When it comes to cutting plywood with a circular saw, it’s essential to have the right setup. One of the most important aspects of this setup is the material that you put under the plywood. Not only can this material help protect your work surface, but it can also make it easier to cut accurately and safely. So, what do you put under plywood when cutting with a circular saw? Let’s take a closer look.
First and foremost, it’s crucial to have a stable work surface when cutting plywood. This means that your saw needs to be securely mounted or clamped down, and the work surface should be level and free from any debris. Once you have your saw and work surface set up, it’s time to consider what you’ll be using under the plywood.
One popular option is to use a piece of sacrificial material, such as MDF or particleboard, under the plywood. This material is inexpensive and easy to find at most hardware stores. The sacrificial material should be cut to the same size as the plywood, and then secured to the work surface using clamps or screws.
The benefit of using sacrificial material is that it protects your work surface from damage caused by the circular saw blade. As you cut through the plywood, the blade will also cut into the sacrificial material, which can be easily replaced once it’s too damaged to use anymore. This method is particularly useful if you’re cutting a lot of plywood and want to protect your work surface.
Another option is to use foam insulation board or foam matting under the plywood. This material is also relatively inexpensive and can be found at most hardware stores. The foam board should be cut slightly larger than the plywood to provide a cushioned surface to cut on.
The benefit of using foam insulation board is that it provides a softer surface to cut on, which can help prevent the blade from chipping or splintering the plywood. It also helps to reduce the noise and vibration caused by the circular saw. However, foam insulation board is not as durable as sacrificial material and may need to be replaced more frequently.
Finally, some woodworkers prefer to use a combination of sacrificial material and foam insulation board under the plywood. This method provides the best of both worlds, offering protection to the work surface while also providing a cushioned cutting surface.
No matter which material you choose to use under your plywood, it’s essential to make sure that it’s securely fastened to the work surface. The last thing you want is for the material to shift or move while you’re cutting, which can lead to inaccurate cuts or even injury.
In conclusion, when cutting plywood with a circular saw, it’s important to have a stable work surface and the right material underneath the plywood. Whether you choose to use sacrificial material, foam insulation board, or a combination of both, make sure that it’s securely fastened to the work surface and provides a cushioned surface to cut on. With the right setup, you can achieve accurate and safe cuts every time.

Frequently Asked Questions About What To Put Under Plywood When Cutting With A Circular Saw
1. Why do I need to put something under plywood when cutting with a circular saw?
Putting something under the plywood when cutting with a circular saw helps prevent tear-out and splintering. It also protects the cutting surface underneath from damage.
2. What can I use to put under plywood when cutting with a circular saw?
There are several things you can use to put under plywood when cutting with a circular saw, including a sawhorse, a sheet of foam insulation, or a piece of scrap plywood.
3. How do I choose the best material to put under plywood when cutting with a circular saw?
When choosing a material to put under plywood when cutting with a circular saw, consider the thickness of the material, its ability to absorb vibrations, and its ability to provide a non-slip surface. It is also important to choose a material that is strong enough to support the weight of the plywood.
4. Can I use a piece of cardboard or a towel under plywood when cutting with a circular saw?
While you can use a piece of cardboard or a towel under plywood when cutting with a circular saw, it is not recommended. These materials are not strong enough to support the weight of the plywood and can shift during cutting, leading to inaccurate cuts and potential safety hazards.
