What Is Resawing On A Table Saw?
Resawing is the process of cutting a board along its thickness to yield two or more thinner pieces, effectively ‘slicing’ lumber into slabs. While bandsaws are typically associated with this operation, the table saw is an accessible and accurate alternative, especially in home workshops lacking industrial-sized equipment.
Using a table saw for resawing is convenient for boards up to a certain height, usually dictated by the saw’s blade capacity. This versatility makes the technique especially valuable for cabinetmakers, woodworkers, and DIY enthusiasts aiming to create panels, veneers, or bookmatched surfaces.
Benefits Of Resawing On A Table Saw
- Maximizes Wood Use: Transform thick lumber into several thinner boards, achieving greater yield and reducing waste.
- Custom Thickness: Allows for precise control over finished board thickness for specific project requirements.
- Creative Applications: Enables production of bookmatched panels, decorative veneers, and matched grain surfaces for furniture and cabinetry.
- Cost Savings: Create expensive thin stock or veneers from affordable thick lumber, reducing material costs.
Essential Table Saw Setup For Safe And Accurate Resawing
Proper table saw setup is crucial for clean, safe, and accurate resawing. The following elements are key for preparing your tool and workspace:
Choose The Right Blade
- Rip Blades: Use a full kerf or thin kerf rip blade (24-40 teeth) with deep gullets to optimize chip removal and reduce burning.
- Carbide-Tipped Blades: Improve cut longevity and reduce heat buildup.
- Blade Height: Set blade height just above the material by about 1/4 inch to ensure efficient cutting.
Fence And Support Accessories
- High Auxiliary Fence: Attach a taller fence to your existing table saw fence to fully support the board during vertical resawing.
- Featherboards: Use to hold the board tightly against the fence and minimize blade drift or kickback risk.
- Outfeed Support: Set up additional stands or tables to handle long boards and prevent binding.
Safety Gear And Precautions
- Push Sticks And Blocks: Essential for keeping hands away from the blade, especially for narrow or thin cuts.
- Blade Guard And Riving Knife: Reduce the chance of kickback and shield from flying debris.
- Hearing And Eye Protection: Wear safety goggles and noise-cancelling earmuffs for personal protection.
Step-By-Step: How To Resaw On A Table Saw
Follow this practical guide to achieve smooth, uniform resaw cuts with minimal waste:
1. Measure And Mark The Cut Line
- Accurate Layout: Use a marking gauge or pencil to clearly mark the desired thickness across the edge and face of your board.
- Extend the line all the way around to help monitor consistency during the cut.
2. Set Blade And Fence
- Adjust Blade Height: Raise the blade 1/4 inch above the stock’s surface.
- Align The Fence: Set the table saw fence to match your desired board thickness using a precise ruler or caliper.
- Add a high auxiliary fence if working with tall stock for more stability.
3. Attach Safety Accessories
- Install featherboards before the blade to keep the wood pressed against the fence.
- Position outfeed support directly behind the saw to catch long or heavy boards as you cut.
4. Make The First Cut
- Turn on the table saw and stand to the side of the blade, not directly behind it.
- Feed the board slowly and steadily, using push sticks or blocks for control.
- Stop cutting when the halfway point is reached or just before the board can no longer be safely controlled.
5. Flip And Complete The Cut
- Turn off the saw and unplug it.
- Rotate the board end-to-end and repeat the cut from the other side, aligning with your marked line.
- This technique prevents binding and ensures a clean through-cut, especially useful if the blade can’t cut through in a single pass.
6. Smooth The Cut Faces
- After resawing, expect some saw marks or minor burning.
- Use a thickness planer, drum sander, or hand plane to remove roughness and achieve a smooth, even finish.
Key Resawing Techniques For Best Results
Consistency and correct technique ensure successful resawing on a table saw. Follow these tips to refine your process:
- Flat, Sqaure Lumber: Always joint and plane one face and one edge of the board before resawing for accuracy.
- Relieve Internal Stress: If possible, let the wood acclimate to your workshop for a few days beforehand to minimize warping after cutting.
- Monitor Feed Rate: Steady, even pressure helps avoid burning and blade binding. Never force the wood through the blade.
- Blade Alignment: Double-check your blade-to-fence alignment to eliminate drifting and wandering cuts.
Common Challenges And How To Solve Them
| Issue | Possible Cause | Solution |
|---|---|---|
| Blade Drift | Fence not parallel; blade misalignment | Realign fence; check and tune table saw blade |
| Burn Marks | Dull blade; feeding too slow; sticky resin | Sharpen or replace blade; increase feed rate; clean blade |
| Binding Or Kickback | Twisting wood; incorrect fence pressure | Use featherboards; keep stock square; proper push sticks |
| Uneven Thickness | Crooked cuts; warped boards | Start with jointed/planed lumber; use a jig or sled |
Maximizing Safety When Resawing On Table Saw
Prioritizing safety is critical when performing resaw cuts, as the process involves cutting tall boards upright through a spinning blade.
- Reduce Kickback Risks: Always use a riving knife and keep hands away from the blade path.
- Use Proper Support: Never allow lumber to tip or twist during the cut – featherboards and push blocks are essential.
- Never Remove Guard Unless Necessary: Only remove blade guards when the setup requires and always replace them immediately after.
- Stay Focused: Avoid distractions and never rush the process. If the wood binds, shut off the saw and investigate the cause before continuing.
When To Use Resawing With Table Saw Instead Of Bandsaw
The table saw is preferred for resawing when cutting boards up to the blade’s maximum height, typically 3 to 4 inches for contractor saws and up to 5 inches on cabinet models. For wider lumber, a band saw is often more efficient, but the table saw offers highly repeatable accuracy and cleaner cuts for boards within its capability.
Advantages of using a table saw include:
- Better dust collection.
- More precise rip fence adjustment.
- Smoother cut surfaces requiring less finishing.
When exceeding the saw’s height limits or working with very thick hardwoods, consider a bandsaw for safer and easier results.
Types Of Cuts And Projects Suited To Resawing On Table Saw
- Bookmatched Panels: Perfect for cabinet doors, tabletops, and drawer fronts with mirrored grain patterns.
- Veneer Production: Slice thin, uniform veneers for fine furniture, marquetry, or custom woodworking inlays.
- Thickness Reduction: Transform 8/4 lumber into two 3/4-inch boards, maximizing expensive hardwoods.
- Edge Banding: Create your own matching edge strips for plywood shelves or tabletops.
Selecting The Best Wood Species For Resawing
Not all hardwoods and softwoods behave equally during resawing. Some are prone to tearing, burning, or excessive blade dulling. Popular resaw-friendly species include:
- Maple and Birch: Dense but stable; produce clean, crisp resawn faces.
- Walnut and Cherry: Excellent for decorative veneers and bookmatching.
- Ash and Oak: Sturdy but open-grained; require sharp blades for best results.
- Pine and Poplar: Softer but occasionally gummy – clean blade regularly to reduce burning.
Using Jigs, Sleds, And Accessories To Improve Resawing Accuracy
Professional woodworkers frequently employ custom jigs and sleds for safer, more precise resawing.
Resaw Sleds
- Provide a flat, secure base to hold boards vertically against the saw’s fence.
- Incorporate clamps or stop blocks for repeatability and to prevent movement during cutting.
Zero-Clearance Inserts
- Support the workpiece directly at the blade, minimizing tearout and reducing the chance of small offcuts catching between the plate and blade.
Shop-Built Featherboards
- Homemade featherboards are simple, inexpensive, and clamp directly to the saw table or fence for custom setups.
Blade Maintenance And Tool Care For Better Resawing Results
Dull, dirty, or misaligned blades result in poor quality cuts and increased safety hazards.
- Clean the blade regularly with pitch and resin remover to prevent burning and reduce stress on the motor.
- Sharpen or replace blades when you notice increased effort, burning, or rough edges.
- Check alignment often: the blade and fence should be perfectly parallel and the arbor nut secure to avoid vibration.
