What bandsaw blade is best for resawing: Resawing is a critical woodworking task that involves cutting wood into thinner slabs or veneers while maintaining accuracy and efficiency. Selecting the right bandsaw blade is paramount for achieving optimal results. Below is a guide to the essential factors to consider:
1. Recommended TPI: 2-3 Variable TPI in Bi-Metal
The most popular choice for resawing is a 2-3 variable TPI blade, especially in bi-metal.
- Low TPI (2-3): Fewer teeth allow for larger gullets, facilitating efficient chip removal and preventing the blade from overheating during extended cuts.
- Bi-Metal Construction: Enhances blade durability and longevity, even under the stress of cutting dense or thick stock.
2. Key Blade Features for Resawing
Tooth Pattern
- Skip Tooth Pattern: Features widely spaced teeth with shallow gullets, promoting smooth material removal and reducing blade binding.
- Hook Tooth Pattern: Includes aggressive, forward-angled teeth for faster, more aggressive cuts through dense materials.
Tooth Set
- A wider tooth set creates a larger kerf (cut width), reducing the risk of blade pinching in the wood and ensuring smoother, more controlled cuts.
- This configuration enhances chip clearance, vital for maintaining cut quality in thick stock.
Blade Width
- A wider blade (e.g., 3/4” to 1”) offers greater stability, minimising deflection and ensuring straighter cuts during resawing.
- Wider blades handle higher tension, which is necessary for cutting through thicker or denser materials.
Material Composition
- Carbon Steel Blades: Affordable and suitable for softwoods, but prone to faster wear.
- Bi-Metal Blades: Offer superior durability, maintaining sharpness and performance even in hardwoods or frequent resawing applications.
3. Blade Maintenance for Resawing
To maintain consistent performance:
- Proper Tensioning: Ensure the blade is tensioned according to the manufacturer’s recommendations for straighter cuts and reduced deflection.
- Lubrication: Use lubricants to reduce friction and heat buildup during extended cutting sessions.
- Cleaning: Regularly clean blade teeth to prevent pitch buildup, which can dull the blade and affect cut quality.
Conclusion
The best bandsaw blade for resawing is one that balances low TPI, durability, and stability to achieve smooth, efficient cuts. A 2-3 variable TPI bi-metal blade with a skip or hook tooth pattern, a wide tooth set, and a sturdy blade width will provide the ideal combination of performance, precision, and longevity. Proper blade maintenance further ensures consistent results in your resawing projects.
