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 (A) Fig. 63, is first positioned to the desired angle on the miter scale before it is clamped in place with clamp handle (B). 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. 63, shows a typical miter cutting operation on the radial saw.

COMPOUND MITER

CUTTING

Compound miter cutting is performed in the same manner as miter cutting except the saw blade is also tilted to cut a bevel. The settings and operation are similar to miter cutting except that the blade is first tilted to the desired angle on the bevel scale before it is clamped in place. Fig. 64, shows a compound miter cutting operation on the radial saw.

RIPPING

Ripping involves making a lengthwise cut through a board along the grain. When ripping, the track arm (B) Fig. 65 and 66, are clamped at “0” on the miter scale. The yoke is then positioned and clamped so that the blade is parallel to the fence in either the inboard or outboard position.When feeding the material, one edge rides against the fence while the flat side of the board rests on the table. The guard should be lowered on the infeed side until it almost touches the workpiece, as shown in Figs. 65 and 66, to act as a holddown. The splitter and anti-kickback fingers (A) Fig. 65, should be adjusted accordingly. The operator’s hands should always be well away from and to the side of the blade. When ripping narrow work, always use a push stick as shown in Fig. 66, to push the work between the fence and blade. NOTE: The workpiece must have one straight edge to follow the fence. If board is bowed, place hollow side down. IMPORTANT: The cuttinghead clamp knob

(C)Figs. 65 and 66, should be securely tightened for all ripping operations. Pay particular attention to warning label which states that material must never be fed into the outfeed end of the blade guard.

OUT-RIPPING

Out-ripping involves all of the general conditions stated under RIPPING. The yoke is clamped at right angle to the track arm with the blade guard facing the front of the machine. The cuttinghead is positioned on the out-rip scale to the desired setting and clamped in position. The workpiece is fed from the left side of the saw. Fig. 65, shows a typical out-ripping operation on the radial saw.
