I The Dado The first step in making the joint is routing a dado across each end of the drawer sides. It will accept a tongue that will be routed on the ends of the drawer front and back. In setting up for an accurate cut, I try to do as little measuring as possible. Instead, I use the work-pieces themselves as setup gauges. You can see what I'm talking about in the left drawing. Here, I use one of the front or back pieces to position the router fence. The outside face of the front should align with the outside cutting edge of the bit. The only measuring I do is to set the bit height (right drawing). backerboard MOTE: use a backerboard to prevent tearout and keep workpiece square to fence/ THE CUT THE SETUP set bit height to'a" 2 The Rabbet outside edge of bit should align with thickness of workpiece ^ straightedge 1___, drawer front/ back align inside cutting edge with fence face The mating half of the joint is a tongue that's made by cutting a rabbet on each end of the drawer front and back. The goal of this step is to end up with a tongue that fits snugly in the dado in the side. Like routing tine dado, I use the workpieces to set Lip for the cut. In the "setup" drawing at left, you can see how I use the dado in the side pieces to set the bit height. As for setting the fence, all you need to do here is position it so the face is flush with the inside cutting edge of the router bit. As always, make a test cut to check tine setting. 3 The Groove That takes care of the joinery, but there's still one step left. And that's a groove in the drawer front, back, and sides to hold the drawer bottom. I like to cut this groove about y4" up from tine bottom edge. If you plan on using Vi" plywood for the drawer bottom, tine fit maybe a little loose. For a snug fit, you can do this on the table saw and make a couple passes with a standard blade to sneak up on the fit. ^L NOTE: rout groove on inside face of all drawer parts position groove 'a" from edge , NOTE: backerboard not needed to rout groove with grain set bit height to '/*" 27 |
