How to cut a radius with a scroll saw:

Here are some steps to help you cut a radius on your scroll saw:

1. Decide the size of radius:

This is the first step in cutting a radius. You need to decide how big you want the curve to be. This can be difficult because it depends on the project you’re working on, but try to have a general idea before you start.

2. Find the center of the radius:

Once you know the size of your radius, you need to find the center point. This will be your guide for sewing around the curve.

3. Clamp down your workpiece:

Make sure your workpiece is clamped down securely before you start cutting. This will help keep it still and prevent any accidents.

4. Set up your saw:

Next, set up your scroll saw according to its instructions. You’ll need to make sure the blade is in the right place and that the table is at the correct height.

5. Cut along the centerline:

Now it’s time to start cutting! Make sure your saw is turned off before you start. Use a straight edge to help guide your cuts, and cut along the centerline of the radius.

6. Finish up the curve:

Once you’ve cut along the centerline, use your fingers or a piece of sandpaper to smooth out the curve. Be careful not to damage your workpiece while you’re doing this.

There you have it! Cutting a radius on a scroll saw is actually much simpler than it seems. Just follow these simple steps and you’ll be able to do it like a pro.

Safety Tips:

Here are some tips to help keep you safe when cutting a radius with a scroll saw:

Always use protective eyewear when cutting.

Make sure the blade is properly secured in the saw before starting.

Keep the hands and fingers clear of the blade at all times.

Slow down when making curves or corners to avoid mistakes.

Never try to force the wood through the saw if it’s not going smoothly.

Cut on a stable surface and make sure the wood is clamped down securely.

If possible, have another person help you hold the wood while you cut.

That’s it! Following these tips should help you safely cut a radius with your scroll saw.

Some Common mistakes:

Here are some common mistakes people make when cutting a radius with a scroll saw:

1. Not using a backer board:

When you’re cutting a curved piece of wood, it’s important to use a backer board to help support the wood and keep it from bending. This will ensure that your cuts are accurate and smooth.

2. Cutting too fast:

When you’re cutting a radius, it’s important to cut slowly and steadily to avoid mistakes. If you try to cut too quickly, you may end up with jagged or uneven edges.

3. Not clamping the wood in place:

It’s important to make sure that the wood is clamped down securely before making any cuts. This will help keep the wood in place and prevent it from moving or shifting while you’re cutting.

4. Not using the correct blade:

When cutting a radius, it’s important to use a blade that is specifically designed for this purpose. Using the wrong type of blade can result in poor quality cuts and inaccurate measurements.

5. Not measuring accurately:

Before making any cuts, it’s important to measure the wood carefully and make sure that you are cutting to the correct dimensions. Cutting too small or too large can ruin your project and cause frustration.


Is there any special blade for cutting radius with a scroll saw?

There is a special radius blade that can be used for this purpose. However, you can also use a standard scroll saw blade if you are careful to measure accurately and cut slowly.

Can I cut a curved piece of wood without a scroll saw?

It’s possible to cut a curved piece of wood without a scroll saw, but it will be much more difficult. A scroll saw is specifically designed for this purpose, and it will make the job much easier.

How do you adjust the blade on a scroll saw to cut a radius? 

On most scroll saws, you can adjust the blade to create different radius sizes. Simply loosen the screws on the side of the saw and rotate the blade to the desired position. Be sure to tighten the screws securely when you are finished.

What is a backer board?

A backer board is a piece of wood that is used to support a curved piece of wood while it is being cut. It helps keep the wood from bending or warping and results in cleaner, more accurate cuts.

How do I clamp the wood in place on a scroll saw?

Most scroll saws have a clamping system that will hold the wood in place while you are cutting. Simply adjust the clamps to fit the thickness of your wood, and be sure to tighten them securely.

What is the difference between a standard scroll saw blade and a radius blade?

A standard scroll saw blade is designed for general purpose cutting. A radius blade is specifically designed for cutting curves and radii. It has a smaller tooth count and produces a smoother finish.
