Adjust the blade depth to match the thickness of the plywood to avoid cutting too deep.

Supporting Plywood During Cuts

Use sawhorses or a sturdy workbench to support the plywood and prevent splintering.

Jigsaw For Curved Cuts

To trim plywood with curved cuts, a jigsaw is the ideal tool. Its ability to make intricate cuts makes it perfect for shaping plywood to fit any design. With the right blade, a jigsaw can easily slice through the wood, creating smooth curves and angles.

If you’re looking to add curves to your plywood project, a jigsaw is the perfect tool for the job. With a jigsaw, you can easily make both tight and gentle curves with precision and control. However, to ensure a successful cut, you need to choose the right blade and know how to navigate tight corners.

Choosing The Right Blade

When it comes to cutting plywood with a jigsaw, the type of blade you use is crucial. A blade with fewer teeth per inch (TPI) will be faster but leave a rougher finish. On the other hand, a blade with more TPI will be slower but result in a smoother cut. For plywood, a blade with around 10 TPI is a good choice.

Navigating Tight Curves And Corners

To navigate tight corners, you’ll need to make relief cuts. These are small cuts made near the corners that allow the blade to turn without binding. To make a relief cut, start by drilling a small hole in the waste area, then insert the blade and cut to the corner. From there, pivot the blade and continue cutting along the curve.

When making gentle curves, it’s important to keep the blade moving smoothly and at a consistent speed. Avoid stopping and starting, as this can result in jagged cuts. Instead, move the jigsaw slowly and steadily along the curve.

With the right blade and technique, a jigsaw can be a powerful tool for cutting curves in plywood. By following these tips, you can achieve precise, smooth cuts that add a professional finish to your project.
