Bandsaw Resaw Jig Build (Pro Tips for Firewood Upcycling)

Safety First: A Word of Caution Before We Begin

Before we dive into the nitty-gritty of building a bandsaw resaw jig for upcycling firewood, let’s address the elephant in the room: safety. Working with power tools, especially bandsaws, demands respect and a healthy dose of caution. I’ve seen firsthand the damage a momentary lapse in concentration can cause, and believe me, it’s not pretty.

• Eye Protection is Non-Negotiable: Flying wood chips and sawdust are a constant hazard. Invest in a good pair of safety glasses or a face shield.
• Hearing Protection is Your Friend: The high-pitched whine of a bandsaw can cause long-term hearing damage. Wear earplugs or earmuffs.
• Dust Collection is Essential: Sawdust is not only a nuisance but also a health hazard. Use a dust collector or wear a respirator, especially when working with treated wood.
• Know Your Machine: Read the manufacturer’s manual thoroughly and understand the bandsaw’s capabilities and limitations.
• Never Force the Cut: Let the blade do the work. Forcing the cut can lead to kickback or blade breakage.
• Keep Your Hands Clear: Maintain a safe distance between your hands and the blade. Use push sticks or feather boards to guide the wood.
• Unplug Before Adjusting: Always disconnect the power before making any adjustments or changing the blade.
• Inspect Your Work Area: Ensure the area is well-lit, free of clutter, and has a stable surface.
• Stay Focused: Avoid distractions and take breaks when needed. Fatigue can lead to mistakes.
• Dress Appropriately: Avoid loose clothing, jewelry, or long hair that could get caught in the machinery.

Introduction: Why a Bandsaw Resaw Jig for Firewood Upcycling?

In my years of woodworking and firewood processing, I’ve always been fascinated by the potential hidden within seemingly unusable pieces of wood. Firewood, often relegated to the flames, can be a treasure trove of unique grains, colors, and character. But unlocking this potential requires the right tools and techniques.

That’s where the bandsaw and a well-designed resaw jig come into play. A bandsaw allows you to slice thicker pieces of wood into thinner ones, a process known as resawing. This opens up a world of possibilities for upcycling firewood, from creating thin veneers for decorative projects to crafting small boxes, turning blanks, or even instrument parts.

However, resawing on a bandsaw can be challenging, especially with uneven or warped pieces of firewood. That’s where a resaw jig becomes indispensable. It provides a stable and controlled platform for guiding the wood through the blade, ensuring consistent thickness and minimizing the risk of kickback or blade drift.

In this article, I’ll share my experience and insights on building a bandsaw resaw jig specifically tailored for upcycling firewood. I’ll walk you through the design considerations, construction steps, and pro tips that will help you create a jig that is accurate, safe, and versatile. But more importantly, I will help you understand the science behind why we do what we do.

Understanding the Wood: A Foundation for Success

Before we start building the jig, it’s crucial to understand the material we’ll be working with: wood. Different species have different properties that affect how they cut, dry, and behave.

Hardwood vs. Softwood: A Simplified Distinction

The terms “hardwood” and “softwood” are botanical classifications, not necessarily indicators of the wood’s actual hardness. Hardwoods come from deciduous trees (trees that lose their leaves annually), while softwoods come from coniferous trees (trees that typically have needles and cones).

• Hardwoods: Generally denser and more complex in structure, hardwoods like oak, maple, cherry, and walnut are prized for their strength, durability, and aesthetic appeal. They tend to be more challenging to cut and require sharper blades.
• Softwoods: Softer and less dense than hardwoods, softwoods like pine, fir, cedar, and redwood are easier to work with and often used in construction and furniture making. They tend to dull blades faster due to their resin content.

Wood Anatomy: The Cellular Structure

Wood is composed of cells, primarily cellulose, hemicellulose, and lignin. The arrangement and characteristics of these cells determine the wood’s properties.

• Cellulose: The primary structural component of wood, providing strength and rigidity. It is a polymer of glucose molecules.
• Hemicellulose: A branched polysaccharide that binds cellulose fibers together. It is more susceptible to degradation than cellulose.
• Lignin: A complex polymer that provides rigidity and resistance to decay. It is responsible for the brown color of wood.
• Growth Rings: The annual layers of wood added by the tree, visible as concentric rings in a cross-section. The width and density of the rings reflect the growing conditions during that year.
• Grain: The direction of the wood fibers, which affects its appearance and strength. Straight-grained wood is easier to work with than wood with knots or irregular grain.

Moisture Content: The Key to Stability

Moisture content (MC) is the amount of water in wood, expressed as a percentage of its oven-dry weight. MC significantly affects wood’s dimensional stability, strength, and susceptibility to decay.

• Green Wood: Wood that has been freshly cut and has a high MC (often above 30%). Green wood is heavy, difficult to work with, and prone to warping and cracking as it dries.
• Air-Dried Wood: Wood that has been allowed to dry naturally in the air. Air-drying typically reduces the MC to around 12-15%, depending on the climate.
• Kiln-Dried Wood: Wood that has been dried in a controlled environment using heat and air circulation. Kiln-drying can reduce the MC to as low as 6-8%, making the wood more stable and less prone to movement.
• Equilibrium Moisture Content (EMC): The MC that wood will eventually reach in a particular environment. EMC varies depending on the temperature and humidity.

Data Point: According to the USDA Forest Service, wood shrinks or swells approximately 1% for every 4% change in moisture content below the fiber saturation point (around 28-30% MC).

Unique Insight: Understanding MC is especially crucial when upcycling firewood. Firewood is often stored outdoors and can have a wide range of MC, depending on the species, storage conditions, and drying time. Resawing firewood with high MC can lead to warping and uneven cuts. It’s best to let firewood dry for at least six months before resawing it.

Case Study: The Impact of Moisture Content on Resawing

I once tried to resaw some green oak firewood into thin veneers for a marquetry project. Despite using a sharp blade and a well-built jig, the veneers warped and twisted as they dried, rendering them unusable. I learned the hard way that moisture content is the most important factor when resawing wood.

Designing Your Bandsaw Resaw Jig: Considerations and Features

Now that we have a basic understanding of wood, let’s move on to designing the resaw jig. The goal is to create a jig that provides a stable, controlled, and repeatable way to guide the wood through the bandsaw blade.

Key Design Considerations

• Stability: The jig must be stable and resist movement during the cut. This is especially important when resawing uneven or warped pieces of firewood.
• Adjustability: The jig should be adjustable to accommodate different thicknesses of wood.
• Accuracy: The jig must guide the wood accurately to ensure consistent thickness of the resawn pieces.
• Safety: The jig must be designed to keep your hands away from the blade and minimize the risk of kickback.
• Versatility: The jig should be versatile enough to handle different sizes and shapes of firewood.

Essential Features of a Resaw Jig

• Base: A solid and stable base that rests on the bandsaw table.
• Fence: A vertical guide that runs parallel to the blade and provides a reference surface for the wood.
• Adjustable Height: The fence should be adjustable in height to accommodate different thicknesses of wood.
• Hold-Down: A mechanism to hold the wood firmly against the fence and prevent it from lifting during the cut.
• Feather Board: A springy piece of wood that applies pressure to the wood, keeping it tight against the fence and preventing kickback.
• Push Stick: A handle used to push the wood through the blade, keeping your hands safely away.

Design Options and Variations

There are many different ways to design a resaw jig, depending on your bandsaw, the type of firewood you’ll be working with, and your personal preferences. Here are a few options to consider:

• Fixed Fence Jig: A simple jig with a fixed fence height. This is a good option for resawing wood of a consistent thickness.
• Adjustable Fence Jig: A more versatile jig with an adjustable fence height. This allows you to resaw wood of different thicknesses.
• T-Track Jig: A jig that uses T-tracks to mount the fence and hold-down. This allows for easy adjustment and customization.
• Magnetic Jig: A jig that uses magnets to hold the fence in place. This is a good option for quick and easy adjustments.
• Roller Jig: A jig that uses rollers to support the wood as it passes through the blade. This can reduce friction and improve the smoothness of the cut.

Personalized Story: My Evolution of Resaw Jigs

My first resaw jig was a simple piece of plywood clamped to the bandsaw table. It worked, but it was far from ideal. The fence wasn’t perfectly straight, the wood tended to wander, and I felt like I was constantly fighting the saw.

Over the years, I’ve built several different resaw jigs, each one an improvement over the last. I’ve experimented with different materials, fence designs, and hold-down mechanisms. My current jig is a T-track design with an adjustable fence, a feather board, and a magnetic hold-down. It’s the most accurate and versatile jig I’ve ever used, and it has made resawing firewood a much more enjoyable and efficient process.

Building Your Bandsaw Resaw Jig: Step-by-Step Instructions

Now that you have a design in mind, let’s start building your resaw jig. I’ll provide step-by-step instructions for building a T-track jig with an adjustable fence, a feather board, and a magnetic hold-down.

Materials List

• Plywood: ¾” plywood for the base, fence, and hold-down.
• T-Track: Two lengths of T-track for mounting the fence and hold-down.
• Knobs and Bolts: For adjusting the fence height and tightening the hold-down.
• Magnets: Strong magnets for the magnetic hold-down.
• Feather Board: A pre-made feather board or material to make your own.
• Wood Screws: For assembling the jig.
• Wood Glue: For added strength.

Tools List

• Bandsaw: Of course!
• Table Saw: For cutting the plywood to size.
• Drill: For drilling holes for the T-tracks, knobs, and bolts.
• Countersink Bit: For countersinking the screw holes.
• Screwdriver: For driving the screws.
• Clamps: For holding the pieces together while the glue dries.
• Measuring Tape: For accurate measurements.
• Square: For ensuring the fence is square to the base.

Step-by-Step Instructions

1. Cut the Base: Cut a piece of plywood to the desired size for the base. I recommend a size that is slightly larger than your bandsaw table.
2. Install the T-Tracks: Rout or dado two grooves in the base for the T-tracks. The grooves should be parallel to the blade and spaced far enough apart to accommodate the fence and hold-down. Secure the T-tracks in the grooves with screws.
3. Cut the Fence: Cut a piece of plywood to the desired size for the fence. The fence should be tall enough to accommodate the thickest piece of firewood you plan to resaw.
4. Attach the Fence to a Sliding Base: Cut a piece of plywood that slides in the T-Track. Attach the fence to this piece.
5. Drill Holes for the Adjustment Knobs: Drill holes in the fence and sliding base for the adjustment knobs. The holes should be spaced evenly apart and allow for a range of fence heights.
6. Install the Adjustment Knobs: Insert bolts through the holes in the fence and sliding base, and secure them with knobs. This will allow you to adjust the height of the fence.
7. Build the Hold-Down: Cut a piece of plywood to the desired size for the hold-down. Attach magnets to the bottom of the hold-down.
8. Install the Feather Board: Attach the feather board to the base of the jig, in front of the blade. The feather board should apply pressure to the wood, keeping it tight against the fence.
9. Test the Jig: Place the jig on your bandsaw table and test it with a piece of scrap wood. Make sure the fence is square to the blade and the hold-down is applying enough pressure.

Detailed Data Point: Calculating Fence Height

To determine the optimal height of your fence, consider the following formula:

• Fence Height = Maximum Firewood Thickness + Blade Height + Clearance

  • Maximum Firewood Thickness: The thickest piece of firewood you plan to resaw.
  • Blade Height: The height of your bandsaw blade above the table.
  • Clearance: An additional inch or two to allow for uneven surfaces or slight variations in thickness.

Example: If you plan to resaw firewood up to 6 inches thick and your blade height is 2 inches, your fence height should be at least 9 inches (6 + 2 + 1 = 9).

Unique Insight: The Importance of a Sharp Blade

A sharp blade is essential for accurate and efficient resawing. A dull blade will wander, create a rough surface, and require more force to push the wood through the saw. I recommend using a blade specifically designed for resawing, with a low tooth count (3-4 TPI) and a hook angle.

Resawing Firewood: Techniques and Tips

With your resaw jig built, you’re ready to start resawing firewood. Here are some techniques and tips to help you get the best results:

Blade Selection

• Tooth Count (TPI): For resawing, a low TPI (3-4) is ideal. This allows for efficient chip removal and reduces the risk of clogging.
• Blade Width: A wider blade (½” or ¾”) provides more stability and reduces blade wander.
• Blade Material: High-carbon steel blades are suitable for most hardwoods and softwoods. Bi-metal blades are more durable and can handle tougher materials.
• Hook Angle: A hook angle of 10-15 degrees is recommended for resawing. This helps to pull the wood into the blade.

Bandsaw Setup

• Blade Tension: Proper blade tension is crucial for accurate cutting. Refer to your bandsaw’s manual for the recommended tension.
• Blade Guides: Adjust the blade guides so they are close to the blade but not touching it. This will help to support the blade and prevent it from wandering.
• Table Squareness: Ensure the bandsaw table is square to the blade. This will help to ensure that your cuts are accurate.
• Feed Rate: Feed the wood through the blade at a steady and consistent rate. Avoid forcing the cut, which can lead to kickback or blade breakage.

Resawing Techniques

• Start with a Flat Face: If the firewood has an uneven surface, flatten one face using a jointer or hand plane. This will provide a stable reference surface for the jig.
• Adjust the Fence Height: Adjust the fence height to the desired thickness of the resawn piece.
• Use a Push Stick: Always use a push stick to push the wood through the blade, keeping your hands safely away.
• Watch for Blade Drift: If the blade starts to wander, stop the saw and adjust the fence or the feed rate.
• Relieve Tension: For thicker pieces of firewood, it may be necessary to relieve tension in the wood by making kerf cuts on the back side of the piece. This will prevent the wood from binding on the blade.
• Resaw in Stages: For very thick pieces of firewood, it may be necessary to resaw in multiple stages, gradually increasing the fence height.

Data Point: Feed Rate Optimization

The optimal feed rate for resawing depends on the species and thickness of the wood, the blade type, and the power of your bandsaw. As a general rule, start with a slow feed rate and gradually increase it until you find the sweet spot.

• Softwoods: Can typically be resawn at a faster feed rate than hardwoods.
• Thick Wood: Requires a slower feed rate than thin wood.
• Sharp Blade: Allows for a faster feed rate than a dull blade.

Statistic: Studies have shown that optimizing feed rate can increase resawing efficiency by up to 20%.

Personalized Experience: My Biggest Resawing Mistake

I once tried to resaw a large piece of oak firewood without relieving the tension in the wood. As I got closer to the end of the cut, the wood started to bind on the blade, causing the saw to stall and the blade to break. It was a scary experience, and it taught me the importance of relieving tension and taking my time.

I finished the tabletop with a clear epoxy resin to highlight the grain and protect the wood. The coffee table is now a centerpiece in my living room, and it’s a constant reminder of the potential hidden within seemingly ordinary materials.

Firewood Seasoning Techniques and Safety Considerations

Firewood seasoning is the process of drying firewood to reduce its moisture content. Seasoned firewood burns more efficiently, produces more heat, and creates less smoke.

Why Season Firewood?

• Increased Efficiency: Seasoned firewood has a lower moisture content, which means more of the energy from combustion is used to produce heat, rather than evaporating water.
• Higher Heat Output: Seasoned firewood produces more heat per unit volume than green firewood.
• Reduced Smoke: Seasoned firewood burns cleaner and produces less smoke, which reduces air pollution and improves the efficiency of your wood-burning appliance.
• Creosote Reduction: Seasoned firewood produces less creosote, a flammable substance that can build up in chimneys and cause chimney fires.

Seasoning Methods

• Air-Drying: The most common method of seasoning firewood. It involves stacking the firewood in a well-ventilated area and allowing it to dry naturally in the air.
• Kiln-Drying: A faster method of seasoning firewood that involves drying the wood in a controlled environment using heat and air circulation.
• Solar Kiln: A type of kiln that uses solar energy to heat the air and dry the wood.

Air-Drying Best Practices

• Stacking: Stack the firewood in a single row, with the pieces oriented perpendicular to the prevailing wind.
• Elevation: Elevate the firewood off the ground using pallets or timbers.
• Spacing: Leave space between the rows to allow for air circulation.
• Covering: Cover the top of the stack to protect it from rain and snow.
• Location: Choose a location that is sunny and well-ventilated.

Seasoning Time

The amount of time it takes to season firewood depends on the species of wood, the climate, and the seasoning method. As a general rule, hardwoods take longer to season than softwoods.

• Softwoods: Typically take 6-12 months to season.
• Hardwoods: Typically take 12-24 months to season.

Data Point: According to the US Forest Service, properly seasoned firewood should have a moisture content of 20% or less.

Safety Considerations

• Stacking Safety: Stack the firewood in a stable manner to prevent it from collapsing.
• Pest Control: Inspect the firewood for pests such as termites or carpenter ants.
• Fire Safety: Store the firewood away from your house or other structures to prevent the spread of fire.

Logging Tool Selection and Maintenance Best Practices

While upcycling firewood often involves using wood that’s already been processed, it’s still helpful to understand the tools used in logging and wood processing. This knowledge can inform your firewood selection and preparation techniques.

Chainsaws

• Types: Gas-powered, electric, and battery-powered.
• Selection Criteria: Bar length, engine size, weight, and safety features.
• Maintenance: Sharpening the chain, cleaning the air filter, checking the spark plug, and lubricating the bar and chain.
• Safety: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, and chaps.

Axes and Mauls
