Use pocket-hole joinery to attach the pantry's side panels to the top and bottom panels. This method uses screws and pre-drilled holes bored into the wood at a very steep angle, almost parallel to the surface of the wood. We are using a purchased kit that supplies several tools to facilitate the process. Begin by attaching the special step drill bit, with its pilot end and adjustable stop-collar, to your power drill. Adjust the stop-collar to control how deeply the bit will penetrate the wood.

Set the wood panel on its edge in the jig that clamps and holds it in a vertical position while you insert the drill into the drilling jig that holds the bit at an angle. These kits are available from your home-improvement store. Pre-drill the required holes at the locations marked on the panels.

Apply glue to the edges and butt the edges together.

Use a joining clamp to hold the corners in position. You can use a specially designed pocket-hole clamp to pull and hold the pieces tightly together. One end of the clamp actually fits into one of the pockets that you have just drilled, while the other end presses flat against the other panel's surface.

Once everything has been glued and clamped together, drive in the screws.
