Evaluating Cutting Efficiency

Is the blade cutting efficiently? The best way to
determine this is to observe the chips formed by
the cutting blade.

If the chip formation is powdery, then the feed is
much too light, or the blade is dull.

If the chips formed are curled, but colored – blue
or straw colored from heat generated during the
cut – then the feed rate is too high.

If the chips are slightly curled and are not
colored by heat – the blade is sufficiently sharp
and is cutting at its most efficient rate.

Work Setup

Referring to Figure 8:

1. Set

the

feed rate control knob (C) to zero.

2. With the lifting handle (A) raise the saw

head (B).

3. Turn

the

vise handwheel (D) counterclock-

wise enough to free the moveable vise
jaw
(E). Then pull the moveable vise jaw
away from the fixed vise jaw (H).

4. Place the workpiece (F) on the work

table (G).

For long workpieces, provide support at the
other end. If necessary, provide additional
downward clamping to hold the workpiece
securely on the worktable.

5. Clamp

the

workpiece (F) in the vise by first

pushing the moveable vise jaw (E) against
the workpiece. Then rotate the vise hand-
wheel
(D) clockwise to secure the work-
piece.

Setting The Vise For Angle Cuts

Referring to Figure 9, the vise can be adjusted
through a 45-degree arc as follows:

1. Loosen

the

lock handle (E) that secures the

fixed vise jaw (D).

2. Rotate

the

fixed vise jaw (D) to the desired

angle, setting it to the scale on the back
edge of the table.

For accurate cuts, use a variable protractor
to set the position of the jaw, aligning one
side of the protractor with the blade.

3. Tighten

the

lock handle (E).

4. Loosen the hex head bolt (A) on the

moveable vise jaw (C).

5. Place the workpiece (B) between the vise

jaws (C, D).

6. Set

the

moveable vise jaw (C), pressing it

against the side of the workpiece (B) and
fixed vise jaw (D).

7. Tighten the hex head bolt (A) on the

moveable vise jaw to secure the jaw.

Setting the Vise for Square Cuts

The procedure for setting the vise for square
cuts is identical to setting for angle cuts (above)
except that a machinist’s square is used to set
the angle of the fixed vise jaw (J, Fig. 10). Align
one side of the square with the side of the slot
(G, Fig. 10) in the table.
