If you’re new to woodworking or looking to take on bigger projects, you may be wondering if it’s possible to put two blades on a table saw. It’s a fair question, and one that we’ll explore in this article. We’ll cover the benefits and drawbacks of using two blades, what kind of table saws can handle them, and how to do it safely.
Benefits of Using Two Blades on a Table Saw
Increased Cutting Depth
One of the main benefits of using two blades on a table saw is that it increases the cutting depth. This is especially useful when you’re working with thicker materials, such as hardwood or laminated sheets. With two blades, you can cut through the material in a single pass, rather than making multiple passes with a single blade.
Improved Cutting Quality
Another benefit of using two blades is that it improves the cutting quality. When you use two blades, the saw blade cuts the material twice, which creates a smoother cut with fewer rough edges. This is especially important when you’re working with materials that are prone to chipping, such as veneers or laminates.
Using two blades can also save you time, especially when you’re cutting large or complex pieces. With two blades, you can cut through the material faster, which means you can finish your projects more quickly.
Drawbacks of Using Two Blades on a Table Saw
Increased Risk of Injury
The most significant drawback of using two blades on a table saw is the increased risk of injury. With two blades, there is a higher risk of kickback, which is when the material is thrown back at you with great force. Kickback can cause serious injury, so it’s essential to take extra precautions when using two blades.
Difficulty in Setting Up and Aligning Blades
Another drawback of using two blades is that it can be challenging to set up and align the blades properly. This is especially true if you’re not experienced with using table saws. Improper blade alignment can cause poor cutting quality, kickback, and even damage to the saw.
Using two blades also comes with an additional cost. You’ll need to purchase an additional blade, and some table saws may require additional accessories to handle two blades. This can add up quickly, especially if you’re on a tight budget.
What Kind of Table Saws Can Handle Two Blades
Not all table saws can handle two blades. You’ll need a saw with a powerful motor and enough space to accommodate two blades. Typically, cabinet saws and contractor saws can handle two blades, while smaller benchtop saws cannot.
How to Safely Put Two Blades on a Table Saw
Adjust the Blade Height
Before installing the second blade, adjust the height of the first blade. You want the first blade to be slightly higher than the second blade, so it does the bulk of the cutting. The second blade should be set to cut just slightly below the surface of the material.
Align the Blades
Proper blade alignment is crucial when using two blades on a table saw. You want the blades to be perfectly parallel to each other and to the saw’s fence. Use a dial indicator to ensure that the blades are aligned correctly.
Test the Saw
Once the blades are installed and aligned, it’s essential to test the saw before using it on a project. Make sure the blades are spinning in the right direction, and test the saw’s performance on a scrap piece of material. If the saw performs as expected, you’re ready to start your project.
Using two blades on a table saw can be a game-changer for woodworkers looking to take on bigger projects. It can increase cutting depth, improve cutting quality, and save time. However, using two blades also comes with risks, including an increased risk of injury and additional cost. It’s crucial to use two blades safely and properly by choosing the right blades, adjusting the blade height, aligning the blades, and testing the saw before use.
Using two blades on a table saw can be safe if you take the proper precautions, such as choosing the right blades, adjusting the blade height, aligning the blades, and testing the saw before use.
