3. To decrease the depth of the mortise (female) cut,
turn the bolt clockwise. To increase the depth of
the mortise cut, turn the bolt counterclockwise.
4. Re-tighten the hex nut.
Thickness of Tenon Cut
To adjust the thickness of the tenon (male) cuts, you
will change the depth of the tracer pin (A, Figure 20).
1. Disconnect machine from power source.
2. Loosen the locking handle (B, Figure 20).
3. Insert a 5.5mm hex wrench into the end of the
adjustment screw (C, Figure 20) and turn the
adjustment screw as needed. To decrease the
thickness of the tenon cut, turn the adjustment
screw counterclockwise. To increase the thickness
of the tenon cut, turn the adjustment screw
clockwise.
4. Tighten locking handle (B, Figure 20).
Tightness of Mortise / Tenon Fit
A proper dovetail fit should be snug with no gaps
showing, but not overly tight as glue must later fill the
joints. If the cuts seem correct, but the joint is simply
too tight, or the joint is too loose, proceed as follows.
1. Disconnect machine from power source.
2. Remove the dust hood from the front of the
headstock. Release one end of the spring on the
headstock (see Figure 12) and pull the headstock
away from the machine until the cutter becomes
more accessible.
3. You will notice the cutter, shown in Figure 21, is
slightly off center of the spindle. The spindle is
eccentric and allows the cutter to be turned to a
different position on the spindle.
The cutter is very sharp!
Use caution when working with or around it.
4. Loosen both set screws on the spindle (Figure 21
by turning them counterclockwise with a 4mm hex
wrench.
5. A scale is located just above the cutter, with a plus
(+) and minus (-) sign. Moving the cutting edge of
the cutter toward the plus (+) side of the scale will
increase the size of the mortise cut and decrease
the size of the tenon cut. Moving the cutting edge
of the cutter toward the minus (-) side will decrease
the size of the mortise cut and increase the size of
the tenon cut.
