A bandsaw is a versatile power tool used for sawing various materials, most commonly wood, metal, and plastic. It consists of a continuous band of toothed metal stretched between two or more wheels to cut material. This band saw blade travels in a continuous loop, allowing for uniform cutting action and the ability to make both straight and irregular or curved cuts with precision.

Bandsaws are available in various sizes, from small benchtop models to large floor-standing industrial machines. The size of a bandsaw is typically determined by the diameter of the wheels and the throat, which is the distance from the blade to the vertical frame section of the saw. This determines the maximum width of material that can be cut.

One of the key advantages of a bandsaw over other types of saws is its ability to make intricate cuts without needing to start from the edge of the material. This makes it particularly useful for woodworking, metalworking, and in the construction of complex parts or artistic pieces. Additionally, because the blade of a bandsaw moves in a downward motion, there is less tendency for the material being sawed to move or shift during cutting, resulting in more accurate and cleaner cuts.

Using a bandsaw effectively and safely requires understanding its basic operation, setting it up properly, and following safety guidelines. Here’s a step-by-step guide on how to use a bandsaw:

1. Safety First

  • Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and dust masks.
  • Ensure long hair is tied back, and avoid loose clothing or jewelry that could get caught in the machine.

2. Inspect and Prepare the Bandsaw

  • Check the bandsaw for any signs of wear or damage. Ensure the blade is sharp, properly tensioned, and appropriate for the material and type of cut you plan to make.
  • Adjust the blade guide and guard according to the thickness of the material being cut, ensuring it’s just above the material’s surface to minimize blade exposure.

3. Set Up Your Workpiece

  • Securely clamp or firmly hold your material in place. If the piece is small or irregularly shaped, consider using a jig or push stick to keep your hands safely away from the blade.

4. Make the Cut

  • Power on the bandsaw and let it reach full speed before beginning your cut.
  • Feed the material into the blade gently, guiding it along the marked line if you’re making a precise cut. Maintain a steady feed rate that allows the blade to cut without forcing or binding.
  • Keep your fingers and hands at a safe distance from the blade at all times. Use push sticks or push blocks for close work.

5. Manage Curves and Corners

  • For curves, make relief cuts to remove excess material and reduce the stress on the blade. Turn the workpiece gently, keeping the feed rate consistent without twisting or bending the blade.
  • For tight corners, you may need to stop the saw, back the material out carefully, and then start the cut again from a different angle.

6. Finishing Up

  • Once the cut is complete, allow the blade to stop completely before removing the workpiece or making adjustments.
  • Turn off the bandsaw, disconnect it from power, and clean up any debris or sawdust.

Additional Tips

  • Regularly check and adjust the blade tension and tracking to ensure optimal performance.
  • Use the right blade for the material and type of cut. For example, use a finer tooth blade for metal and plastic, and a coarser blade for wood.
  • Practice on scrap material if you’re new to using a bandsaw to get a feel for the feed rate and blade behavior.

By following these steps and tips, you can safely and effectively use a bandsaw for a wide range of cutting tasks.

Choosing the right bandsaw involves considering several factors to ensure it meets your specific needs. Here’s a guide to help you make an informed decision:

The right bandsaw for you depends on the types of projects you undertake, the materials you work with, and the features that are most important to you. Assessing your needs and researching can lead to a purchase that enhances your ability to create and build with precision and efficiency.

A bandsaw works by using a continuous looped blade that is driven by two or more wheels to cut through material. Here’s a breakdown of its working mechanism:

Blade and Wheels: The bandsaw blade, a thin strip of metal with teeth on one edge, is looped around two or more wheels. These wheels are typically aligned vertically within the bandsaw frame, with one wheel above the work table and the other below it. At least one of these wheels is motor-driven to rotate, propelling the blade in a continuous loop.

Power Source: The bandsaw’s motor powers the rotation of the wheels and, consequently, the movement of the blade. The motor’s size and power output can vary depending on the bandsaw model, with larger bandsaws requiring more powerful motors to cut through thicker or harder materials.

Cutting Action: The blade moves in a downward direction on the front side of the bandsaw, where the material to be cut is positioned on the bandsaw’s table. This directional movement ensures that the material is firmly held against the table during cutting, reducing the likelihood of inaccuracies or the material moving.

Adjustable Table and Guide: The bandsaw table, where the material is placed for cutting, can typically be adjusted to various angles for making precise cuts at different angles. Blade guides above and below the table help keep the blade aligned and stable during cutting, ensuring precise and straight cuts. These guides can be adjusted depending on the thickness of the material being cut.

Variable Speed: Some bandsaws come with variable speed controls, allowing the user to adjust the speed of the blade depending on the type of material being cut. Slower speeds are often used for cutting metal or plastic to prevent overheating, while higher speeds can be used for wood.

Making the Cut: To make a cut, the user marks the material with the desired cut line, turns on the bandsaw, and then feeds the material into the blade, guiding it along the cut line. The bandsaw allows for both straight and curved cuts, making it exceptionally versatile for different types of projects.

Dust Collection: Many bandsaws are equipped with dust collection ports that allow for the attachment of a dust collector or shop vacuum. This helps in managing sawdust and keeping the work area clean.

By moving the material through the blade, rather than moving the blade through the material (as is common with handheld saws), bandsaws provide a stable and controlled cutting environment that is ideal for precise, intricate, and repetitive cutting tasks.

Choosing the right size bandsaw depends on several factors, including the type of projects you plan to undertake, the materials you’ll be cutting, and the space available in your workshop. Here are some guidelines to help you decide:

Throat Capacity
The throat capacity or throat depth of a bandsaw is the distance from the blade to the vertical frame section of the saw body. It determines the maximum width of material that you can cut.
For light-duty tasks, hobbyist projects, or if you’re working with smaller pieces of material, a bandsaw with a throat capacity of 12 to 14 inches might suffice.
For larger projects or if you plan to cut wider materials, look for a bandsaw with a throat capacity of 18 inches or more.
Resaw Capacity
Resaw capacity is the maximum height of material the bandsaw can cut. It’s important if you plan to slice thicker pieces of wood into thinner boards.
A larger resaw capacity is beneficial for tasks such as resawing lumber into thinner slabs or bookmatching. Bandsaws with a resaw capacity of 12 inches or more are ideal for these types of tasks.
Motor Power
Motor power is crucial, especially if you’re cutting through dense materials or require continuous use.
Light to medium projects typically require a motor power of 0.5 to 1.5 horsepower (HP).
For more demanding tasks, such as cutting through metal or hardwoods, or for industrial use, consider a bandsaw with a motor that has 2 HP or more.
Table Size and Features
The size of the bandsaw table is also an important consideration, as it supports the material during cutting. A larger table provides better support for bigger workpieces.
Some tables offer tilt capabilities, which are useful for making angled cuts. Consider a bandsaw with a table that tilts up to 45 degrees if you anticipate needing angled cuts.
Floor Standing vs. Benchtop
Floor standing bandsaws are larger, offer greater capacity and power, and are suited for professional or heavy-duty use. They’re the go-to choice for serious woodworkers or industrial applications.
Benchtop bandsaws are more compact and can be placed on a workbench. They’re suitable for hobbyists or those with limited space.

Ultimately, the “right” size bandsaw is one that fits your specific needs, the space you have available, and your budget. It’s worth considering future projects as well; a slightly larger and more capable bandsaw can provide more versatility and room to grow as your skills and projects evolve.

Adjusting a bandsaw correctly is crucial for optimal performance, accurate cuts, and safety. Here’s a comprehensive guide on how to adjust various components of your bandsaw:

1. Blade Tension
Correct tension is essential for precise cuts. Most bandsaws have a tension gauge, but they’re not always accurate. A general rule is to tighten the blade until it’s firm and doesn’t deflect more than about 1/4 inch when you push on it with moderate pressure.
For saws without a gauge, refer to the manual for specific recommendations on tension settings based on blade width.
2. Blade Tracking
Blade tracking refers to the alignment of the blade on the wheels. With the bandsaw unplugged, open the top wheel cover, and turn the wheel by hand. Adjust the tracking knob until the blade runs centered on the wheel’s crown. The blade should not drift toward the front or back of the wheel.
3. Blade Guides
Blade guides support the blade near the cut point. Adjust the side guides and the thrust bearing behind the blade so they are close to, but not touching, the blade. They should support the blade during a cut without hindering its movement.
4. Table Alignment
Square the table to the blade using a square. Loosen the table tilt adjustment, and adjust until the blade is perpendicular to the table. Tighten the adjustment to secure the table in place.
5. Fence Alignment
If your bandsaw has a fence, ensure it’s parallel to the blade’s path. This can usually be adjusted by loosening the fence mount and aligning the fence with the miter slot or another fixed point on the table.
6. Guide Post Height
Adjust the guide post height so the guides are just above the material being cut. This minimizes blade exposure and vibration for safer and more accurate cuts.
7. Checking for Square Cuts
After making these adjustments, test the saw by cutting a piece of wood. Check the cut for squareness and adjust the table tilt or guide settings if necessary.
Safety and Maintenance Tips
Always unplug the bandsaw before making adjustments.
Regularly check blade sharpness and replace dull blades to ensure clean cuts and reduce strain on the bandsaw.
Keep the bandsaw clean, including the wheels, guides, and table. Accumulated sawdust can affect performance and accuracy.
Lubricate moving parts as recommended by your bandsaw’s manual to keep them operating smoothly.
Adjusting a bandsaw is a continuous process. Wood species, humidity, and wear can affect its performance, so it’s a good practice to check these settings regularly and especially before starting a new project or after changing the blade. Always refer to your bandsaw’s manual for specific instructions and safety information.
