OPERATION
MISCELLANEOUS TECHNIQUES
Using these techniques can simplify your dovetailing projects.
USE A DEAD-BLOW HAMMER
Use a plastic dead-blow hammer to join your workpieces together to help prevent the marring of wood (Fig. 1A).
CHAMFER THE TAIL EDGES
Chamfering the inner tail edges can make the joints go together easier and may prevent damage to the pins (Fig. 1B). Make the chamfers with a file or a chisel. Since the chamfers are located on the inside of the joint, they will be invisible.
This method of setting your router bit depth on through dovetails or box joints is very accurate for creating pins or tails that are flush, and is especially good for inlay work. Use a board that is the same thickness as your workpiece to be joined and draw a line.
ALTERNATE THROUGH DOVETAIL AND BOX JOINT BIT DEPTH SETTING
Set the router on the template and lower the router bit until it reaches the line. Make sure that the scrap material used in the horizontal position to support the template is at least as thick as the router bit depth-of-cut.

THROUGH-DOVETAILS WITH CLAMPING BOARDS
You can use both the normal through-dovetail template (included with the 4212 Jig and the 4213 Accessory Kit), and the miniature through-dovetail template (included with the 4215 Accessory Kit) with a clamping board.
NOTE: You can modify these clamping board methods to make box joints.
SETUP
Step 1 -
Step 2 -
Make a clamping board 2" x 3" x 19". Make sure that all four sides are square (You may need to glue thinner sections of wood together and plane them to make the 2" board).
Drill the pilot holes for #10 screws on the face of the board as indicated in the drawing (Fig. 6A).
Remove the brackets from the template (Fig. 6B).
Align the lines of the template with the edges of the clamping board. You should be able to see the pilot holes in the elongated slot of the template Fig. 6C).
Drive two #10 wood screws through the elongated slots of the template into the clamping board (Fig. 6D).
TEMPLATES MOUNTED TO CLAMPING BOARDS
You can mount the jig templates to clamping boards and take the templates to the workpiece to make the joint. The benefits of this operation are:
1. You can maneuver a mounted template onto a large workpiece easier than clamping a large workpiece to the jig. This process allows you to join boards wider than 12" by routing a part of the joint, sliding the mounted template just past the original cut, and routing the remainder of the joint.
2. By using the clamping boards, you can rout boards that are too short to clamp in the jig base, allowing you to dovetail small decorative boxes.
3. You can make half-blind joints in thicker wood than the jig can handle.
4. You can make steeply-angled joints with the clamping boards.
5. You can make joints using a router table by inverting the mounted templates.

Step 2 -
Clamp the tail board with the outside surface facing away from the clamping board (Fig. 7A). Align the tail board, using the instructions in your basic manual in the section “OPERATION”. Look under “POSITIONING THE WOOD”, STEP 4.
This step is optional. Clamp stop blocks to the clamping board for rapid setups of repeated cuts. Use a small square and a pencil to draw a line along the bottom of the clamping board (Fig. 7B). Align the
line with an edge of the tail board. (This line will be used to set up the pin board). Use the width of the pinboard to mark the depth of the router bit on the tailboard (Fig. 7C).
DISCONNECT THE TOOL FROM THE POWER SOURCE.
Set the router bit depth, using the pencil mark from STEP 4. Connect your router to the power source and cut the tails (Fig. 7D).

THROUGH-DOVETAILS WITH UNLIMITED BOARD WIDTH
You can cut dovetails in boards wider than the templates mounted on clamping boards by cutting the first part of the joint, sliding the templet down the workpiece, and cutting the rest of the joint.
NOTE: Become familiar with the procedure for cutting through-dovetails with a template on a clamping board before attempting working with unlimited board width.
SETUP
Remove the half-blind depth bracket. Other than that, the setup is identical to the previous setup.

Fig. 10D
Clamp the tail board with the outside surface facing away from the clamping board (Fig. 10A). If the board is a width in 1" increments, (12", 13", etc.), center the edge of the board exactly between the
two fingers of the template farthest to the left (Fig. 10B). If the board is not in 1" increments, take the fraction of an inch that is greater than 1" and divide it by two.
Then move the tailboard to the left of the center of the fingers by that amount (Fig. 10C). EXAMPLE: IF the board width is 16-1/2", take the 1/2", divide it by two. You would then move the tail board to the left of the center of the fingers by 1/4" and clamp it in place.
Use a piece of wood the same thickness as the pin board to mark the router bit depth.
DISCONNECT THE TOOL FROM THE POWER SOURCE.
Set the router bit depth, using the pencil mark from STEP 4.
Connect your router to the power source and cut the pins as far as the template will allow.
Unclamp the templet, slide it down, and center the last cut between the two straight fingers and reclamp (Fig. 10D).
Repeat STEPS 6 and 7 until the pins are cut across the entire board.
Clamp the pin board with the outside surface facing away from the clamping board. If the board is a width in 1" increments, (12", 13", etc.), center the edge of the board exactly in line with the
finger of the template farthest to the left (Fig. 11A). If the board is not in 1" increments, take the fraction of an inch that is greater than 1" and divide it by two.
Then move the pin board to the left of center of the fingers by that amount. EXAMPLE: IF the board width is 16-1/2", take the 1/2", divide it by two. You would then move the tail board to the left of the leftmost finger by 1/4" and clamp it in place (Fig. 11B).
Use a piece of wood the same thickness as the pin board to mark the router bit depth.

HALF-BLIND DOVETAILS WITH CLAMPING BOARDS
You can mount your half-blind template that comes with the 4210 and 4212 jigs and the 4211 accessory kit to a board. This method, however, limits your workpiece width capacity to 8".
SETUP
Items needed to setup for the half-blind dovetails:
1. Wood to make the clamping board parts
2. Clamps
3. 2" #10 wood screws (2)
4. 1/4-20 threaded T-nut
5. 1/4-20 x 4" bolt
6. 1/4" washer
NOTE: These instructions can be modified for making half­blind dovetails with the through dovetail template and for the miniature dovetail template (See the section “HALF-
BLIND DOVETAILS WITH TAIL BOARDS THICKER THAN 7/8").
Fig. 14A
Fig. 15A Fig. 15B
Make a main clamping board 1-1/2" x 3-1/4" x 16". Square all of the sides. Make a mortise through the board and drill pilot holes for #10 wood screws (Fig. 15A).
NOTE: Threaded inserts and #10 flathead machine screws can be used in place of the #10 wood screws.
Make the offset clamping block. Make a counterbore for the threaded T-nut (Fig. 15B). NOTE: If your pin board is thinner than 3/4", modify the dimension. You may need to use extra
washers to prevent the bolt from sticking out.

NOTE: You can cut the pin and tail board separately, if you prefer.
Slide the straight clamping block to the left so that it contacts the pin board (Fig. 16D). Hook the straight clamping block over the front and back of the main clamping board.
Secure the pin board by clamping it between the offset and straight clamping blocks (Fig. 16E). Loosen the #10 wood screws, align the template lines with the line where the pin board and tail board
meet, and retighten the #10 wood screws (Fig. 16F).
DISCONNECT THE TOOL FROM THE POWER SOURCE.
Set the router bit depth, using the bit depth guide.
Cut the joint. Fitting the joint is identical to a standard half-blind dovetail.
Use protective handles to keep your hands away from the router bit. Grip the handles only on the
opposite side of the workpiece.
USING A ROUTER TABLE
You can use board-mounted templates with your router table. However, the templates must be inverted. Similarly, invert all operations (setting the router bit, etc.).
Make the protective handles using the dimensions in the drawing (Fig. 17B). Round over the ends of the handles so that they are comfortable in your hands.

ALTERNATE ROUTER BITS
You are not limited to using the router bits supplied with your jig. Other router bits can be used to produce a different look or to work with thicker woods. Using alternate bits can help you produce more advanced joints (inlayed dovetails, etc.). Since 1/2" shank bits are stronger and are much less prone to deflection than the 1/4" shank bits, we recommend that you use the 1/2" shank bits with the 4210 and 4212 dovetail jigs, and with the 4211 and 4213 accessory kits.
THROUGH-DOVETAIL BITS
If you choose to purchase alternate through-dovetail bits, keep in mind the following:
1. The dovetail bit must have a 7° angle. This angle matches the tapered fingers used to guide the straight bit.
2. The sum of the diameters of the dovetail and straight bits must equal 15/16". For example, a 5/8" dovetail bit must have a 5/16" straight bit - the sum of both equalling 15/16".
3. The length of the cutter determines the maximum thickness of wood that can be cut. The length of the cutter on the dovetail bit is the maximum thickness of the pin board. The length of the cutter on the straight bit is the maximum thickness of the tail board. If your bits have 1" cutters, you can make through-dovetails with 1" thick boards.
4. Purchase bits that will not cut into the template guides. The template guide used with the dovetail bit has an inside diameter of 21/32". Use bits that will fit into this dimension. Some larger bits might work, but with minimal depth (Fig. 18A).
5. The inside diameter of the template guide used with the straight bit is 17/32". Use straight bits that are smaller than that dimension.
