3. Attach the stop positioner to the fence using 1/4 -20 x 1” hex bolts with washers and clamping knobs, then attach the fence to the
Build-It Platform using (2) Build-It Brackets with the included
1/4 -20 x 1” hex bolts, washers and clamping knobs. Square the
fence to the “cut” edge of the Built-It Platform and tighten the
clamping knobs,

4. Attach the 18” T-Track Plus to the faceplate using the #8
x
1/2 ” Phillips pan head screws, then glue up the right angle
faceplate assembly as shown, Fig. 6. The right angle supports
will sit in the grooves located on the base, Fig 7.
5. Secure the right angle faceplate assembly to your Build-It
Platform using (2)
1/4 -20 x 1- 1/2 ” hex bolts with washers and
clamping knobs as shown in Fig. 8. Slide the slotted base of
the faceplate assembly up to the fence and tighten the clamping
knobs. Attach the (2) faceplate stops to the assembly using (2)
1/4 -20 x 1- 1/2 ” hex bolts with washers and clamping knobs, Fig 9.

Operation
Set Length of Slot
To set the length of your slot, raise the cutter through
the slotted hole in the throat plate panel and slide
the faceplate assembly up to (but not touching) the cutter.
Before tightening the faceplate assembly clamping
knobs, make sure that it is pressed securely against the
fence. Slide a faceplate stop into each end of the T-Track
on the faceplate. In setting the stops, you will always
use the 8” mark on the faceplate scale to represent the
“center” of your slot length.
To set up for a 2” long slot,
set the outfeed faceplate stop
to 7” and the infeed stop to 9”.
In other words, the distance
between the two stops is
equal to your slot length,
Fig. 12.
Fig.12 Setting Slot Length
For typical slot mortising there are four steps to locating a slot on your workpiece.
Step 1
Fig.11 Slot Length
For your first mortise, you’ll cut a slot about 4” long through the “throat plate” Build-It Panel that overlaps the cutter at your
router table. Since most loose tenon applications in
3/4 ” stock work well with a 3/8 ” tenon, we’ll cut the slot with a 3/8 ” straight
bit. (The longer the cutter length, the deeper
you’ll be able to cut your slot mortises later on.)
Install the cutter and lower the bit below your
tabletop. Place the STS Slot Mortiser on your
router table and center it on the length of your
miter slot. Now clamp a
3/4 ” x 3/4 ” x 3” block
of wood into the infeed and outfeed ends of
the miter slot 2” from the ends of the Miter
Slider,
Fig. 10.
Slide the right angle faceplate assembly and
T-Track fence away from the area directly
above the cutter and turn the router on. Use
your router lift crank handle to raise the cutter
1/16” per pass as you slide the jig back and forth
between the two stop blocks clamped to the
table.
CAUTION: ALWAYS START AND STOP ANY
SLOT CUTTING OPERATION WITH THE JIG
POSITIONED AGAINST THE OUTFEED STOP
BLOCK.
When you have cut through the throat
plate, turn off the router. The throat plate provides support for your workpiece and zero clearance for tear out control. If you
choose to cut mortises with a larger or smaller diameter cutter, additional throat plates can be produced. Your new STS Slot
Mortiser is now ready to use.
Set distance between stops equal
to desired slot length
(use 8” mark on scale as center)
