6.
With the fence now set to the correct front to back
position, tighten the two fence locking levers to
hold the fence in place.
7.
So that the chips are discharged into the part of
the mortise which is already cut, and that the part
to be cut remains well visible, set the workpiece on
the table with the bit aligned with either:
-
The left end of the mortise if the chip clearing slot is
facing left
;
-
The right end of the mortise if the chip clearing slot
is facing right
;
NOTE: To avoid overheating or damage to the chisel or bit,
do not position the slot against the blind end of the mortise
as this would prevent the chips from discharging from the
chisel.
8.
If multiple workpieces are to be mortised in an
identical manner, adjust the workpiece stop
to
allow to position the next workpiece at the exact
same location.
9.
Tighten the workpiece clamp
to hold the work-
piece securely against the fence.
10.
Lower the workpiece hold down until slightly above
the workpiece
and tighten.
11.
Turn on the machine.
12.
Lower the chisel into the workpiece
using a
steady even pressure until it bottoms out on the
depth stop.
FEED RATE:
NOTE: To prevent burning of the tip of the bit, a steady feed
rate is required. The machine may stall or slow down if the
feed rate is too fast
TIP: To allow chips to discharge when cutting deeper mor-
tises or through mortises, cut the mortise to its full depth in
several steps, by backing off periodically at roughly 3/8”
– 1/2” intervals. Raising the bit back out of the mortise
briefly, before plunging back in, allows the chips to dis-
charge more easily and can contribute to longer chisel
and bit life and cleaner sharper mortises.
When cutting through mortises, place a piece of scrap
wood under the workpiece to help prevent tear-out as the
bit cuts its way through the opposite or exit face of the
workpiece.
13.
Raise the chisel.
14.
Loosen the workpiece clamp slightly, and reposi-
tion the workpiece against the fence to continue
the cut.
TIP: For added convenience and time savings when cut-
ting longer mortises, optional rollers, item 75-055 (avail-
able from your General® International dealer) can be
used instead of the workpiece clamp, allowing you to
“roll” the workpiece left or right
as needed to continue
the next cut for the mortise slot.
15.
Re-tighten the workpiece clamp.
16.
Continue cutting the mortise.
17.
Repeat to complete the mortise overlapping each
cut slightly
.
18.
Test the fit of your tenon in the mortise
. Re-adjust
if needed.
