Although a jigsaw is designed to cut thinner materials, it does not limit the ability of the jigsaw. You can successfully cut a 4×4 with a jigsaw using long or multiple jigsaw blades.

How to Measure Dimension

Loggers use different dimension measurements, and the dimensions used are usually not equal to the actual size. Also, hardwood and softwood have other dimension measurements.

The actual size is usually smaller than the nominal size of the wood. When wood has been cut, its size is nominal. However, after drying and planing, the boards reduce in size. The new dimensions are the actual size.

Therefore, a piece of wood with a nominal size of 4×4 has an actual size of 3 ½ inches by 3 ½ inches after drying. So, the actual size is almost half an inch smaller than the nominal size.

A 4×4 is thick but can be cut with a jigsaw. Here are tips for cutting it.

Use multiple saws

No matter how good a jigsaw is, you will always encounter challenges when cutting thick wood, such as a 4×4. However, you can use multiple saws to make cutting easy. Use a jigsaw to cut lines to follow and then use a different saw to cut it through.

Use multiple jigsaws

You can use two jigsaw blades to cut through a 4×4. It helps to minimize flexing, making edges straight compared to one jigsaw blade.

A jigsaw is an easy tool to use. Here are some of the steps to follow when using one:

Step 1: Clamp down the material

Clamp the piece of wood down securely. You can use any clamp, but a C-clamp will be best if you have a large and thick table. 

Step 2: Take safety precautions

It would be best not to use a jigsaw without safety precautions. Since a jigsaw is loud, you need to protect your ears. You can use earmuffs or earplugs since both works equally well.  

Also, do not forget your eyeglasses. Even if you wear regular prescription glasses, you have to wear protective eyeglasses because you are working with a powerful tool.

Step 3: Use the right blade

For every type of cut, there are specific blades. To make a curved cut, you should use a narrow jigsaw blade. On the other hand, you should use a wide jigsaw blade to make an extended straight cut.

In addition, the number of teeth per inch is also vital to consider. A 4×4 requires a blade with fewer teeth per inch, allowing the blade on each stroke to clear more sawdust. 

Step 4: Insert battery

Insert the battery and power up your jigsaw.

Step 5: Make the cut

Now that the jigsaw is powered on, place the jigsaw against the material you want to cut. Run the jigsaw slowly over the material. Do not push it too hard on the material you are cutting. Instead, let the machine do the cutting as you guide it slowly.

Step 6: Let the blade stop running

After cutting, allow the blade to stop completely before lifting it. Then return it to the table or workbench.

Factors That Determine the Thickness a Jigsaw Can Cut

A variety of factors determine what thickness you can cut. These factors include the following:

Type of jigsaw blade

A jigsaw will not be able to cut thicker material. The thickness a jigsaw can cut is determined by the length of the blade below the base of the saw.

Teeth of the jigsaw blade

A jigsaw blade with fewer teeth per inch is suitable for cutting thick material. On the other hand, a jigsaw blade with more teeth per inch can cut thin material better.

Material being cut

A jigsaw can cut different materials, from plastic to wood and metal. There are different types of blades for each material. There is hardwood and softwood for wood, which require slightly different blades.

Power of the jigsaw

A powerful jigsaw that is electrically powered can cut thicker materials, unlike a cordless battery-powered jigsaw.
