Unraveling The Art Of Replacing A Table Saw Arbor

Changing the blade of your table saw is an essential skill for using a table saw. Over time, wear and tear are normal, and it's important to change or replace the blade when it doesn't seem to be working as it should. This guide will show you how to change a table saw blade, including safety tips for working with your saw.

Disconnect power and remove throat plate and blade guard

Disconnecting the power source is the first step in changing a table saw blade. It is imperative that you confirm the saw blade is disconnected from the power outlet to avoid any accidents.

The next step is to remove the throat plate and blade guard to access the blade. The throat plate is usually held in place by fasteners, which need to be unscrewed and removed. Not all table saw machines are built with the same design, so you may need to refer to the instruction manual for this step.

Once the throat plate and blade guard are removed, the blade height should be adjusted to its maximum height. This makes it easier to access the nuts and bolts holding the blade in place.

At this point, you are ready to loosen the arbor nut, which is located in the centre of the blade. This step requires a little strength and the use of two wrenches. Hold one wrench on the nut to keep it stationary while using the other wrench to move and loosen it.

With the arbor nut loosened, you can now proceed to the next steps of removing the nut, washer, and eventually the blade itself.

Raise blade to max height and loosen arbor nut

To change the blade of your table saw, you must first raise the blade to its highest point to ease access to the arbor nut. The arbor is the shaft that the blade is mounted on. Once the blade is raised, locate the arbor nut at the centre of the blade.

To loosen the arbor nut, you will need two wrenches. Hold one wrench on the nut while using the other wrench to keep the other side of the arbor nut stationary. This process can require a little strength. If your table saw comes with an arbor lock, you will only need one wrench. In this case, push down on the arbor lock with one hand while using the other hand to loosen the nut with a wrench.

Once the nut is loose, hold onto the arbor nut and slowly rotate it using your thumb and index finger. Remove the nut, being careful not to let it fall into the machine. Then, slowly remove the washer.

Remove arbor nut and washer, then blade

Removing the arbor nut and washer is a crucial step in changing the blade of your table saw. Here is a detailed, step-by-step guide to help you with this process:

Locate the Arbor Nut and Prepare for Removal

The arbor nut is generally present at the centre of the blade. You will need two wrenches for this process – one to hold the nut and the other to keep the other side of the arbor nut stationary while loosening it. If your table saw comes with an arbor lock, you will only need one wrench. In that case, push down on the arbor lock while using the other hand to loosen the nut with a wrench.

Loosen and Remove the Arbor Nut

Loosen the arbor nut by holding it with one wrench and moving it while keeping the other side stationary with the other wrench. Once it is properly loosened, continue to unscrew it further and take it out from the bracket. Be careful not to drop the nut inside the machine, and make sure to place it securely when removed.

Remove the Washer

With the arbor nut removed, slowly remove the washer. Again, be cautious not to drop it inside the machine, and place it securely with the arbor nut.

Remove the Blade

With the washer and arbor nut removed, there is nothing holding the blade in place, so you can simply take it out of the machine. Place the blade on a work surface or another secure location.

By following these steps, you will have successfully removed the arbor nut, washer, and blade from your table saw. Remember to refer to the instruction manual for your specific model, as some variations may exist between different table saw designs.

Insert new blade, washer, and arbor nut

Now it's time to install the new blade. The new blade must be inserted in the correct orientation. The teeth of the new blade should be pointing towards you, not in the opposite direction. If installed incorrectly, the workpiece may fly off the table saw. You can check the arrow on the blade to ensure the correct direction.

Next, replace the washer and arbor nut. Ensure that the washer is compatible with the new blade. Place the washer and arbor nut into the arbor, and tighten the nut firmly. Be careful to thread the nut on properly. If it is difficult to turn, stop and try again. Tighten the nut, being careful not to strip the threads.

Before returning all of the guards to their places, turn the blade by hand to check that it’s in straight. Any wobble is an indication that something went wrong and the process should be repeated. Ensure that the blade is held tightly in place and isn’t spinning freely on the arbor.

Return throat plate and reconnect power

Now that you have successfully changed the blade of your table saw, it's time to return the throat plate and reconnect the power.

Return the throat plate

First, replace the throat plate and blade guard. Your table saw model may require a specific procedure for this step, so be sure to consult the user manual. Ensure that the throat plate is securely locked in place.

Reconnect the power

Finally, reconnect the power source to your table saw. Before powering on the saw, double-check that all components are securely fastened and correctly installed. Test the new blade by performing a test cut using scrap material or a common board. Ensure the blade is cutting cleanly and set to the appropriate angle.
