To do that, both the joinery and each part of the stand contribute to its overall strength. Solid Base. In the drawings at right and on the opposite page, you can see how the base Is built. It's made up of three separate assemblies — two ends and the drawer. The ends are built first and connected by stretchers. Building a base like this requires solid parts.
