How To Cut a Straight Line With a Jigsaw In 9 Easy Steps

How to cut a straight line with a jigsaw

For all of you DIY enthusiasts wondering, How to cut a straight line with a Jigsaw? The answer to this question is not as simple as you may think. Jigsaws are the tool of choice when it comes to cutting curved lines in wood but it is also possible to use them for cutting straight lines or straight across, edge to edge. This isn’t however, the first preference that comes to mind.

The reason being that the motor vibrating in the jigsaw, moving the blade at a rapid speed, doesn’t inspire the kind of confidence you need for cutting in a straight line. In most cases, you need external support in addition to the jigsaw for cutting straight lines. With experience, however, you can become accomplished enough to make straight cuts without relying on support. But as any self-respecting tool user knows, it is more important to be precise than bold. So using tools for support is a better choice than not using them.

Jigsaws can cut straight lines not just through wood alone but also other materials including laminates, plastic, and metal sheets, or even tiles. And neither are you limiting in making just one type of cut. Using a jigsaw you are more than empowered to make cross cuts, bevel cuts, miter cuts, or even cut a straight line from the center of the material for plunge cuts. You can even cut circle with jigsaw. In short, a jigsaw is the best saw for cutting shapes out of wood

So let’s get into this strange world of jig saw cutting

What do you need to cut straight lines with a Jigsaw?

Measuring tape: 

To make sure that the cuts you make are precise and according to your needs.

Pencil or marker: 

To mark your cuts and points, very important to mark the line before you start cutting. Use pencils or markers that are dark and can be cleaned, if the need be. It would be troublesome If you make an error while marking and end up with multiple faintly visible lines when you get to cutting with the jigsaw.

Clamps: 

For cutting straight line with a jigsaw you need stability. To hold the material steady since the vibrations from the motor might shake things up too much. The clamps will keep the material in place while you cut along.

Masking tape: 

To mark over the material. Using masking tape will make marking your cuts a lot easier and it will be especially useful for separating the waste side of the material.

5 Degree angle: 

The Jigsaw Angle cut is essential for making sure your measurements are accurate. You can also use a straight lumber bar to act as a guide for your cuts. Especially when making the longer cuts. By doing so you will have something to support your jigsaw while you make the cuts. The jigsaw straight cut guide will keep your movements stable and provide your cuts with much-needed stability.

A jigsaw blade with reversed teeth:

 It is important to choose the right blade for the job you are doing. The key things to look for are the blade’s flexibility and teeth. The more TPI (Teeth Per Inch) a blade has the more fine cuts it will make and the more flexible it is the more risk there is of the blade wobbling off from your marked cutting lines. So when selecting a blade make sure it is not a very flexible one since that will allow you to take clean, stable, and precise cuts.

How to cut straight with a jigsaw tool? Just choose the blade wisely. Focus on the direction of the teeth. For making straight cuts it helps to use a blade with teeth whose direction is reversed. This way you won’t have to make cuts in the opposite direction and your blades will be less likely to chip the material you are cutting. This will be greatly beneficial when applying masking tape as your support.
