Recess to clear screw head spring-loaded pin at the top of the arm to hold the arm in the locked position (see the drawing above left). When you pull back this pin (which can, of course, be accessed only from inside the box), a spring set at the bottom of the arm forces it back up, drawing the screws out of their locking plates.

The drawing above right illustrates the "card-lock" system that Nels designed to secure the lids to the box. To unlock the lid, you slip a credit card between the top drawer and the end board, sliding it to the left until it hits the brass bar. As you exert a little pressure, the bar pivots and releases the lock pin attached to the inside of the right-hand lid (see the drawing above right). Note that the left-hand lid is captured shut by the lip board. Because of the return spring, this catch automatically locks itself when you shut the right-hand lid. All this action, and not a microchip in sight!

To make the catch, cut a piece of '/ยป-in. thick by 5/s-in. wide bar stock long enough to span between the top of the upper drawer and about 1V\ in. up the side of the coopered lid. Cut and file a curve (to guide the lock pin during the closing motion) and a notch (to enclose the lock pin) in the upper end of the bar.

Then drill holes for the pivot screw and the return spring. Install the catch to the back side of the end board, orienting the bar so it just protrudes into the gap between the drawer face and the board. Mark the location of the lock pin on the inside of the lid through the notch in the bar. Install this pin, and then attach the spring. Create just enough spring tension to hold the bar tight against the lock pin. Test the catch. Trim the notch and the curve with a fine file if necessary to ensure a smooth, positive locking action.

Making the carry handles

To make the end-mounted carry handles, start with a long length of stock sized in width and thickness, then use a shaper cutter to create the outside profile. Cut the finger notch with another cutter. If you don't have 3 shaper, you can rough out both the finger grip undercut and the outside profile on a table saw. Mere's how:

Do the undercut first (see the drawing at right). Mark the outline of the notch on two faces of the stock. Then, holding the wood against the miter gauge, run it into the sawblade at the centerline of the notch. Adjust the blade height so that the kerf meets both outlines. Then cut kerfs to either side of the center kerf, being careful to stop the cuts at the outline mark. Do not knock out the waste yet. Instead, set up the saw-to cut kerfs in the waste area of the outside profile. Adjust the height of the blade and the rip fence to produce a series of kerfs as shown in the drawing.

With the kerfs cut, remove the waste from both the outside profile and the undercut with a chisel. Smooth the undercut finger grip with the nose of a belt sander. Use the flat of the sander to smooth the outside profile. Finally, cut the handles to length from the shaped stock and again use the nose of the belt sander to form the curved end profiles. Install the handle to the box with screws from the inside of the end boards.

Finally, apply the finish of your choice to all the wood surfaces, inside and out. Install the tilt-out trays and fit out the box with your tools. Then tell your coworkers they are going to have to find another place to sit at lunch time.
