INSTALL AND ALIGN THE
CUTTING TOOL
The cutting tool consists of two blades, a left and a
right hand blade. Install blades in proper left and
right hand positions and clamp in place using locking
screws and small hex wrench.
Hold a steel straight edge against the blades and
view from above. If the blades are not properly
aligned, loosen locking screws, realign, and tighten.
Check alignment periodically during operation. BE
SURE no sawdust gets into the blade slot as proper
alignment will not be possible. See "POSITIONING
THE CUTTING BLADES" for proper blade
alignment.
HOW TO DETERMINE THE
CUTTING ANGLE
There are two variables involved in the proper
cutting angle: thickness of the wood and thickness of
the cut. The index plate controls the thickness of the
cut to a 5/16" increment.
To calculate the cutting angle, draw a straight line
vertically on a sheet of paper, place your wood on
edge perpendicular to the line and draw a line on each
side of the wood (See FIGURE 4). Measure 5/16"
along the top line and mark point "B". Draw a line
between points "A" and "B" and measure angle "X"
with a protractor. This is your cutting angle for that
thickness of wood.
If you are cutting 3/4" wood the angle is about
22- 1/2°, and EVERY TIME YOU CUT 3/4" wood
the angle will be the same. The cutting angle for
1/2" wood is about 32 ° and 3/8" about 39 1/2 °.
Cutting Angle To Use
Wood With Index Plate
Spacing:
Thickness
5/16" 3/8"
1/4" 51.1° 56.3°
5/16" 44.8° 50.2°
3/8" 39.6° 45°
7/16" 35.3° 40.6°
1/2" 31.8° 36.9°
9/16" 28.9° 33.7°
5/8" 26.4° 30.9°
11/16" 24.3° 28.6°
3/4" 22.5° 26.5°
13/16" 20.9° 24.8°
7/8" 19.5° 23.2°
Once the cutting angle has been calculated, align the
degree setting on the swing plate with the scribe line
on the slide plate. Lock the swing lock.
FIGURE 4
POSITIONING THE CUTTING
BLADES
Unlock the slide lock, slide assembly forward and position
cutting blades until both left and right blades will engage the
wood. Locate the nearest index stop with the index pin.
Unlock the index plate lock screw and move index plate to the
rear, and tighten the lock screw. Lock slide lock. To adjust
swing plate reference #34, loosen front slide plate lock bolt,
reference #28, loosen swing plate lock bolt, reference #29.
Adjust swing plate to desired angle and tighten.
BY HAND, rotate wood one full revolution to insure that
both left and right blades will engage wood. See FIGURE 5.
If you find that the left blade will not engage the wood, unlock
slide lock, remove index pin and slide forward to engage the
NEXT index hole. Replace index pin and lock slide lock
.
