These easy-to-make shop aids really simplify edge-gluing boards. The clamp blocks spread each clamp's pressure over a wider area and feature hardboard "outriggers" that keep the blocks in place while you position the clamps. They also prevent the clamp's pipe or bar from touching the panel's surface and creating a glue stain on your project.

The blocks without outriggers, called alignment blocks, bridge across the faces of mating boards, keeping their surfaces flush during assembly and as the glue dries. Cutouts prevent you from accidentally gluing the blocks to your workpieces.

To make a set of blocks, start by cutting a 2 12 "-wide blank from 34 "-thick stock where shown at top. Make the blank as long as you wish, working in multiples of 418 " (final trim size of 4"). Next, lay out and drill a series of 1" holes through the blank, centered on its width, where dimensioned on the drawing. Now rip and crosscut the blank as dimensioned.

Cut a pair of 12 " bevels on each block using a bandsaw. For now, set aside the pairs you plan to use as alignment blocks. Complete the clamping blocks by adding 14 " hardboard outriggers.

Add a couple of coats of clear finish to all the blocks to prevent glue from sticking to them. Finally, apply 34 " self-adhesive cork pads (available in hardware stores) to the edges of the clamping blocks to prevent workpiece-marring.
