Table saws may make long, straight ripping cuts (along the grain) or cross cuts quickly and accurately (against the grain). Miter and bevel cuts can also be made with a table saw.
This power tool is one of the shop’s most powerful and often used equipment. Unlike portable saws, a table saw can make very precise, accurate, and clean cuts over and over again.
Know your saws “maximum cutting depth”
For table saws, the maximum cutting depth varies significantly from one manufacturer to the next.
When looking at the top-rated table saws, you’ll note that almost all of them have a maximum cutting depth of between 3.2” (8cm) and 3.5” (9cm) at 90 degrees.
Disconnect the Power
Table saws, like any other power tool, can be highly dangerous if you don’t use them properly.
As a result, the first thing you can do before doing something else is make sure your table saw is turned off and removed from its power source.
Realize that table saws only tilt 45 degrees in one direction
Remove the Throat Plate and Blade Guard
After you’ve double-checked that your table saw isn’t plugged in, you should remove the throat plate and blade guard. Since all table saws are different, you can need to consult the instruction manual to see how it’s done if you’re not sure.
Know when to use a push stick for cutting pieces on a table saw
It is often advisable to use a push stick when using a table saw for the following operations:
1. Finishing a longer cut by cutting the last 12” (30cm).
2. Cutting bits shorter than 12” (30cm).
3. Cleaning up any scraps that have accumulated on the table.
4. Ripping fabrics with a width of less than 6” (15cm).
Raise the Blade
Boost the blade to its full height after removing the Throat Plate and Blade Guard. This is to make it as simple as possible for you to remove the blade.
Know the difference between cross-cutting and ripping
A ripping cut will be made along the dashed line in the picture below. A ripping cut cuts through the grain of a board. Cross-cutting, on the other hand, cuts a board through its wood. A miter gauge or cross-cut sled is recommended when cross-cutting a board on a table saw.
Loosen the Arbor Nut
A table saw’s blade is fixed in place by an arbor, and in order to separate the blade from the arbor, you must first loosen the arbor nut. A set of wrenches should be included with your table saw for this reason.
The blade is kept immobile with one wrench while the arbor nut on the opposite side is turned with the other.
This move can be done in a variety of ways. At the end of this post, we’ll go over these – and what you can do if you don’t have the requisite wrenches.
Use blades with more teeth to create cleaner cuts
A blade with more teeth can produce cleaner cuts in general than a blade with less teeth. This is due to the fact that there are more teeth cutting and therefore less tear out.
A slower feed rate is usually needed for blades with more teeth. The end result, however, is a cleaner cut.
Know the most common blade size for table saws
A table saw’s most common blade capacity is 10″ (25cm) diameter with a 5/8″ (1.6cm) arbor.
Remove the Arbor Nut with Your Hands
You can unscrew and remove the arbor nut with your fingers after loosening it with the wrench. Make sure the arbor nut does not fall into the table saws shell. After you’ve taken out the arbor nut, you’ll need to take out the washer.
Install or use a riving knife for safety
A riving knife is used to keep wood from jamming and kicking back at the user. A riving knife is located 14” (6mm) behind the blade, matching the curvature of the blade.
The riving knife is attached to the blade so that it moves with it as it is lifted, lowered, and tilted. The knife’s top is just below the blade’s top, so it won’t get in the way of cuts that don’t go all the way through the wood.
The riving knife, according to many experts, is one of the most significant safety features of any table saw.
It almost completely prevents kickback. When the kerfs closes and connects with the blade, it induces kickback. This can occur as a result of poor rip fence alignment, failure to hold the wood against the rip fence, operator error, or stresses in the wood that are released during the cut.
The kerfs cannot connect with the blade when a riving knife is used, so kickback is eliminated.
Remove the Blade and Replace with the New One
You may now remove the blade after removing the arbor nut and washer. Remove the old blade and replace it with a new one.
When doing so, make sure the new blade is pointed in the right direction – the teeth should be pointing towards you, not away from you.
Consider using a “zero clearance insert.”
A table saw’s throat plate has an elongated slot wide enough to allow clearance at all tilting angles. The operator may also use this throat plate to mount different blades, such as a thicker carbide-tip ripping blade.
This wide opening will result in tear-out on the bottom of a work piece and narrow pieces of wood jamming between the saw blade and the throat plate’s slot. To solve this issue, some people make a zero clearance insert with an opening that is the same width as the kerfs of the saw blade.
You may make a new insert by cutting a piece of plywood, phenol resin sheet plastic, or other material to the same size as the original throat plate. The saw is then slowly lifted through the new throat plate, ensuring a perfect match.
It’s important to remember that a zero clearance insert can only be used in one direction. As a result, most people make two zero clearance inserts: one for when the blade is at 90 degrees and one for when the blade is at 45 degrees.
Replace the Washer and the Arbor Nut
After installing the new blade on the arbor, the washer and arbor nut must be replaced.
Know the rip capacity of a table saw
The rip potential refers to the amount of space between the blade and the fence’s edge.
You’ll need at least a 24” (61cm) rip ability to rip a 48” x 96” (122cm x 244cm) piece of plywood into two 24” x 96” (61cm x 244cm) bits.
Replace the Throat Plate and Blade Guard
Replace the blade guard and throat plate. Your new blade has been assembled and is now ready for use.
