Veneering Wide Panels

Veneering wide panels is easy with a simple shop-made press. All you need are some scraps of oak, a few sheets of kraft paper

and ordinary particleboard.

Most woodworkers who start experimenting with veneer quickly face a dilemma. They need to cover a surface wider than the capacities of their clamps but they don't want to purchase a costly veneer press. Don't fret; try caul veneering. It's cheap, easy, effective and adaptable to most of the situations you'll come across.

Caul veneering is a simple idea consisting of two easy-to-make wood devices known as cauls and crossbearers. Cauls are pieces of 3/4" particleboard cut slightly larger than the core that's being veneered. Crossbearers are long pieces of hardwood with a slight arc cut on one side. When used together these devices transfer clamping pressure to the center of

Figure 1: To form the arc, clamp a thin wood strip to the center of an oak crossbearer and bend the strip so it is 1/4" from the edge at the ends of the board. When the crossbearers are clamped onto the cauls they distribute pressure over the entire width of the veneer evenly.

the core, across the veneer, and then out to the edges (see Figure 1). This technique eliminates the chance of trapping glue pockets between the veneer and its core.

Preparing the Veneer and Core

The first step in veneering is to splice and join your veneer sheets together and cut the particleboard core to its finished dimensions.
