Planning a Bookmatched Live Edge Top

What Defines a Bookmatched Live Edge Pair?

A true bookmatch is created when a single log is sawn into two consecutive slabs, which are then opened up like a book. This process results in two slabs with nearly identical grain patterns that mirror each other along a central seam. The live edges, too, will often present a similar, though not perfectly symmetrical, curve.

It is important to confirm that the slabs you are considering were indeed cut as a matched pair from the same log. Slabs from different logs, even of the same species, will not offer the same mirroring effect crucial for a bookmatch. The visual impact of a bookmatched top comes from this natural symmetry, highlighting the wood's unique figure.

Verifying the Match and Usable Dimensions

When planning a bookmatched top, the first step is to verify the actual match of the slabs. Request current photos of the two slabs laid out together, opened as they would appear in the final project. This allows you to visually inspect the grain continuity, the consistency of the live edges, and any natural features like knots or checks that might align or diverge.

Beyond the aesthetic match, confirm the minimum and maximum width of each slab, as well as its length and thickness. The usable width of your bookmatched top will be the sum of the usable widths of each slab, minus any material removed for joining. The live edges will define the outer contours, so consider how their natural curves will integrate into your design. For example, if one slab has a significantly wider point than the other, this will create an uneven profile when joined, which may be desirable or require adjustment.

Pay close attention to any existing checks, voids, or inclusions in each slab. While these are inherent to live edge material, their placement and size can become more prominent when mirrored. Discuss with your fabricator how these features will be addressed, whether through stabilization, filling, or strategic placement within the design.

Planning for the Center Seam and Joining

The seam where the two slabs meet is a defining characteristic of a bookmatched top. This seam can be straight or follow a natural curve, depending on the milling and your design preference. A well-executed seam should be tight and visually consistent.

The method of joining the two slabs is critical for stability and appearance. Common methods include biscuit joints, dowels, or splines, combined with a strong wood adhesive. For larger or heavily used tops, additional reinforcement such as steel flattening bars or C-channels routed into the underside may be considered to help maintain flatness over time. Always consult with your woodworker or fabricator on the best joining method for your specific project and the wood species chosen.

A Hypothetical Example: Bookmatched Dining Table

Consider a hypothetical project for a dining table measuring 96 inches long by 40 inches wide. You identify a bookmatched pair of Maximo Cumaru slabs, each listed at 98 inches long, with a minimum width of 20 inches and a maximum width of 24 inches, and a thickness of 2 inches. After reviewing current photos, you see that the live edges are relatively straight, making them suitable for a dining surface.

When laid out side-by-side for a bookmatch, the combined width at the narrowest point would be 40 inches (20 inches + 20 inches). At the widest point, it would be 48 inches (24 inches + 24 inches). This provides flexibility to achieve your desired 40-inch width while allowing for some shaping of the live edges. The extra 2 inches in length (98-inch slabs for a 96-inch table) provides room for end trimming and squaring.

In this scenario, the usable dimensions align well with the project requirements. However, if the slabs had a minimum combined width of only 36 inches, you would need to adjust your design or select a different pair to meet the 40-inch target width.

Considering Wood Movement and Slab Stability

All wood responds to changes in humidity by expanding and contracting. This is particularly important for wide, joined tops like a bookmatch. Ensure that the slabs have been properly dried and have a stable moisture content appropriate for your climate and intended indoor environment. Information on moisture content should be available for the specific slabs.

Even with proper drying, some movement can occur. Design considerations, such as attaching the top to a base using methods that allow for seasonal movement (e.g., slotted fasteners), are crucial to prevent cracking or warping. Discuss these details with your fabricator to ensure the long-term stability of your bookmatched top.

Selecting Your Species and Finish

The wood species you choose will significantly influence the appearance and characteristics of your bookmatched top. Different species offer varying grain patterns, colors, and densities. Maximo Cumaru, for instance, is known for its rich color and dense grain, which can create a striking bookmatched pattern.

The chosen finish will also play a role in enhancing or subtly altering the appearance of the bookmatched grain. A clear, natural finish will allow the wood's inherent beauty to shine through, emphasizing the mirrored patterns. Other finishes, such as those with a slight tint or matte appearance, can also be considered based on your aesthetic preference. Always consider how the finish will interact with the wood's natural color and grain.

Before you order

• Have I confirmed that the slabs are a true bookmatched pair from the same log?
• Have I reviewed current photos of the slabs laid out together to assess the grain match and live edge consistency?
• Do the combined minimum and maximum widths of the slabs meet or exceed my project's desired dimensions?
• Is the length of the slabs sufficient for my project, allowing for trimming?
• Have I considered how existing checks, voids, or knots will appear when mirrored and discussed solutions with a fabricator?
• Have I discussed the joining method for the center seam with my fabricator?
• Is information on the slabs' moisture content available and suitable for my project environment?
• Have I planned for wood movement in the design and attachment to the base?
• Does the chosen wood species and intended finish align with my aesthetic and functional goals?

Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
