JIGS & ACCESSORIES ^^ platforms. With the base complete, you can turn your attention to the two platforms. Besides raising the door off the base, the platforms support a system of cleats that keep the frame square. Both platforms are made from the remaining piece of the blank used for the base. But before cutting it into two pieces, it's best to attach the cleats to ensure that they will align with each other. cleats. The cleats start out as a long blank that's made by gluing and screwing two strips of 3/4m MDF together, see Fig. 2. To help keep the door flat against the base, one edge of the blank is beveled, see Fig. 2a. Then the long (B) and short cleat (C) are simply cut to length. Before attaching the cleats, there's one more thing to do. That's to bevel the end of the short cleat so it fits against the edge of •the long cleat, see Figs. 2b and 3. attach cleats. Now you can attach the cleats. The important thing here is that the corner formed by the cleats is square. This way, the door that's glued up will be perfectly square too. After gluing and screwing the cleats in place, you can rip the blank into two pieces: a narrow fixed platform (D), and a wide adjustable platform (E), see Fig. 4. runners. To complete the adjustable platform, you'll need to add the two runners (F), see drawing on opposite page. These are nothing more than strips of MDF that are cut to fit the dadoes in the adjustable platform. attach fixed platform. All that's left is to attach the fixed platform to the base. This plat form has a small lip that overhangs the groove in the base, see detail 'a' in drawing on page 28. Later, this lip traps the mounting blocks for the cams in the groove. To form this lip, simply rabbet the bottom edge of the fixed platform (D), then screw it in place.
