How To Cut Plywood With A Jigsaw – The Easiest Procedure

A jigsaw is a popular tool with skilled woodworkers. If it is available at home, you can try to use it and make some simple furniture. The process is not very complicated, but you need to learn some necessary information in advance. For starters learning to use this tool, why not learn from basic skills like cutting plywood with the jigsaw?  

Let’s discover and learn “How to cut plywood with a jigsaw?” with useful information below. Check it out now!

What Is The Jigsaw?

A jigsaw is a device that has a reciprocating blade that facilitates wood cutting. People also use it for many other materials such as plywood, plastic, or metal.

Jigsaw is useful with almost all cutting techniques, including curved cuts. On the downside, its capacity may be slightly reduced if the thickness of the material is over 1 inch.

The main power source of this device comes from electricity. However, lithium-ion or nickel-cadmium jigsaws have gradually become popular.

The Components Of A Jigsaw

Although manufacturers continually create many useful improvements for buyers, a jigsaw always has some of the main components below:

Shoe Adjustment 

It is a metal part of the jigsaw base that tilts the blade from 0 to 45 degrees. As a result, the user places it on top of the wood to make bevel cuts.

Another effect of it is to fix the blade so that the cutting process takes place more safely.

Power Button

For the Barrel grip jigsaw, this part is usually located on the side. In comparison, the rest of the models have it below the handle.

It is needless to discuss the use of this part. However, it is important to turn off the device when performing any action with the blade. 

Blade Clamp

The function of this component is to fix the blade with at least two screws. Besides, they do not affect the blade change process. Without a key, you need to loosen the spring lever to release the blade.

Blade Roller Guide

It is located at the top of the shoe adjustment to keep the blade from bending when cutting.

Main Types Of Jigsaw

You can find a lot of jigsaw designs in stores. In fact, there are only two main categories below:

Top Handle Jigsaws

The general design of this type is the separate handle at the top. Also, the start button is located above the motor. 

This design provides the greatest convenience for straight cuts. Still, it possibly obstructs your view when cutting curved or beveled.

Barrel Grip Jigsaws

By comparison, this type has a handle integrated into the body of the device. This jigsaw type provides better visibility than the rest, so it is quite popular in furniture design.

On the downside, the handle may not fit some people due to its large circumference.

The Jigsaw Pendulum Motion

Some manufacturers have applied this new technology to modern jigsaws. To be more specific, its biggest benefit is to allow the user to move the blade back and forth or in a circular direction. 

You can even adjust 3-4 levels of motion. The higher it is, the rougher the object’s surface becomes. Hence, we do not recommend this pendulum for thin and fragile materials.

Different Techniques With Jigsaw

Bevel Cuts

The proper protractor becomes your savior for the best result. You can also manually adjust the angle of the jigsaw shoe. 

Generally, it would be best to use this cutting technique to create corner trims for edges with joints at 45 degrees.

Straight Cuts

This basic cutting technique does not require too much practice. However, those new to jigsaw should draw a marker line before cutting to achieve the desired result.

Parallel Cuts

You can make parallel cuts similar to straight cuts. Meanwhile, it is mandatory to install the cutting guide. Do not forget to adjust the slider length to create the width of the guide as you want.

Circle Cuts

This technique has similarities to the two above. Specifically, you just need to change the right guide. Then place the end of the guide in the center of the circle you want to cut and rotate the jigsaw around.

How To Cut Plywood With A Jigsaw

The process is easy as a piece of cake. Here is how to do:

Step 1: Check The Tooth Orientation

The difference in tooth orientation produces distinct plywood faces and edges. For example, you should use the blade with the upward tooth for a smooth surface.  

It would help if you also considered the teeth-per-inch (TPI) rating. Typically, this standard includes an assessment of 10 to 20 TPI. Low TPI value means fast cutting speed but poor edge smoothness. 

Step 2: Define The Cut Line

Pre-planning a line before cutting makes the work process easier and less error-prone. Place the plywood on a flat surface, then use a wooden pencil and ruler to make the intended markings.

Step 3: Adjust The Blade Speed 

If your modern jigsaw has an Orbital mode, do not forget to adjust the blade trajectory to the right level. We recommend a moderate movement to avoid breaking the plywood.

As mentioned above, it would be best to check for the jigsaw pendulum motion. Slow speed limits deep cuts into the edge and sawdust release.

Step 4: Install The Suction Tube

The basic function of this unit is to act as a sawdust extractor. Therefore, do not skip this step for clearer vision while working.

Step 5: Let The JigSaw Do Its Work

Place the blade above the previously marked line and then turn on the switch. Hold the jigsaw with both hands and stand in the position that feels most comfortable to you. Finally, do the plywood cutting slowly and carefully.
