Thank you for purchasing General Tools & Instruments’ DOVETAILER Dovetail Jig. A simple and
easy way to make professional dovetail joints, the DOVETAILER enables you to cut half blind, full
through and box joints as well as edge to edge joining. The DOVETAILER can be used on a router
table (Fig. 1 or free hand with a hand-held router (Fig. 2).

Included bearings are 1/2 in. outside diameter (OD) and 1/4 in. inner diameter (ID). Router sleeves
or bushings can be used in place of the guide bearings as long as they are also 1/2 in. OD.
Included router bit is 14˚ x 1/2 in. Other bits can be substituted provided they have a 1/4 in.

saFeTY OvervIew
1. KNOW YOUR ROUTER. Read the owner’s manual that came with your router before
you use it. Understand the machine’s applications and limitations, as well as the
specific potential hazards inherent in its use. Before using the router, check that none
of its moving parts are broken, loose or misaligned.
NOTE: General Tools & Instruments is not responsible for router misuse or the disregard of
standard safety precautions associated with using a router.
UsInG THe BUIlT-In DePTH GaUGe
The built-in Depth Gauge is used to set both the depth of the Dovetail Cutter during router setup
as well as to control the length of the pins during cutting. (FIG. 5).
1. Loosen the Template Lock Screws
on the face of the Depth Plate
.
2. Align the Depth Measuring Working Surface with the desired measurement on the
Template Position Rule .Make sure both sides are at the same measurement.
3. Tighten the Template Lock Screws
to lock the Depth Adjuster Plate in position
.
rOUTer seTUP
1. Insert the dovetail cutter with
its guide bearings fully into the
router.
2. Set the height of the Dovetail
Cutter Bit using the Depth
Measuring Working Surface .
(FIG.6)
For nstruct ons on sett ng the
depth gauge see USING THE
DEPTH GAUGE above.

3. FIG.7 shows the dimension of the
dovetail joint affected by the
cutter height.
NOTE: Setting this height affects
the length of the Tails and the depth
of the Pins.
4. Now that the router is set up,
you need to reset the Depth
Adjuster Plate
for the length
of the pins. (FIG. 8) Set the
depth gauge for the length of
the “PINS”. This should be
equal to the thickness of the
wood used for the “TAILS”
board. (FIG. 9)
(''!"!'&
Note: Always cut the “TAILS” side of the joint first.
CUTTInG a HalF BlInD DOveTaIl JOInT
1. When cutting a half-blind dovetail joint, using the included
dovetail cutter, start with a bit height setting equal to the
depth of the joint you desire. (FIG. 7)
2. Cut a test joint with scrap wood to confirm the fit of the
joint. If the boards do not fit together easily, the joint
may be too tight. The joint can be made looser or
tighter by setting the cutter depth shallower or deeper
as shown in FIG. 8.
3. Mark the center of your board, then center the mark on
any one of the guide teeth in the “TAILS” portion of the jig.
4. Make sure the outside face of the board faces inwards
towards the clamp.
5. Tighten.

6. Clamp the board to a workbench or
secure it in a vice as shown (FIG. 10)
or if using a router table, make sure
the face saying “cut tails this side” is
faced to the router table (FIG. 11).
7. Cut the “TAILS” portion of the joint
always keeping the guide bearings
against the template edges. When
finished, remove “TAILS” board from
the jig.
8. Then to cut the “PINS”, loosely
clamp the “PINS” board into
the jig with the outside face
pointing inward.
9. To align the edges, insert the
tails of the “TAILS” board
into the Edge Alignment
Teeth on the top of the
Adjuster plate
with the
rounded side in (inside face),
and slide the loosely
clamped “PINS” board to
align its edges with the
edges of the “TAILS” board.
Now securely tighten the
clamps and remove the
“TAILS” board
(FIG. 12).

10. Make all cuts to the pins board. For those cuts, the router should ride on the surface
marked “cut pins this side” shown in FIG. 13 & 14. Be sure to follow the jig profile.
11. Dry fit the two sections together. If problems arise, file or trim the joint as needed.

CUTTInG JOInTs lOnGer THan THe JIG OPenInG
Joints longer than the opening must be cut in multiple continuous segments. To align the jig with
the previous cut, the aligning tool provided must be used.
1. Move the previously cut wood in the jig and position the last slot from the previous cut in
the last channel of the jig, either going to the right or to the left.
2. Loosely clamp the wood in the jig.
3. Insert the aligning tool into the slot to properly align the wood with the jig. (FIG. 15)
4. Tighten the clamps securely and continue cutting.
5. Repeat as necessary.

The steps required to cut a full through joint (FIG. 16) are the
same as to those described in the previous section CUTTING A
HALF BLIND DOVETAIL JOINT, with the following exceptions:
When cutting the “PINS” portion of the joint, set the depth
gauge equal to the thickness of the “TAILS” board.
