Photo 3- Join the drawer frames with groove and tenon joints cut at the table saw, then glue them up as shown. Install drawer guides in the front and rear pieces.

Construct drawer frames using a tenon and groove joint, with ½" deep grooves in the drawer frame rails and ½" tenons on the ends of the drawer frame runners. Such tenons can easily be made with a table saw tenoning jig such as that shown in the Benchtop Router Table project on this site. Fit drawer guides into the frames as shown in photo 3. You only have four mortises to cut for the guides, so cut these by hand with a chisel. Once the drawer frames are assembled, bore them at their corners for the dowels that join them to the posts as shown in photo 4.

Photo 4- After the drawer frames are out of clamps, bore for the dowels that will join them to the vertical posts in the side frames.

Dry clamp together the side frames with the front and rear rails, but not the drawer frames, using 1/2" long dowels to locate the parts. Cut a 1/4" deep by 3/8" wide rabbet along the inside rear edge of the rear bottom rails, mid rails and posts with a router and bearing guided rabbeting bit. This rabbet is for the plywood back. Chisel the corners square.

Photo 5- Glue together the carcass with a large number of clamps as shown. Check for square on the top and bottom as well as front and back.

Glue together the carcass as in photo 5. Check for square in the front and back, as well as top and bottom. Glue and screw in place 12 corner blocks where the carcass rails join the posts on the top, bottom and middle.
