Another important safety device is the magnetic switch. This device protects you after an electrical power failure. If the power fails and you have a regular switch, the saw will come back on when the power comes back on. If you were to be near the blade at the time, this could be disastrous. A magnetic switch will not allow the saw to start again until you press the button. The location of the switch is also important. It should be right out front where it can be quickly accessed by a hand, foot or knee in the event of an emergency. The off button should be wide, red in color and should extend outside of the switch box like a mushroom for fast access.
There are many hold-down and anti-kickback devices on the market. Some are good and some are a hazard in themselves. I had a large metal combination hold-down and anti-kickback device get caught in the saw blade, ripped off the fence to which it was clamped and flung into a plate glass door behind the saw. I heard it go whistling past my right ear. It missed me because I was standing, as always, well to the left of the saw blade.
In the modern table saw, regardless of type, the depth of a cut is changed by adjusting the distance that the blade sticks out above the table surface. The more the blade protrudes from the table, the deeper the cut that is made in the material will be. Conversely, the less a blade protrudes from the table, the more shallow the cut that is made in the material being cut, will be.
The saw blade is mounted on an arbor with an arbor nut and the arbor is turned by the motor usually via pulleys and 1 to 3 V-belts. The arbor is mounted into the trunnion inside two or more arbor bearings. These should be sealed from dust for obvious reasons. The size of the arbor determines the size of the hole in the middle of the saw blade. This is usually 5/8" for a 10" blade and 1" or larger for blades larger than that. The strength and alignment of the arbor and the bearings which support it determine the accuracy and smoothness of the table saw. Vibration and noise should be kept to a minimum and the saw blade should be straight in the table from front to back at all elevations and bevel angles.
This last type of table saw also appealing to the customer base on table saw reviews. It is maybe due to its features that are somewhat similar to those of the cabinet and contractor table saw. Just like the cabinet table saw, it also has a solid base with also lesser vibration and provides dust control. It is also compact just like the contractor saw but the thing is that it is much compressed than the first mentioned. However, this saw inclines to weigh less than a cabinet table saw but heftier than the contractor table saw. This makes it intended for most of woodworkers.
