How to check and adjust your miter saw for accuracy


Having a miter saw is one thing. Getting it to cut squarely and accurately is another equally important thing which is crucial to the success of your projects.

When you purchase a new miter saw, before it arrives, it’s usually set accurately by the manufacturer at the factory before it is shipped to you. However, due to uncontrollable situations that accompany shipping, it may loss its squareness and accuracy before it gets to you, the user.

Apart from the saw losing its accuracy due to shipping, it can also lose its accuracy during usage. For instance, when sawing a wood, the blade can hit a knot in the wood, and a kickback might occur. This can cause the saw to lose its squareness as well.

In this article, I’ll show you how you can check and inspect your miter saw for accuracy and how to adjust it back to squareness if you discover that the saw is out of adjustment.

Blade Accuracy

In order to make your miter saw cut accurately, it’s needless to say that you have to get the blade square with the miter saw table.

This is quite easy to check. You just have to check if the angle of the blade to the table is 90 degrees. If it’s not, then the blade is not square or not accurate.

To carry out this check, you need a Square rule or square triangle. Once you have that in hand, you need to set up your miter saw on a miter saw stand or on any stable work surface.

For safety reasons, you need to disconnect the miter saw plug from the power outlet to avoid any accident. After that, place your square on the miter saw table, then lower the blade down, making sure the blade teeth avoids the square rule.

Now, adjust the square appropriately until the side comes in contact with the side of the miter saw blade. If the side of the blade comes in complete contact with the side of the saw, then the miter saw is accurate and in good shape.

On the other hand, if there’s a gap between one part of the square rule and the blade, then you know the saw is not square with the table.

There’s usually no cause for alarm here, because you can easily adjust it back so that it’s accurate by just messing with the saw bevel. To adjust this so that it’s accurate, the first thing you need to do is loosen the bevel handle.

After that, you need to adjust the saw bevel until the blade side comes in contact with the square completely. Then you just need to tighten the blade bevel handle to keep it in place.

To ensure that it remains in the 90 degrees position, just make adjustments to the bolt so that it’s just at the 0 degree stop.

This is what it entails to check your miter saw for blade accuracy in order that you get perfect cuts every time you’re working on any new woodworking project.
