Loose tenon joinery, on the other hand, provides all of the strength
benefits without the tedious setups. In loose tenon joinery all of
the pieces to be joined receive an identical mortise, while the tenon
itself is simply a short cutoff from a long piece of stock which has
been thickness planed, ripped and rounded over to fit the mortise,
Fig. 2. And, while locating the mortises at a router table is still
a problem using conventional methods, you’ll find perfectly located
slots easy with this new slot-mortising jig. The STS Slot Mortiser
takes advantage of the ease of vertical router adjustment provided
by the wave of router lifts on the market today. If you own a router
lift and a router table with a miter slot, you’ll love the versatility and
ease of use of this great jig. Just clamp your material in place and
slide the jig back and forth between two stops as you slowly raise the
cutter using the lift’s crank handle.

ortise and tenon joinery as shown in Fig. 1 produces some of the
strongest connections between two pieces of wood but the setups
can be tedious. The mortises are difficult to place accurately at the
router table and the tenons, while easy enough with the right jig,
still require two sets of cuts to produce. First the shoulders
are cut using a miter gauge followed by the cheeks, which are
cut using a tenoning jig. And all of this to produce what amounts
to a square peg for a round hole. The tenons need to be rounded
or the mortises squared for the final assembly. We probably don’t
need to mention the additional challenge of making cuts at the table
saw that fit well into cuts made at the router table.

STS (Slot-Tenon-Slot) Mortiser Assembly
1. In typical router table cutting operations, router lifts are installed
in the table with the crank handle located so that it is between the
router bit and your router table’s miter slot. In order to use your
new STS Slot Mortiser, you’ll need to rotate the router lift in your
table opening so that the router bit is between the miter slot and the
crank handle,

CAUTION: ALWAYS RETURN THE LIFT TO THE ORIGINAL SETUP AFTER
USING THE STS SLOT MORTISER.

2. Attach the Miter Slider and (2) T-Slot Panel Connectors to one
of the Build-It Panels and place in your router table’s miter slot as
shown in,
Fig. 4. Adjust the Miter Slider for a smooth glide in the
miter slot. Cut the remaining Build-It Panel at your table saw to fill
the gap between the panel connector and your router lift’s crank
handle. Attach the panel.
