Cut the pieces for the drawer boxes. Drill pocket holes in each end of the sides as well as all four edges of the bottom. Assemble as shown using glue and 1-1/4” pocket hole screws. Install the drawer slides according to the manufacturer’s instructions then make any necessary adjustments.
Cut the pieces for the drawer fronts noting that the bottom drawer front is taller. There will be an 1/8” gap around all sides of the drawer front. Place the drawer front in the opening and shim in place. Drive screws through the holes for the handles to temporarily hold the front in place. Open the drawer and attach the front to the drawer box from the inside with 1-1/4” screws. Finish drilling out the holes for the handles.
