2 Punch a smaii starter hole at the centerpoint of each pin hoie. if your project is a manageable size, use your driii press to drtii the hoies, as we did In the photo above. Using a brad-point bit will ensure that the hoie starts precisely in the centerpoint. Drili the holes aii the way through the tenon and into the other side of the mortise. Use a bit stop if your pian caiis for stopped pins, if you're creating through-pin joints, drili ali the way through the joint and into a piece of scrap.

4Trim the doweis fiush with the ieg surface-here we use a flexible, fine tooth Japanese-style saw. Depending upon the amount of dowei you need to remove, you may be able to smooth the ends flush with a file instead of sawing them off.

3Cut the pins from hardwood doweis, normaiiy of the same species as the workpieces. Tip: For a decorative touch, use doweis made of wood with a naturally contrasting wood tone (for exampie, mapie pins driven into walnut workpieces). Taper the iead tip of the dowei slightly so It will enter the hoie more easily. Squeeze a little glue into each hoie, then tap the dowei pins home with a wood maiiet. Stop tapping when the dowei seats at the bottom of the hoie.

Lap joints

Lap joints combine the interlocking characteristics of rabbets and dadoes in a number of different configurat ions to join tw o boards face to face. Lap joints are a better alternative to butt joints for frame construction, because laps offer much more gluing area and the pieces actually interlock mechanically. Usually, the thickness of both parts of a lap joint are equal, and the pieces fit together so that both faces of each joint pari line up with one another. In order to do this, the overlapping dadoes or rabbet tongues are as large as the mating piece is wide.

Three of the more common lap joint types are the corner half lap, aT' half lap and cross lap. Corner half laps consist of two wide rabbets cut across the faces of two workpieces at the ends. The cheek portion of each rabbet matches the width of the opposite workpiece. "T" half laps fasten the end of one board with a wide rabbet to the midsection of another board that's fitted with a matching dado. Cross laps are half-lap joints where both members are dadoed and the joint is not- at the end of either part. All three types are made by cutting a wide dado into each joint member—either on the face or edge—then interlocking the dadoes.

Cutting lap joints. Aside from their larger size, the rabbets and dadoes that form lap joints are cut just like any other rabbet or dado. Whatever blade you choose, you'll need to mfike multiple passes to cut these rabbets and dadoes. For most efficient cutting, it makes sense to use a dado blade so you can remove more material with each pass. A dado blade is also the right choice for long or unwieldy workpieces. In these instances, cut the rabbets or dadoes in multiple passes with the workpiece lying facedown on the saw table.
