Clean the reclaimed wood of debris, remove any jutting splinters or exposed nails, and then clamp it into an adjustable workbench. Use a vice or clamps to sturdy the wood if you do not have an adjustable workbench.
Cut a piece of wood from the original beam using a circular saw. The project pictured was made with two wood blocks, each measuring 8 by 4 by 3 inches. A circular saw or table saw can be used to make the initial cuts.
Use the first cut piece of wood as a template to measure and cut an equal-sized second block.
Sand both wood blocks using 80-grit sandpaper to smooth any rough edges. A palm sander makes sanding a quicker process and achieves an overall even finish.
Adjust the circular saw to a 45-degree cutting angle; this creates the faceted sides of the geometric bookends.
Secure one of the wood blocks to the workbench. Choose a spot on the block edge about halfway down, and make a 45-degree cut straight through to the top of the wood block, removing a corner. The result will look like a triangle.
Repeat the same cut, working your way around the wood block to make faceted sides by removing the corners. To create the irregular, natural facet shapes in the completed piece, leave at least one corner in its original form, and choose different points along the wood block’s edge before making each angled cut.
Repeat this cutting process with the remaining block of wood, and then sand both blocks to smooth any rough edges.
In a well-ventilated area, brush a clear coat of wood sealer to cover each wood block. This provides a protective coating and keeps the natural-looking finish. For a different look, finish them with your choice of wood stain, paint or finishing oil.
Allow the finish to completely dry, as per the finish product's directions, in a well-ventilated area before bringing the bookends into your space.
Use the bookends alongside your favorite books or mix them into your decor for a rustic feel.
