A table saw, also known as a bench saw, is an important yet beneficial woodworking tool. Owing to the versatility and accuracy offered by a table saw, it is frequently seen at wood shops.
This type of saw is called a table saw because the blade is jutted out on top of the table. The table supports the material being cut. The blade, on the other hand, is mounted on an arbor.
The arbor is like an axle which supports and rotates the blade. The arbour, in turn, is driven by the help of an electric motor, either directly or indirectly through a belt or gears.
The problem arises when the key component of your table saw wears out. The blade plays a fundamental role in effectively cutting the wood. However, when it starts deteriorating, the efficiency is reduced.
Another possible reason can be the change of job. If you want to do some other task which is different from the former one, you may need to change the blade.
In any case scenario, if you feel the need to change your table saw’s blade, the article will guide you to the right procedure. Along with propping up the saw’s efficiency, the ability to change the blade can also grant you versatility.
Ways to Change the Blade of Your Table Saw
With time, the teeth of your saw’s blade wear away and even after sharpening them, the same cutting strength is not attained. Also, you can get bored of making the same cuts every time. This is how you can change the blade of your table saw:
Step 1: Take the Safety Precautions
As we all know, the table saw is operated by electrical power. Besides, there is a riving knife you are going to change. There are a lot of risks involved.
For this purpose, make sure to unplug the machine before starting the tutorial. Also, wear some safety gloves to protect your hands from injuries.
Step 2: Get Access to the Blade
Your table saw blade is located somewhere in between the throat plate and below the blade guard. They are to prevent the kickback of the work piece and direct contact of the operating hands with the blade.
However, every saw comes with a slightly different procedure to remove the throat plate and blade guard. Check the manufacturer’s guide to get proper instruction.
Step 3: Draw the Blade Up
Once you have successfully removed the blade guard and throat plate, you can access the blade easily. Raise it to the maximum possible height. This will give you a clear view and access to the blade.
Step 4: Unfasten the Arbor Nut and Washer
On raising the blade, you will realize that it is connected to a shaft fastened with a nut. This shaft is called the arbor.
Your table saw like most others, must have come with a set of two wrenches. One of them is used to have a firm grip of the blade and the other is to loosen the nut.
If for some reason, you don’t find this pair of wrenches, you can go for the following options:
- The adjustable wrench is what you can utilize as an alternative. Take the wrench and adjust it following the nut size. If you have two, you can utilize one for fastening the nut and other for holding the arbor immobile.
- An open-ended wrench can also be utilized for the purpose. Find one which is fixed in the nut rightly. If you have two, you can use them for the same purpose as the pair of wrenches.
- If instead of two, you have a single wrench, you can use a wooden block for holding the blade. Jam the blade by wedging in the wooden block, and start loosening the nut.
- You can also get a blade lock to hold the blade in position. It also protects your hands from uninvited injuries.
- Some table saws, particularly the small ones, come with an arbor lock system. A small lever near the arbor is used to halt the movement of the blade. You can utilize this option if you only have a single wrench.
Step 5: Take Off the Blade
After the wrench has unfastened the nut, you can simply remove it by hand. Using fingers to remove the nut is a precaution so that the nut does not fall and get lost in the base of the table saw.
Now remove the washer and your worn-out blade is all free to be taken off.
Step 6: Bring in the New Blade
Eventually, your blade has been removed now. Bring in the new one and place it in the right position. Preferably, the perfect position is when the teeth of the blade are pointing toward you.
Handle the blades safely as mishandling may lead to injury.
Step 7: Fasten the Nut and Washer
After setting the blade in the right position, start tightening it by the washer and nut. Place the washer in the accurate position and fasten the nut by the same procedure followed to unfasten it.
If you have used two washers you can utilize them again by moving one washer in the direction of the other holding the blade tightly. Make sure the geometry is strong and the nut is tightened properly.
Step 8: Place Back the Throat Plate and the Blade Guard
Complete the final stage of installation by setting back the throat plate and the blade guard. It is necessary to ensure that everything is reset at their previous position without any error.
An error may cause the blade to not function properly or an accident may occur.
After verifying flawless geometry, you can plug in the table saw and start operating again.
Table saw is an efficient device when it comes to cutting jobs with versatility. However, long-term use may result in inefficiency of the machine which is inevitable. For renewing your table saw to bring back the old cutting precision, this guide is all you need to do.
