Woodworking: plan and build small projects

A benchtop box must fit its location, hold the intended objects and sit flat. Three questions guide its design: how much space is available, what goes inside and how do the parts support each other? Make a cardboard volume first to try the footprint. A large outside size can still leave little useful room inside.

This course uses an open 300 × 200 × 120 mm organiser for small objects in a dry indoor setting. Five plywood parts form the base and walls; four short solid-wood posts reinforce the inside corners. The walls stand on the base. Short end walls fit between the long walls. This arrangement explains why the parts do not all use the outside dimensions.

You may order precut parts and focus on checking, gluing and finishing. Owning a saw is not required to understand the project. Support the base when moving the organiser; the edges are not handles. A stool, suspended shelf or children's furniture requires different sizing and joints: enlarging this box does not establish a load capacity.

Solid wood retains continuous tree fibres. Plywood bonds veneers with alternating grain directions; this reduces in-plane movement compared with a comparable solid board, but does not eliminate moisture effects, voids or warping. MDF combines fibres and resin into a uniform face; its edges and response to water and fasteners differ from plywood.

For this project, select flat, uncoated plywood without delamination, with faces suitable for your intended finish. Inspect the edges too: a void directly on a joint line reduces available contact. An attractive face does not repair a defective core. Corner posts should be dry, straight, square-section stock without loose knots in the bonding areas.

A clear finish leaves veneers and defects visible; opaque paint conceals colour but not a loose edge. Do not automatically substitute melamine-faced board: its coating changes adhesion. Ask the supplier to identify the panel and its intended use. Exterior plywood combined with interior assembly glue does not make the box suitable for rain.
