and

away from the hand. Fig. 78, shows a typical miter cutting

operation on the radial saw.
