In the woodworking universe, live-edge slabs have taken center stage. They pop up everywhere — for example, on coffee tables and floating shelves, as well as our live-edge wood phone cases, which are stunning, functional art pieces.
But as enchanting as these wood slabs are, they present unique challenges, especially if you're dipping your toes into woodworking for the first time. Let us walk you through working with live-edge slabs, including sourcing, preparation, working, and finishing.
What Is Live-Edge Wood?
Live-edge wood contrasts starkly with conventional lumber cuts. Rather than carving out straight, uniform shapes, live-edge cuts preserve the wood's original contours, featuring the bark and aspects of the tree's distinct formation. Characterized by a rugged charm, live-edge wood stimulates visual interest, offering a slice of nature's beauty in your living space.
The Unique Characteristics of Live-Edge Slabs
Different tree species have individual characteristics and appearances, making selecting live-edge slabs an essential part of the process. The size and shape also warrant your consideration. Before making a purchase, assess whether you can cut the slab to meet the dimension requirements of your DIY resin art project.
While looking for slabs free from significant defects or cracks is essential, minor imperfections could enhance the charm of your finished creation. Consider slabs with cracks and voids if you want a showstopper of an epoxy project. Epoxy resin fills wood flaws brilliantly, contrasting with the grains of the live-edge wood and producing a breathtaking effect.
Sourcing Live-Edge Wood
Selecting live-edge slabs involves considering the wood's species, size, and quality. The type of wood determines the color, durability, and patterns in your finished piece. From sturdy oak to elegant walnut, your choice of species can dramatically alter the look and feel of your live-edge piece.
A wider slab might be better if your goal is a coffee table. Alternatively, narrower pieces serve well for floating shelves or bench seats. Ensure the wood's internal moisture level is below 12% to prevent warping and finish issues. Kiln-dried slabs are preferable as they maintain stable moisture levels and eradicate bugs.
Prepare the Slab for Woodworking
Once you've selected the perfect live-edge slab, preparation is crucial to maintain its natural-edge beauty and showcase its unique grain. We've broken down this process into the most critical steps.
Clean & Sand the Wood
Take the first step toward prepping the slab by thoroughly cleaning the surface. This initial process involves removing any loose bark, dust, or dirt. After cleaning, it's time for sanding.
Sanding live-edge surfaces allows a smooth transition between the untouched natural contours and the worked surface. Remember that you can emphasize the wood's innate charm by retaining unique features like uneven grooves and raised edges rather than sanding the wood piece excessively.
Dry & Acclimatize the Wood to Prevent Warping
Properly drying live-edge slabs can stop splits from expanding further, but improper or rushed drying might cause undesired warping. Your slab must acclimate to the environment where you'll hang or keep the finished piece. This step ensures the wood's moisture content is in balance with its future surroundings, helping to stabilize the live-edge wood.
Assess & Treat Flaws
Not all imperfections require a fix when working with resin and wood. Deciding which flaws to fix or to celebrate as unique identifiers of the live-edge slab is a subjective decision each artisan makes. You can integrate these flaws into the finished piece, enhancing its character, whether it's knots, bug holes, or splits.
The distinctive character of live-edge wood comes from its bark. In most cases, if the bark is loose or partially detached, it's advisable to remove it. However, if the bark seems firmly attached, it might be a durable element that lends a unique, natural aesthetic to your live-edge project.
Consider Wood Movement & Joinery
Wood is an organic material that frequently shifts over time due to changes in temperature and humidity—a phenomenon known as wood movement. When planning the joinery, consider how the wood movement will impact your piece, particularly if you attach legs to live-edge tables or join live-edge slabs.
We recommend incorporating techniques in your plan to allow for natural wood movement, such as using modern hardware designed for this purpose or joinery designs that accommodate wood expansion and contraction. Implementing solid joinery techniques will help you maintain the slab's natural beauty while enhancing the structural integrity of your final project.
The Woodworking Process
Flatten & Shape Your Slab
The real woodworking fun begins once you've selected and prepped your live-edge wood. One of the initial steps involves flattening and shaping the slab to fit your project's requirements. Utilize wide-belt sanders or large gantry-style CNC routers with surfacing bits to flatten both sides of the slab. Proper support is crucial due to the weight of live-edge slabs.
Choose & Execute Joinery Techniques
Joinery is vital in live-edge woodworking. It offers the strength needed for weight-bearing structures like tables and benches. When joining live-edge slabs, make sure to pick a method that is both functional and aesthetically pleasing. Butterfly keys, dowels, and biscuits are popular options. These techniques provide excellent strength without sacrificing visuals.
Gather Your Tools
Choosing the right tools makes a remarkable difference when working with live-edge slabs. Essential tools include a circular saw, rounded chisel, nylon or wire brush, and rotary tool. Sanding techniques play a vital role in finishing live-edge surfaces. Hence, various sanding flap wheels catering to various grits come in handy.
Sand the Live-Edge Pieces
Begin the sanding process using a sanding flap wheel for the rotary tool, with grits ranging from 120 to 220. Progress to manual sanding with sandpaper ranging from 80 to 320 grit. Always start with a lower grit sandpaper and work your way up gradually. This approach aids in eliminating any material remaining from the saw cuts and shaping the edges to your preference.
Apply the Right Finish
Finishing options include tung oil, wax, clear polyurethane, shellac, or wood oil. The choice depends on the look you're aiming for; for instance, polyurethane gives a glossy finish, while wood oil results in a matte finish.
Apply your chosen finish with even, long strokes, and let it dry completely before applying subsequent coats. Each layer should be thin, allowing it to dry thoroughly. Sand gently using sandpaper between layers to achieve a uniform finish.
Protecting Your Live-Edge Creations
The first step to preserving live-edge surfaces involves addressing potential splits and cracks. First, seal the underside of the splits using Tyvek tape. When filling cracks, use epoxy resin with a small amount of black dye to blend the sealant with the natural color scheme of your live-edge wood. Limit each pour to 1/8th inch to avoid overheating.
To ensure the longevity of your live-edge pieces, regularly inspect them and apply protective finishes like polyurethane or wood oil. Regular dusting and periodic deep cleaning with diluted soapy water will also help maintain their appearance.
