How to square a miter saw

How to square a miter saw – A Miter saw is a powerful tool that can cut angled joints. It has a horizontal blade, which cuts along the length of the wood, and it uses gravity to tilt the blade into the miter. The saw has two parts to it. One part contains the blade and the other holds the saw’s mechanism that changes angles between 0, 15, 22.5, 30, 45, and 67.5 degrees.

The saw is used to cut at an angle across the width of the wood. It is important that the saw is square before any cuts are made, as an incorrect angle can result in a poor quality finish or even injuries.

What Is Squaring Your Miter Saw?

Squaring your miter saw is setting the angle of the saw to zero degrees, or at zero degrees. This means that when you make a cut with the saw (for example cutting a piece of wood), the blade will be perpendicular to the side being cut. If the blade isn’t perpendicular, the cut will be skewed and the result won’t be as precise as you might hope.

In this article, we will show you how to square a miter saw with step by step Procedure.

How to square a miter saw

A miter saw is a versatile tool that can be used for a variety of projects, from framing to trimming. However, in order to get the most accurate cuts, it’s important to square the saw. Let’s get started.

Step 1:

First, you’ll need to find the back of the saw’s arbor. An arbor is a large bolt on the underside of your miter saw that holds the blade in place. Simply flip it over so you can see the underside of the saw, unscrew the nut with an adjustable wrench and remove it.

Step 2:

Next, align your square or ruler with one of the lines on your saw’s blade and draw a line across.

Step 3:

Rotate the saw to the other corner, aligning your square or ruler with that edge of the blade and drawing another line. You should end up with two intersecting lines drawn across your blade as seen in the picture below.

Step 4:

Now, it’s time to measure the distance between the lines. This can be done with a dial indicator, ruler or any other method you choose.

Step 5:

Once you have your measurement, it’s time to adjust the blade. Loosen the arbor nut by turning it counter-clockwise and then turn the adjusting bolt until the distance between the lines is equal all around it. Then tighten down the nut, make sure your blade hasn’t changed position, and recheck.

Step 6:

If there’s still a gap, you’ll need to adjust your miter saw’s fence. Simply loosen the two bolts on either side of the fence with an adjustable wrench or socket set and adjust it accordingly.

Step 7:

Re-tighten the bolts on the fence and check again that there’s no more gap between the lines.

Step 8:

The last step is to replace the arbor nut. Line up your wrench with the bolt on the underside of the saw and turn clockwise until it’s nice and snug against the saw’s body.

Step 9:

Give it one last check, then flip your saw back over and you’re ready to go! With these simple steps, you can ensure that all of your cuts with your miter saw are accurate and square.


Q: Why Is Squaring Your Miter Saw Important?

When making cuts with a miter saw, it’s important that the blade is perpendicular to the side of the wood being cut for two reasons: accuracy and safety. An inaccurate cut can mean that your project isn’t the right size or shape, and a skewed blade can lead to dangerous kickback.

Q: What Is Kickback?

Kickback is when the blade grabs the wood and drives it back towards you. This can lead to injuries if you’re not prepared, so it’s important to be cautious when using your saw.

Q: Why Does The Blade Need To Be Perpendicular With The Wood?

When you cut a piece of wood with a miter saw, the blade spins and cuts through the wood. If the blade is perpendicular to the side being cut, then the resulting angle will be 90 degrees or less because there is no need for an equal force from the left or right to skew the cut. So even if you’re just cutting a piece of wood into smaller pieces, it’s important that your blade is perpendicular to the board so the resulting cuts are as accurate as they can be.

Q: What Can I Do To Keep My Miter Saw Perpendicular?

There are two things you can do to keep your miter saw from skewing the blade. The first is to check your miter saw for any play in the blade. If there’s a significant amount of play, then that will cause your cuts to skew because the angle isn’t being kept constant throughout a single cut. You should try squaring up your miter saw by using this guide and if there is still play in the blade, you should remove it and address it.

The second thing you can do to keep your miter saw from skewing is to make sure that the saw’s guide is perpendicular to the blade. You can use a framing square or similar tool to check this angle and correct for any misalignment between them.

Q: I’m Having Trouble Squaring My Miter Saw. What Do I Do?

If you’re having trouble squaring your miter saw, there are a few things you can do. The first is to check the blade for play and if there’s significant movement, address it. You can also make sure that the saw’s guide is perpendicular with the blade and if you’re still having trouble, then most likely the table is misaligned with the saw’s guide.

Conclusion: How to square a miter saw

Miter saws are a great tool to have in your arsenal, but it’s important that you make sure the blade is perpendicular to the side of the wood being cut for accuracy and safety. There are a few ways to do this, and if you’re having trouble, there are plenty of resources available to help you out. So don’t be afraid to take your trusted miter saw out of the box and use it. Just be sure to keep it square!
