ISet the cutting width of your dado blade fay adding chippers and spacers between the two blades. Mount the set on your table saw arbor. When mounted In a table saw, dado-blade sets require a saw throat plate wfttr an extra-wide opening.

2Set the cutting height to the desired dado depth, then adjust the fence so the blade set will start cutting at the shoulder of the planned dado. Make a test cut first, feeding the stock through the blade slowly, with plenty of downward pressure. Use a push block when you near the blade. Measure the dado on the scrap and adjust your setup as needed. In harder stock, It's a good Idea to make the cut in multiple passes of Increasing cutting depth.

WITH A DADO BLADE SET. A dado blade (See photo, top left) can cut shallow rabbets in a single pass. If the rabbet is deeper than % in. or the wurkpiece Is hardwood, make the cut In multiple passes. Attach a sacrificial wood fence to the rip fence. Set the fence position and cutting depth, then make the cut. Use a hold-down, featherboard and pushstick to guide the workplece.

WITH A STANDARD BLADE Cutting rabbets with a standard-kerf saw blade involves cutting the cheeks with one saw set up, then trimming the shoulders in a second operation. When cutting, be sure that the waste piece Is on the sMe of the Made opposite the fence and use a zero-clearance throat plate. To make the cheek cut, stand the workplece en-edge or on-end against the rip fence. Install a tall auxiliary fence for rabbeting the edges of wide workpleces. Set the distance from the rip fence to the blade so the blade rats right at the cheek cutting line. Set the blade height so the teeth just touch the shoulder layout fine. Make the cut (top photo). Adjust the saw setup and make the shoulder cut (bottom photo), using a push block to hold down and feed the workplece.

TONGUE-AND-G ROOVE JOINTS are fashioned by cutting a centered tongue In the edge or end of one board that fits into a centered dado or groove on the mating workplece. By centering the tongue and fitting it into a centered dado or groove, the shoulders on the tongue side of the joint completely hide the slot made by the dado or groove-a real advantage for concealing the slot-side of the joint.

Tongue & groove joints

Tongue-and-groove joints are a strong, easy-to-build alternative to butt or rabbet-and-dado joints. These centered-tongue joints find their way into a variety of different panel and carcase applications. Tongue-and-groove joints are often used to form cabinet back panels, and the pieces are assembled without glue. They are also useful for aligning boards when edge-gluing a panel. Cutting tongue-and-groove joints is a three-step process. You'll first cut the groove or dado along the edge, end or face of one workpiece, then make two identical rabbets along the edge or end of the mating work-piece to form the tongue. It doesn't matter whether you cut the slot first and then the tongue or the other way around.

Cutting dovetail joints by hand

The hand-tut dovetail joint is perhaps the most famous, and intimidating, woodworking joint. As with any other woodworking skill, mastering them is mostly a matter of practice. But with these joints,, visualization also helps. For many first-timers, the biggest hurdle to get past is simply studying the way dovetail joints fit together until they make sense.

Dovetail joints require a fair amount of planning and a good layout drawing. As you lay out the joint, keep a few basic principles in mind: The dovetail joint has two parts: the pin and the tail— always begin making dovetails by cutting the pins first. For joint strength and integrity, the joint should begin and end with a half-pin. The angle of the pin should not be steeper than 80" (a lifi ratio of slope to pin depth). The pin-and-tail spficing doesn't need to be exact: the tails can be up to three times as wide as the pins. In fact, the pin and tail sizes can even vary within a joint, which creates an interesting look that's unique to hand-cut dovetails.
