INSTALL DOVETAIL BIT
Depending on the Dovetail Jig purchased, you will have
either a dovetail bit (1/2" diameter x 14º) with a 1/4" shank &
5/8" bearing (780), or a 5/8" Guide Bushing (5030), Locknut
(5040) and a dovetail bit (1/2" diameter x 14º) with a 1/2"
shank (61404). Install the bit (and bushing if applicable) in
your router and set the bit depth at 25/32". The depth may
need to be adjusted later after making a test cut. See fig. 14.
STOCK
This jig is designed for 3/8" to 1-1/8" thick stock. 1/2"
stock is the most common thickness used for drawers. The stock
used for the fronts & backs can be a different thickness then the
stock used for the sides. All stock should be flat and straight.
Stock thinner than 3/8" may be used for the backs and
fronts, but the ends of the pins (dovetails) may show. Using
thinner stock for the sides will not effect the look of the joint
like it will on the fronts and backs.
We recommend a 1/64" overhang on each end of the fronts
and backs, so cut the fronts and backs are 1/32" longer than the
finished width of the drawer. Cut the sides approximately 9/16"
longer (this will depend on the final cutting depth of the router
bit and only applies to the standard dovetail template) than the
desired inside length of the drawer.
The width of the stock will depend on the height of the
drawer opening, desired drawer depth and the dovetail pattern
selected.
Cut two pieces of stock for a test cut at least 8" long, 4-6"
wide and 1/2" thick. Follow the directions below for a standard
drawer. After you have mastered making a standard drawer you
may want to attempt a rabbeted drawer. See the RABBETED
DRAWER section for instructions on that process.

STANDARD DRAWER
Loosen the two ratchet handles on the two template
nuts and raise or lower the dovetail template at each
end until the drawer front (or back) just fits between the
underside of the dovetail template and the top edge of
the Ultra Track, then retighten the handles. Depending on
variations in the thickness of your stock, the dovetail template
height may have to be adjusted for each part. See 15.
Place a drawer side in the jig with the inside facing out, the
bottom edge against the stop and the end butted up against the
underside of the dovetail template. Slide the clamps as close as
possible to the edge of the part and tighten the clamps. See 16.
Slide the mating drawer front (or back) in between the
underside of the dovetail template and the top edge of the
Ultra Track, and slide it forward until it butts up against the
drawer side. The bottom edge of the part should be against
the pin in the stop and the inside face should be against
the template. Slide the clamps as close as possible to the
edge of the part and tighten them. The end of the drawer
side should be flush to top (inside face) of the drawer
front (or back). Check this with your finger between the
fingers of the dovetail template. See Cover & fig. 17.

MAKE A TEST CUT
Set the router on the
template (or, if using portably,
the Dovetail Jig on the router
table), without the bit touching
the work, template or router
support. Turn the router on and
make a scoring cut from right
to left (left to right if using
portably) across the face of
the drawer front by skimming
across the ends of the fingers.
The scoring cut helps prevent
chipping and tear out during
the finish cut. See fig. 18A.
Next, moving from left to
right (right to left if using
portably), move the router in and out of each dovetail finger
to finish the cut. If you get tear out, go a little deeper into the
template openings as you make the scoring cut to insure that
you have scored the entire face of the part. See fig. 18B.
In portable use you may notice that the thickness
of the dovetail template (7600T) and the thickness of the
clamp base (7600B1) are slightly different, which may
cause the two parts to not sit perfectly flat on a router
table. As long as you maintain downward pressure at the
dovetail template (and not the clamp base) using the feed
handles supplied, this will not make a difference.
Sometimes it’s necessary to make a second pass
due to sawdust that may have lodged in the template.
Remove the parts and check the joint fit.
JOINT FIT - DRAWER SIDE TO DRAWER FRONT
We recommend that the end of the drawer front (or back)
stick out past the drawer side l/64". This way the end of the
drawer front (or back) can be sanded or routed flush to the
drawer side after assembly. This also compensates for any
variation in the thickness of the drawer sides. You can also adjust
the template to cut the parts flush if you prefer. See fig. 19.
18A 18B
If the drawer sides stick out past the ends of the drawer
front (or back), then the template brackets/template must be
moved back, away from the face of the Ultra Track. If the
ends of the drawer front (or back) protrude past the drawer
sides more than 1/64", then the template brackets/template
must be moved forward slightly. See fig. 19.
The template brackets/template is adjusted in or out by
loosening the two 3/4" bolts holding the template brackets to the
template nuts. Make equal adjustments to both template brackets.
JOINT FIT - LOOSEN OR TIGHTEN
The pins (also known as dovetails - cut in the
drawer side) should slide into the sockets (cut in the
drawer front or back) with light tapping, at most.
If the joint is too loose, then the cutting depth
of the router bit is not deep enough. Adjust the bit
lower (more than 25/32") so it cuts deeper.
If the joint is too tight, then the cutting depth
is too deep and the bit needs to be raised (less than
25/32"). Bit set deeper than 25/32" = tighter joint.
Bit set shallower than 25/32" = looser joint.

STOP POSITION
The position of the stop controls the location for the groove
for the drawer bottom, which is normally centered in the first
dovetail socket from the bottom so it is hidden after assembly. The
bottom of the groove is usually between 1/4" (for side mounted
drawer glides) to 1/2" (for bottom mounted drawer guides) from
the bottom edge of the drawer. If you set the stop for a 1/4" margin, you may cut into the stop slightly, which is OK. Once you’ve
established the stop position needed, cut the drawer stock to a
width that will give you a full pin & socket at the top of the drawer. See fig. 20.
RABBETED DRAWERS
Rabbeted drawers are drawers with a face that over laps the
cabinet face. The other three drawer parts (both sides and the back)
are of equal width. For a faster way to make Rabbeted drawers see
the QUICK RABBETED DRAWERS section.
The width of the rabbeted drawer front, measured between
rabbets, should equal the width of the drawer sides and back. The
length of the rabbeted drawer front, measured between rabbets,
should equal the length of the drawer back. See pg. 10.
A rabbeted drawer front and its adjoining sides must be cut
in separate operations, unlike the parts for a Standard drawer. The
remaining sides and back parts are cut like a Standard drawer, in
pairs. A Rabbeted drawer will require six setups, one setup (x 2)
for each rear drawer corner and two setups (x 2) for each front
drawer corner.
Rout the mating dovetails into the two front ends of the
adjoining drawer sides. Clamp a piece of scrap where the drawer
front usually goes, against the drawer side, to prevent tear out.
The rabbet in the drawer front should be at least 5/16" deep
to clear the dovetail bit. The end of the drawer should be indexed
so the shoulder of the rabbet is aligned with the front of the Ultra
Track. You’ll need to make an indexing block to position the
drawer front correctly. Cut a piece of scrap with the same width
rabbet as the drawer front and clamp it in the front of the dovetail
jig where the side would normally go. Slide the drawer front forward to index its front edge against the rabbeted lip in the indexing
block and tighten the top clamps. See fig. 21A. Rout both ends of
the rabbeted drawer front this way.

1/4” Stop Setting
1/4” Stop Setting
The bottom edge of rabbeted drawer front must be indexed
against the stop pin, with an additional spacer placed between the
rabbeted edge and the stop pin to offset it correctly. For example,
if you have a 3/8" wide rabbet and you’re using the standard 7/16"
dovetail template, you’ll need a 7/8" wide spacer. See fig. 21B.
QUICK RABBETED DRAWERS
Instead of making a Rabbeted drawer, make a Standard
drawer with the drawer front made of the same wood species as
the desired rabbeted drawer would be. After assembling the drawer
glue a larger drawer front to the standard drawer front. This provides the same appearance as a one-piece rabbeted drawer, but is
quicker and easier to make.
