A bandsaw is primarily sized by the diameter of its wheels, a crucial measurement that dictates the machine's overall capacity for various cutting tasks.
Understanding Band Saw Sizing Metrics
When evaluating or purchasing a bandsaw, several key dimensions are used to define its capabilities. These measurements help users determine the maximum size of material the saw can effectively process.
Nominal Sizing: Wheel Diameter
The most fundamental way a bandsaw is sized is by the diameter of its wheels. These wheels guide the blade, and their size directly correlates with the saw's frame size and power. For example, a "14-inch bandsaw" signifies that the wheels guiding the blade are 14 inches in diameter. This nominal size provides a quick reference for the machine's general scale and power.
Throat Width
Closely related to the wheel diameter is the throat width. This measurement defines the widest board that can be passed between the blade and the main column of the saw. As the reference states, the throat width is typically "immediately recognizable as about 1″ less" than the wheel diameter. So, a 14-inch bandsaw would generally have a throat width of approximately 13 inches, allowing it to handle boards up to that width for cross-cutting or ripping operations.
Resaw Capacity
Beyond the width, another critical dimension is the resaw capacity. This refers to the maximum height (thickness) that can be cut by the bandsaw. Resawing is the process of cutting a thick piece of wood into thinner slices, often used to create veneers or thinner lumber from larger stock. A bandsaw's resaw capacity is determined by the maximum distance between the table and the upper blade guide, which can sometimes be extended on certain models.
Summary of Bandsaw Sizing Dimensions
| Dimension | Definition | Relationship to Other Metrics |
|---|---|---|
| Wheel Diameter | The diameter of the wheels that guide the bandsaw blade. | This is the nominal size of the bandsaw. |
| Throat Width | The maximum width of material that can pass between the blade and the saw's column. | Approximately 1″ less than the wheel diameter. |
| Resaw Capacity | The maximum height (thickness) of material that can be cut. | Independent of wheel diameter or throat width, but crucial for cutting thick stock or veneers. |
Understanding these three key dimensions — wheel diameter, throat width, and resaw capacity — is essential for selecting a bandsaw that meets specific woodworking or metalworking needs.
