Dovetails are one of the most popular and often made joints in woodworking, and this sled is designed to make cutting them as simple as possible. If you like the look of hand-cut dovetails, but don’t have time (or patience) for all the meticulous work it takes to create them, then try this table saw method which uses a sliding dovetail sled to cut 90 percent of each joint.
With care and a bit of practice, you can produce large or medium sized, “furniture grade” 8° dovetails in both hard and soft woods. You can make the dovetail sled from either MDF or a high quality plywood, such as Baltic birch.
Figure 1: Once you've had the triangular braces cut at 45°, attach them to the inside piece of the pin fence, then glue them up to the baseplate. Figure 2: Nail down the 8° wedge ramp to the base of the sled, but don't put any nails into the middle section where the saw blade will pass through. Figure 3: Attach braces to the tail fence to keep it perpendicular to the base, then set the glue-up to cure overnight.
Butt the tail fence (piece 5) up to the inside of the ramps and fasten it in place, using three more triangular braces to keep it perpendicular to the base, as shown in Figure 3.
Figure 4: Attach the miter bar to the bottom of the jig with with short washerhead, to help guide the sled.
To guide the jig, I fastened an adjustable miter bar (piece 6) to the underside of the jig’s base with short washerhead screws, as shown in Figure 4. Figure 5: To create the locations for your dovetails, make four registration slots in the jig's fence, glue in some blocks to cover the blade exit and protect your hands.
With a regular, not thin-kerf, blade fitted, start the saw and carefully “cut in” a registration slot on the pin fence as shown in Figure 5 on the following page. Figure 6: These markings are exaggerated for display, but mark out the narrow sides of the pins on the outside face of the boards and the waste areas (Xs here). To use the jig, start by marking out the width and spacing of the dovetail pins on the outside-facing side of all your project’s pin boards (label the outside face, to help you orient the board for cutting later). Figure 7: Using your sled, begin by making the right side cuts on each pin of the dovetails.


Figure 8: To remove the waste from the sides of your dovetail pins, make multiple passes with your sled over the table saw. When all the righthand cuts are done, move the jig to the saw’s left-hand slot and repeat the process, this time cutting on the waste side of the left-hand edge of each pin. Figure 9: Use your pin board and a square to mark the placement and depth at which you will cut your dovetail tails.
Once pin boards are cut, use the pins themselves to transfer the dovetail layout to the inside face of each corresponding tail board (Figure 9). Figure 10: Spin the jig around to cut the dovetail tails, using the ramps to make the left and right hand cuts. Now flip the jig around front to back and use the tail-cutting ramps to saw out the tails (Figure 10).
Step 11: Using a narrow bandsaw blade, cut away the waste between the tails, setting the fence away at a proper distance. Rather than chopping out the waste between tails by hand, it’s quicker and neater to saw the waste out using a band saw (or scrollsaw). I'd like to get the plans for this jig if they are available and the adjustable guide bar for the miter slot. For those that are looking for plans, look at the beginning of the article where it says, Dovetail Sled's Diagram and Materials List, click here to download the PDF.
The jig cuts dovetails far faster than you can cut them by hand, and you can size the pins and tails and customize their spacing to suit just about any project — join drawer sides, build a box or small chest, etc. However, I think the jig is best for quickly cutting workmanlike joints that are serviceable for jobs like joining parts for tool chests and totes, drawers for kitchen or shop cabinets, and so on. Glue each pair together to form the wide ramps (pieces 4) that will support the tail boards at an 8° angle. Center the bar and use a large try square or framing square to set it dead square to the base’s long edges.
Move the bar to the other miter slot and cut in the second slot, then flip the sled around and cut in both registration slots on the tail fence side. Hold the stock firmly against the left-hand pin fence, with the pin board’s inside face against the fence.


As shown, this jig is capable of handling stock up to about 12" wide (you can build a jig to handle larger work: simply increase all dimensions proportionally to build a bigger jig — just keep all the angles the same).
Glue and nail two triangular braces (pieces 3), cut at 45°, to the inside face of each pin fence, then attach them to the baseplate, as shown in Figure 1. Glue and nail each ramp flush with the long edge of the base, as shown in Figure 2 (don’t drive nails in the area around the middle section of the ramps, where the table saw blade passes during use). Set the finished sled’s bar into one of your table saw’s miter slots and adjust the bar so it’s free of side play, yet slides smoothly. To make the jig safer to use, glue square 2x4 exit blocks (pieces 7) to the base at the back of each slot, directly over the saw kerfs you just cut. Figure 6 shows the angle of the pins in red for illustration; no need to mark pin angles on your boards, since those are set by the fence angles. Use the left- and right-hand ramps to cut along the right- and left-hand tail marks just as you did with the pins, moving the jig from one miter slot to the other as necessary.
To keep the jig from sliding beyond the point where the saw blade passes through the exit blocks, clamp a stop block into both of the saw’s miter slots. Now cut on the waste side of each mark that delineates the right-hand edge of the pin (Figure 7).
Hold the outside face of each tailboard against the fence and make sure to cut on the waste side of each line.
Between the height of the base board, the height of the ramps, and then the height of the cuts needed in the actual stock, I didn't have enough blade height to cut the actual dove tails.
Use a square to draw a line across the end of each pin board to indicate pin depth — just a thin hair deeper than the thickness of the tailboards.
