MATCHFIT JIG
Tall Fence + Jointing Sled + Tapering Jig

1
This 3-in-1 jig serves as a tall fence, a jointing sled, and a tapering jig, all made possible by the
MATCHFIT System. When secured with Dovetail Clamps to a table saw, router table, or
bandsaw fence, it provides added support to cut material on its edge. Laid flat on the table
saw top, you can clamp warped or live edge material to it and safely cut a straight edge,
running the sled along the fence. By adding simple stops with Dovetail Hardware, you can set
the material at an angle and make safe, repeatable taper cuts.

STEP 2 - ROUTE RELIEF GROOVES
2
On the table saw, cut a sheet of 3/4” thick plywood 10” wide x the length of your
table saw’s rip fence.
On the router table, set a 1/4” diameter straight or spiral router bit to a cutting
depth of 11/32”. Set the fence to 2” and route relief grooves along both long sides.

Next, move your fence to 4”, and route relief grooves on the two short sides. Now
mark the center of the sled longways, and route a groove down the center. If your
router table doesn’t have enough capacity, remove the fence and use a miter
gauge. Now measure the halfway point between the center groove and the outer-
most grooves on your sled, and route the last two grooves.

STEP 2 - ROUTE RELIEF GROOVES CONTINUED
*NOTE* If your router table fence has less than 4” capacity, you can use an auxiliary
fence. CLICK HERE for instructions on how to set up an auxiliary fence on your
router table.

On the router table, set a 1/2” 14-degree dovetail router bit to a cutting depth of
3/8” (.375). Route dovetail tracks in the same locations as the relief grooves in the
previous step.
Chop an inch off of each corner at 45 degrees and chamfer the two short sides and
one long side.

STEP 3 - ROUTE DOVETAIL TRACKS
STEP 4 - CHAMFER

Cut (2) blocks out of 1/2” thick plywood, 2” wide x 6” long. Route 1/4” wide slots
and heels according to the schematics below.

STEP 5 - CUT TAPERING JIG STOPS

Insert MATCHFIT Dovetail Clamps in the outermost 10” long dovetail tracks. Place
the edge of the jig on the table with the routed side against the fence, then clamp
the sled to the rip fence.
OPERATION

AS A TALL FENCE

Lay the sled flat on the table saw top with the routed side facing up. Align the edge
you want to cut with the edge of the sled closest to the blade. Adjust the rip fence
so that the edge of the sled is only 1/16-1/8” from the blade. Secure your work-
piece with Dovetail Clamps, and make the cut, using the clamp bars as handles.
OPERATION

AS A JOINTING SLED

Mark your taper cuts on the workpiece, then place it on the jig with the marked line
aligned with the unchamfered edge of the sled.
Once your workpiece is aligned, place the slotted stops up against two sides of the
workpiece and lock them in place with MATCHFIT Dovetail Hardware. Make sure
that every piece is contacting the stops to ensure uniformity. Clamp workpiece in
place with MATCHFIT Dovetail Clamps and advance sled along the fence through
the cut.
